Key Features

  • 600 W peak-pulse power dissipation with 16 V nominal breakdown voltage (15.2 V min / 16.8 V max) provides tight unidirectional clamping for 12 V and 15 V DC bus protection
  • 22.5 V maximum clamping voltage at peak pulse current ensures downstream circuitry is protected against ESD and inductive switching transients with excellent clamping capability
  • Silicon axial through-hole package (DO-15 style) enables simple hand or wave soldering and direct insertion into legacy and new PCB designs for high-reliability transient protection

Applications

P6KE16A-E3/54 protects 12 V and 15 V power rails and signal lines in industrial equipment, automotive accessories, and telecommunications gear from inductive load-dump transients, ESD events, and lightning surges. Its 600 W peak-pulse capability handles the high-energy transients that occur when inductive loads such as relays, solenoids, and DC motors are switched off in 12 V DC systems. The axial package is also widely used as a clamping diode across DC bus lines in motor drives, power distribution units, and reverse-polarity protection circuits.

Frequently Asked Questions

What is the standoff and clamping voltage of P6KE16A-E3/54 and which bus voltages does it protect?

P6KE16A-E3/54 has a 16 V nominal breakdown voltage (15.2 V min, 16.8 V max) and clamps transients to a maximum of 22.5 V under peak pulse current. This makes it ideal for protecting 12 V DC automotive and industrial power buses where transient spikes must be held below 22.5 V to prevent damage to downstream ICs and FETs.

How much peak-pulse power can P6KE16A-E3/54 absorb during a transient event?

P6KE16A-E3/54 is rated for 600 W peak-pulse power dissipation based on a 10/1000 µs test waveform per IEC 61000-4-5. This is sufficient to absorb the energy from inductive load-dump transients generated when a 12 V DC relay or solenoid coil is de-energized, protecting downstream gate drivers and analog front-end circuits from destruction.

Why choose a unidirectional TVS like P6KE16A-E3/54 over a bidirectional version for a 12 V DC supply rail?

On a DC power rail such as 12 V, only positive-polarity overvoltage transients are present in normal operation. A unidirectional TVS like P6KE16A-E3/54 conducts heavily in one direction to clamp positive spikes to 22.5 V while blocking in the reverse direction, allowing the rail to sit at 12 V to 16 V without forward-biasing the device. A bidirectional version would clamp both polarities but adds unnecessary capacitance on DC signal lines.

What package does P6KE16A-E3/54 use and how does it mount on a PCB?

P6KE16A-E3/54 is supplied in an axial DO-15 style through-hole package with horizontal PCB mounting. Axial leads allow the device to be laid flat between two mounting holes on a standard 5 mm to 10 mm pitch, enabling hand soldering, wave soldering, and automated insertion on through-hole PCBs used in industrial control and power conversion designs.

How does P6KE16A-E3/54 compare to a lower-voltage P6KE12A when protecting a 12 V bus?

P6KE12A has a 12 V nominal breakdown and clamps at approximately 16.7 V, which risks occasional nuisance triggering on a 12 V bus that routinely reaches 13.8 V during battery charging. P6KE16A-E3/54 with its 15.2 V minimum breakdown stays off during normal 12 V to 14 V operation and only activates above 15.2 V, avoiding unnecessary clamping while still protecting against transients above 22.5 V in the same 600 W peak-pulse envelope.
