Key Features
- 600 W peak pulse power dissipation for robust single-polarity transient protection
- 150 V nominal breakdown voltage with tight ±5% tolerance (143 V to 158 V)
- 265 V maximum clamping voltage to limit transient overvoltage events on protected rails
- UL recognized DO-15 through-hole package with high 400 pF capacitance for low-frequency line filtering
Applications
The P6KE150A is suited for protecting 120 V AC rectified DC bus rails, industrial control systems, and power supply input stages from transient overvoltage events. Its 600 W pulse rating and 150 V breakdown voltage make it effective in equipment exposed to lightning surges, inductive load switching, and ESD in factory automation environments. It is commonly deployed on the DC output of bridge rectifiers in variable-speed drives and SMPS front-end circuits where voltage spikes must be clamped below 265 V.

Frequently Asked Questions
What is the maximum clamping voltage of the P6KE150A, and which DC bus voltage levels does it suit?
The P6KE150A clamps transients to a maximum of 265 V at rated peak pulse current. This makes it suitable for protecting DC bus rails derived from 120 V AC rectification, where the nominal rectified voltage is approximately 170 V DC and short-duration spikes must be suppressed below 265 V to protect downstream semiconductors.
How does the P6KE150A's 400 pF junction capacitance affect its suitability for high-speed data line protection?
The P6KE150A has a minimum junction capacitance of 400 pF, which is relatively high and limits signal bandwidth to well below 1 MHz at typical impedances. This capacitance makes the device unsuitable for high-speed data line protection but acceptable for low-frequency power rail and AC line transient suppression applications.
For a 130 V DC industrial supply rail, can the P6KE150A be used without triggering nuisance clamping under normal conditions?
The P6KE150A has a minimum breakdown voltage of 143 V, which provides a 13 V margin above a 130 V DC supply rail under normal operation. Designers should verify that supply voltage tolerance and ripple do not push the rail above 143 V, as sustained overvoltage within the breakdown range could cause unintended conduction and potential device stress.
What peak pulse power can the P6KE150A handle, and for how long during a standard transient test?
The P6KE150A handles 600 W of peak pulse power for a 10/1000 µs standard waveform, which represents a 10-microsecond rise and 1000-microsecond decay transient pulse. This 600 W rating ensures the device can absorb energy from typical lightning and surge events without damage during single non-repetitive transient conditions.
When would a designer choose the P6KE150A over a lower-voltage P6KE series device such as P6KE100A for surge protection?
A designer selects the P6KE150A when protecting circuits operating on 120 V AC rectified rails or 110 V to 130 V DC buses, where the 100 V breakdown of the P6KE100A would be too close to the operating voltage. The P6KE150A's 143 V minimum breakdown voltage provides adequate standoff for higher-voltage systems while maintaining 600 W peak pulse capability and a 265 V clamp ceiling.
