Key Features

  • Dual 16 A ultrafast recovery diode in common-cathode configuration for compact full-bridge and freewheeling circuits
  • 400 V blocking voltage with 1.75 V max forward voltage for efficient rectification in medium-voltage SMPS designs
  • Soft recovery factor of 0.4 reduces reverse-recovery EMI noise in motor drive and PFC freewheeling applications

Applications

The STTH16R04CG-TR is used as a freewheeling diode in motor drive inverters, switch-mode power supplies, and power factor correction stages where low EMI and fast recovery are critical. The 400 V, 16 A rating with a soft recovery factor of 0.4 makes it well suited for bridge rectifier topologies in industrial converters operating from 200 V AC mains. The common-cathode dual configuration simplifies PCB layout in half-bridge and full-bridge designs by sharing a single cathode connection.

Frequently Asked Questions

What is the reverse recovery behavior of STTH16R04CG-TR, and why does it matter in a motor drive freewheeling application?

The STTH16R04CG-TR is classified as an ultrafast recovery rectifier with a soft recovery factor of 0.4, meaning its reverse current tail decays gradually rather than abruptly. In a 400 V motor drive freewheeling circuit, this soft characteristic reduces the di/dt spike during turn-off, lowering conducted and radiated EMI and reducing voltage stress on the switching transistors in the same 16 A bridge.

How does the common-cathode dual configuration of STTH16R04CG-TR simplify PCB layout in a bridge converter?

By sharing a single cathode pin between 2 independent 16 A diode elements, the STTH16R04CG-TR allows both upper freewheeling diodes in a half-bridge stage to connect to the positive DC bus through one package terminal. This eliminates a separate interconnect trace and reduces the parasitic inductance in the high-side loop, which is especially valuable in 400 V SMPS designs where layout inductance directly affects switching noise.

What power dissipation should be budgeted when using STTH16R04CG-TR at its 16 A rated current?

At 16 A forward current, the 1.75 V maximum forward voltage implies a worst-case conduction loss of approximately 28 W per element, so the dual device can dissipate up to 56 W in continuous operation. Designers must provide adequate heatsinking on the 25-week lead-time PSSO-G2 package to keep junction temperature within the silicon diode's rated thermal limits for long-term reliability in 400 V rectifier stages.
