Product details
Overview
STTH16R04CG-TR from STMicroelectronics is a 400 V, 16 A dual common-cathode ultrafast recovery diode in D²PAK surface-mount package, featuring 25 ns typical reverse recovery time (trr), 0.9 V typical forward voltage (VF) at 8 A and 25 °C, and 175 °C maximum junction temperature - optimized for high-frequency inverters and freewheeling in low-voltage power conversion.
For engineers reviewing the STTH16R04CG-TR datasheet, STTH16R04CG-TR pinout, STTH16R04CG-TR application, or STTH16R04CG-TR equivalent, key selection criteria include trr ≤ 35 ns at 125 °C, VF ≤ 1.37 V at 150 °C/16 A, dual-diode thermal coupling behavior, and D²PAK thermal resistance (Rth(j–c) = 1.15 °C/W per device).
Technical Context
This dual-diode device uses ST's planar platinum-doped silicon technology to achieve soft, ultrafast reverse recovery with S-factor ≥ 0.4 and low stored charge (Qrr typ. 30 nC at dIF/dt = –200 A/µs). It operates across –40 to +175 °C junction range with rated repetitive peak reverse voltage of 400 V and surge current capability of 120 A (10 ms sinusoidal).
The D²PAK package enables high-power density mounting with 1.15 °C/W junction-to-case thermal resistance per device, and its dual common-cathode configuration supports interleaved or parallel switching paths while sharing thermal mass - critical for synchronous rectification and bidirectional clamp circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - blocks up to 400 V reverse voltage without breakdown; suitable for 300 V DC bus applications with margin. |
| IF(AV) | 16 A (per device) at TC = 145 °C - continuous average forward current rating under heatsink-limited thermal conditions. |
| trr (typ) | 25 ns at Tj = 25 °C, IF = 1 A, VR = 30 V, dIF/dt = –100 A/µs - enables >1 MHz switching in resonant converters. |
| VF (typ) | 0.9 V at Tj = 25 °C, IF = 8 A - low conduction loss improves efficiency in high-duty-cycle freewheeling paths. |
| Rth(j–c) | 1.15 °C/W (per device) - defines thermal path from junction to case; used with heatsink Rth(c–a) to calculate max power dissipation. |
| IRM (max) | 8 A at Tj = 125 °C, IF = 8 A, VR = 320 V, dIF/dt = –200 A/µs - peak reverse recovery current determines snubber sizing and EMI filtering needs. |
| Tj (max) | +175 °C - allows operation in high-ambient environments (e.g., automotive under-hood, industrial motor drives) without derating. |
Pinout & Package
STTH16R04CG-TR is housed in a D²PAK (TO-263AB) surface-mount package with three terminals: two anodes (A1, A2) and one common cathode (K). The package features a copper-exposed thermal pad on the underside for direct PCB thermal conduction and mechanical anchoring.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Input terminal for first diode path; electrically isolated from A2 but thermally coupled via shared die substrate. |
| A2 | Anode 2 | Input terminal for second diode path; enables dual-channel freewheeling or phase-leg anti-parallel configuration. |
| K | Common Cathode | Shared output node; connects both diodes' cathodes internally - simplifies PCB routing in half-bridge or dual-output topologies. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery | trr ≤ 35 ns (max) at 125 °C ensures minimal switching loss and reduced EMI in hard-switched SMPS above 200 kHz. |
| Dual common-cathode topology | Enables compact layout for complementary switching legs (e.g., IGBT/MOSFET anti-parallel clamping) without discrete interconnects. |
| High junction temperature rating | 175 °C max Tj allows sustained operation in sealed enclosures or high-ambient industrial environments without forced cooling. |
| ECOPACK®2 compliance | Meets RoHS and halogen-free requirements; epoxy meets UL 94 V0 - suitable for consumer, industrial, and automotive end equipment. |
| Low thermal resistance | Rth(j–c) = 1.15 °C/W (per device) supports >20 W power dissipation with standard 2-layer FR4 PCB copper area (≥10 cm²). |
Applications
| Motor Drive Inverter | DC–DC Boost Converter |
|---|---|
|
Use Scenario: Freewheeling path in 3-phase BLDC inverter with 200–400 V DC bus and 20–50 kHz PWM. IC Role / Device Role / Timing Role: Anti-parallel clamping diode across IGBTs; recovers before next switching edge to prevent shoot-through.

| Solar Microinverter | Industrial UPS Rectifier |
|
Use Scenario: Bidirectional energy transfer path in transformerless microinverter H-bridge stage interfacing PV panels to grid. IC Role / Device Role / Timing Role: Common-cathode dual diode provides synchronous rectification and reverse polarity protection in AC-coupled topology. Use Value: Dual-anode configuration eliminates need for two separate diodes, reducing board space by 35% and thermal mismatch between channels. |
Use Scenario: Input-stage freewheeling diode in 48 V–380 V industrial UPS where reliability and thermal robustness are critical. IC Role / Device Role / Timing Role: High-current, high-temperature freewheeling element in battery-charging and bypass circuits.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast dual-diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH16R04DJ-TR | Dual common-anode configuration (vs. common-cathode); identical VRRM, trr, and VF specs. | Requires inverted PCB layout and gate-drive timing; suited for active-clamp or resonant LLC secondary-side rectification. | Select when circuit topology demands anode-referenced dual diodes - not a drop-in replacement for STTH16R04CG-TR. |
| IXYS MUR1640CT | Higher VF (1.25 V typ. @ 8 A), slower trr (50 ns typ.), TO-220AB package only - no D²PAK option. | Limited to lower-frequency (<100 kHz), through-hole assembly; unsuitable for high-density SMT layouts or >300 kHz operation. | Use only if D²PAK is unavailable and thermal budget allows higher conduction loss; verify PCB footprint compatibility. |
Compared with STTH16R04DJ-TR and MUR1640CT, STTH16R04CG-TR uniquely combines D²PAK surface-mountability, common-cathode topology, and sub-30 ns trr - making it optimal for space-constrained, high-frequency motor drive and solar inverter designs requiring thermal coupling and layout simplicity.

FAQ
What is the maximum allowable case temperature for continuous operation?
The STTH16R04CG-TR is rated for continuous operation with case temperature (TC) up to 145 °C when delivering 16 A average forward current. At TC = 150 °C, derating applies per Figure 1 in the datasheet; thermal design must ensure Rth(j–c) × Pdiss + TC ≤ 175 °C.
Can this diode be used in parallel configurations?
Yes - the dual common-cathode structure and matched die characteristics support paralleling of multiple STTH16R04CG-TR units. However, individual current sharing requires symmetrical PCB layout, equal trace inductance, and thermal coupling; external ballast resistors are not recommended due to efficiency loss.
Is the D²PAK thermal pad required to be soldered to the PCB?
Yes - the exposed thermal pad (pin K side) must be fully soldered to a minimum 10 cm² copper pour on the PCB's inner or outer layer. Omitting this connection increases Rth(j–c) by >3× and risks thermal runaway at >8 A continuous load.
Does STTH16R04CG-TR meet automotive AEC-Q101 requirements?
No - STTH16R04CG-TR is qualified for industrial-grade operation (–40 to +175 °C) but is not AEC-Q101 certified. For automotive applications, ST recommends the AEC-Q101-qualified STTH16R04CW-TR variant, which shares identical electrical specs but undergoes additional stress testing.
