Product details
Overview
STTH60R04W from STMicroelectronics is an ultrafast recovery silicon rectifier diode using platinum-doped planar technology, rated for 400 V repetitive peak reverse voltage, 60 A average forward current at Tc = 110 °C, and 31 ns typical reverse recovery time at dIF/dt = −200 A/µs and Tj = 25 °C. It serves as a low-loss freewheeling and polarity protection diode in high-frequency inverters and transistor base-drive circuits.
For engineers reviewing the STTH60R04W datasheet, STTH60R04W pinout, STTH60R04W application, or STTH60R04W equivalent, key selection criteria include its 0.95 V typical forward voltage at 150 °C, softness factor of 0.4, junction-to-case thermal resistance of 0.7 °C/W, and DO-247 through-hole package suitability for high-pulsed-current switching.
Technical Context
This diode employs Pt-doping planar junction technology to achieve ultrafast recovery with controlled softness (S = 0.4), minimizing EMI and voltage overshoot during commutation. Its dynamic behavior is characterized under high dIF/dt conditions (up to −200 A/µs) and elevated junction temperatures (up to 175 °C).
Thermal performance is optimized for conduction-cooled mounting: Rth(j–c) = 0.7 °C/W enables sustained 60 A average current at Tc = 110 °C, while surge capability supports IFSM = 650 A (10 ms sinusoidal) and IFRM = 375 A (5 µs square wave, 1 kHz).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum repetitive reverse blocking voltage; defines safe operating range in DC-link and freewheeling positions |
| IF(AV) | 60 A at Tc = 110 °C - continuous forward current rating under heatsink-controlled thermal conditions |
| trr (typ) | 31 ns at IF = 1 A, dIF/dt = −200 A/µs, VR = 30 V, Tj = 25 °C - enables >1 MHz switching in resonant converters |
| VF (typ) | 0.95 V at IF = 60 A, Tj = 150 °C - low conduction loss supporting high-efficiency low-voltage (<48 V) power stages |
| S (Softness) | 0.4 at IF = 60 A, dIF/dt = −200 A/µs, VR = 320 V, Tj = 125 °C - reduces voltage ringing and EMI during turn-off |
| Rth(j–c) | 0.7 °C/W - allows direct mounting to heatsink without thermal interface pads for compact thermal design |
| Tj max | 175 °C - supports operation in high-ambient industrial environments with derated current |
Pinout & Package
STTH60R04W is housed in a DO-247 through-hole package with an isolated metal tab (cathode-connected case). The device has two terminals: Anode (lead) and Cathode (case/tab), enabling low-inductance, high-current PCB mounting with direct thermal path to heatsink.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to switching node (e.g., MOSFET drain); must withstand high dIF/dt transients |
| Cathode (Case/Tab) | Forward current exit & thermal path | Electrically tied to cathode; provides low-impedance thermal conduction to heatsink (Rth(j–c) = 0.7 °C/W) |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery | 31 ns trr at high dIF/dt (−200 A/µs) ensures minimal switching loss in >500 kHz SMPS topologies |
| Soft recovery characteristic | S = 0.4 suppresses voltage overshoot and reduces snubber requirements in hard-switched converters |
| High junction temperature rating | 175 °C max Tj enables reliable operation in sealed enclosures or high-ambient industrial settings |
| Low forward voltage | 0.95 V VF at 60 A / 150 °C lowers conduction loss by ~15% vs. standard fast diodes in 12–48 V systems |
| Robust surge capability | 650 A IFSM (10 ms) supports motor-start and inductive load transient immunity without derating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast recovery diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS MUR6040CT | TO-247 package, dual common-cathode configuration; trr = 35 ns (typ), VF = 1.15 V @ 60 A / 125 °C | Requires dual-diode layout; higher VF increases conduction loss in high-duty-cycle applications | Select when dual-diode topology or legacy TO-247 footprint is required; verify thermal interface due to higher Rth(j–c) |
| Vishay VS-60EWH04 | DO-247 package, same pinout; trr = 30 ns (typ), VF = 0.92 V @ 60 A / 150 °C, but Tj max = 150 °C | Limited to lower ambient or derated current in high-temperature environments | Prefer for lowest VF where junction temperature stays ≤150 °C; avoid in sealed 70 °C+ enclosures |
Compared with MUR6040CT and VS-60EWH04, STTH60R04W offers superior thermal robustness (175 °C Tj) and balanced softness (S = 0.4), making it optimal for industrial inverters requiring long-term reliability under thermal stress without sacrificing EMI control.

FAQ
What is the maximum recommended mounting torque for the STTH60R04W DO-247 package?
The manufacturer specifies a recommended torque value of 0.8 Nm and a maximum torque of 1.0 Nm for the STTH60R04W's mounting screw. Exceeding 1.0 Nm risks mechanical damage to the epoxy body or internal bond wires, potentially compromising thermal contact or reverse leakage performance. Always use calibrated torque tools during heatsink assembly.
Does STTH60R04W support lead-free soldering processes?
Yes - STTH60R04W is supplied in an ECOPACK®-compliant DO-247 package with lead-free second-level interconnects, meeting JEDEC JESD97 standards. Its maximum soldering temperature rating is documented on the inner box label, and it supports standard Pb-free reflow profiles (peak ≤260 °C, <60 s above 217 °C) without degradation of trr or VF parameters.
How does junction temperature affect reverse recovery time in STTH60R04W?
trr decreases with rising junction temperature: at Tj = 125 °C, trr drops to ~35 ns (vs. 31 ns at 25 °C) under identical test conditions (IF = 1 A, dIF/dt = −200 A/µs, VR = 30 V). This reduction improves high-frequency efficiency but requires verification of softness factor stability, which remains ≥0.35 up to 175 °C per Figure 7.
Can STTH60R04W be used in parallel configurations for higher current handling?
Parallel operation is not recommended without individual current-sharing resistors or matched thermal mounting. The device exhibits positive temperature coefficient for VF, but minor process variations in trr and softness can cause dynamic current imbalance during switching transients. For >60 A average current, ST recommends using multiple discrete units with symmetrical layout and independent thermal paths instead of direct paralleling.
