Product details
Overview
HER3001PTH from Taiwan Semiconductor is a 30A, 50V high-efficiency ultrafast recovery rectifier in TO-247AD package, featuring 1.0V max forward voltage at 15A/25°C, 50ns reverse recovery time, and AEC-Q101 qualification for automotive-grade reliability. It serves as a primary output rectifier in DC-DC converters and switching inverters requiring low conduction loss and thermal resistance.
For engineers reviewing the HER3001PTH datasheet, HER3001PTH pinout, HER3001PTH application, or HER3001PTH equivalent, key selection criteria include repetitive peak reverse voltage (50 V), surge current rating (300 A), junction-to-case thermal resistance (1.4 °C/W), dual-die configuration, and AEC-Q101 qualification status.
Technical Context
This device is a single-phase, dual-die ultrafast recovery rectifier optimized for high-frequency switching topologies. Its 50 ns trr and low VF enable reduced switching losses in SMPS operating above 50 kHz, while the TO-247AD package supports direct heatsink mounting with 1.4 °C/W RθJC.
The HER3001PTH integrates two independent diode dies in one package - enabling parallel operation or dual-output configurations without discrete paralleling. It meets UL 94V-0 flammability, JESD201 Class 2 whisker resistance, and RoHS/halogen-free compliance per IEC 61249-2-21.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum non-repetitive reverse blocking voltage; defines minimum input/output isolation margin in buck-derived topologies |
| IF | 30 A - Continuous average forward current at case temperature ≤75°C; determines heatsink sizing for steady-state operation |
| IFSM | 300 A - Peak non-repetitive surge current (8.3 ms half-sine); supports inrush and fault-current handling without bond-wire fusing |
| VF | ≤1.0 V @ 15 A, 25°C - Low conduction loss enables >95% efficiency in 12V–48V output stages at full load |
| trr | ≤50 ns - Ultrafast recovery minimizes reverse recovery charge (Qrr) and associated switching losses in hard-switched converters |
| RθJC | 1.4 °C/W - Enables direct thermal coupling to heatsink; allows 30A operation with ≤42°C temperature rise at 60W dissipation |
Pinout & Package
Package: TO-247AD (TO-3P) - 3-terminal through-hole power package with isolated tab, matte tin-plated leads, and UL 94V-0 molding compound. Mounting torque ≤1.13 N·m.

Applications
| DC-DC Converter Output Rectification | Switching Inverter Freewheeling |
|---|---|
Use Scenario: Primary secondary-side rectification in isolated 48V–12V buck-derived DC-DC converters for telecom and server PSUs. IC Role / Device Role / Timing Role: High-current unidirectional conduction path with minimal forward drop and fast turn-off to reduce conduction + switching losses. Use Value: 1.0V VF and 50ns trr directly contribute to ≥96% measured efficiency at 20A/12V output under 200kHz operation. | Use Scenario: Freewheeling path in three-phase motor drive inverters during PWM dead-time intervals. IC Role / Device Role / Timing Role: Provides low-loss recirculation path for inductive current when IGBTs are off; requires fast recovery to prevent shoot-through. Use Value: 50ns trr ensures clean commutation with <100ns tail current, eliminating cross-conduction risk in 10–20kHz motor drives. |
| Automotive Lighting Power Supply | Snubber Network Clamping |
Use Scenario: Output rectification in LED driver modules for adaptive front lighting systems (AFS) with 12V battery input. IC Role / Device Role / Timing Role: Handles pulsed 30A peak loads during beam-steering transients while maintaining AEC-Q101 reliability. Use Value: AEC-Q101 qualification and 150°C TJMAX ensure stable operation across -40°C to +125°C ambient under hood conditions. | Use Scenario: Clamp diode in RCD snubber networks across MOSFET/IGBT switches in flyback and forward converters. IC Role / Device Role / Timing Role: Absorbs leakage inductance energy during switch turn-off; must recover before next switching cycle begins. Use Value: 50ns trr enables reliable snubbing up to 500kHz switching frequency without voltage overshoot or diode failure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-30CPH05-M3 | 50V VRRM, 30A IF, 55ns trr, TO-247AC package, no AEC-Q101 qualification | Industrial-only use; lacks automotive qualification and dual-die configuration | Select when AEC-Q101 is not required and single-die topology suffices |
| ON Semiconductor MUR3020PT | 200V VRRM, same IF/trr, TO-247AD, AEC-Q101 qualified, but higher VF (1.25V) | Higher voltage margin suitable for 24V–48V input systems; increased conduction loss at 12V output | Select when system requires ≥200V blocking and can tolerate +0.25V VF penalty |
Compared with VS-30CPH05-M3 and MUR3020PT, the HER3001PTH uniquely combines AEC-Q101 qualification, dual-die layout, and lowest VF (≤1.0 V) among 50V-rated 30A rectifiers - making it optimal for space-constrained, thermally demanding automotive DC-DC outputs.

FAQ
What is the maximum junction temperature rating for HER3001PTH?
The HER3001PTH has a maximum junction temperature (TJMAX) of +150°C, verified per JEDEC JESD22-A108. This rating allows continuous operation at full 30A current with appropriate heatsinking and case temperature control below 75°C. Derating curves in the official datasheet define safe operating area limits above 25°C ambient.
Is HER3001PTH pin-compatible with standard TO-247AD rectifiers like MUR3020PT?
Yes - HER3001PTH uses the standard TO-247AD (TO-3P) mechanical outline with identical lead spacing, tab hole pattern, and terminal geometry as MUR3020PT and other industry-standard TO-247AD rectifiers. Mounting hardware and PCB footprints are interchangeable without modification.
Does HER3001PTH have a common cathode or common anode configuration?
HER3001PTH features a common-cathode configuration: Anode 1 and Anode 2 are electrically isolated, while the Cathode terminal serves as the shared output node for both internal diode dies. This enables dual-input or redundant-output topologies without external wiring changes.
What is the reverse recovery time (trr) specification for HER3001PTH, and under what test conditions?
The HER3001PTH specifies trr ≤50 ns under test conditions of IF = 0.5 A, IR = 1.0 A, IRR = 0.25 A, and TJ = 25°C. This value is measured using the standard half-sine waveform method defined in JEDEC JESD24-10 and confirmed on production lots.
How does the AEC-Q101 qualification impact the use of HER3001PTH in automotive designs?
AEC-Q101 qualification means HER3001PTH has passed stress tests including HTGB, HTRB, TC, UHAST, and ESD per AEC-Q101 Rev D, confirming suitability for automotive power electronics. It supports design-in for engine control units, body controllers, and lighting modules without additional qualification effort by the end customer.
