Product details
Overview
HER1601PT from Taiwan Semiconductor is a 16A, 50V high-efficiency ultrafast recovery rectifier in TO-247AD (TO-3P) package, featuring 1.0V max forward voltage at 8A/25°C, 50ns reverse recovery time, and dual-die construction for high-current DC–DC and switching-mode power conversion.
For engineers reviewing the HER1601PT datasheet, HER1601PT pinout, HER1601PT application, or HER1601PT equivalent, key selection criteria include VRRM = 50V, IF = 16A continuous, trr = 50ns, low thermal resistance, and AEC-Q101 qualification availability - critical for automotive-grade power supply design and snubber circuits.
Technical Context
The HER1601PT implements an ultrafast recovery silicon rectifier structure optimized for high-frequency switching applications up to several hundred kHz. Its dual-die configuration enables parallel current handling while maintaining tight thermal coupling and matched electrical characteristics across both dies.
It operates with junction temperature range of –55°C to +150°C, supports 200A non-repetitive surge current (8.3ms half-sine), and achieves low power loss via 1.0V typical forward voltage at rated current - directly enabling higher efficiency in flyback, forward, and LLC resonant converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - maximum repetitive reverse voltage; defines safe blocking capability in 12–24V input systems |
| IF | 16 A - continuous forward current rating; supports high-power output stages without forced air cooling |
| trr | 50 ns - ultrafast reverse recovery time; minimizes switching losses in >100kHz SMPS designs |
| VF | 1.0 V max @ 8A, 25°C - low conduction loss enabling >95% efficiency in mid-power DC–DC converters |
| CJ | 85 pF - junction capacitance per diode; reduces capacitive turn-on loss and EMI in hard-switched topologies |
| TJ max | +150°C - extended junction temperature rating allows operation in compact, thermally constrained enclosures |
Pinout & Package
HER1601PT uses the TO-247AD (TO-3P) package: isolated metal tab (cathode), three leads - anode, cathode, and auxiliary cathode connection for dual-die configuration. Mounting torque ≤1.13 N·m; matte tin-plated leads compliant with J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Input current entry point | Connects to switching node or transformer secondary; carries full load current during conduction |
| Cathode (Lead 2) | Output current exit point | Common cathode terminal shared by both internal dies; connects to output rail or filter capacitor |
| Metal Tab | Thermal & electrical cathode | Electrically tied to cathode; provides primary heat path to heatsink; requires insulating washer if mounted to grounded chassis |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery (trr = 50 ns) | Enables efficient operation in high-frequency (>200 kHz) switch-mode power supplies with minimal switching loss |
| Dual-die configuration | Provides redundancy and current sharing; improves thermal distribution and reliability under transient overloads |
| AEC-Q101 qualified version available | Validated for automotive under-hood environments including temperature cycling, humidity, and mechanical shock |
| UL Recognized (E-326243) | Meets safety requirements for end-equipment certification in industrial and consumer power systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1602D | VRRM = 200V, trr = 35ns, single-die TO-247 | Better suited for 200V bus systems; faster but lower voltage margin than HER1601PT | Select when higher VRRM headroom and faster recovery are prioritized over cost and dual-die robustness |
| IXYS MUR1620CT | VRRM = 200V, trr = 35ns, dual common-cathode TO-220AC | Lower power handling (TJ max = 175°C but IF derated to 8A at 100°C); smaller package limits thermal performance | Choose only for space-constrained, lower-power (<100W) designs where TO-220 footprint is mandatory |
Compared with STTH1602D and MUR1620CT, HER1601PT offers optimal balance of 50V rating, 16A current capacity, dual-die reliability, and TO-247AD thermal performance - making it preferred for automotive and industrial 12–48V systems requiring long-term stability under thermal cycling.

FAQ
What is the maximum junction temperature rating for HER1601PT?
The HER1601PT has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table. This allows reliable operation in thermally demanding environments such as enclosed LED drivers or automotive under-hood power modules. Derating curves confirm usable current capacity down to 10A at 125°C case temperature. HER1601PT must be mounted to a heatsink meeting thermal resistance requirements specified in its datasheet to sustain this rating.
Is HER1601PT pin-compatible with other parts in the HER160xPT family?
No - HER1601PT shares the same TO-247AD (TO-3P) package and pinout with all HER160xPT variants, but voltage ratings differ: HER1601PT is rated for 50V VRRM, while HER1602PT is 100V, HER1603PT is 200V, etc. Electrical substitution requires verification of reverse voltage margin and thermal performance. HER1601PT cannot replace higher-voltage variants without risk of breakdown under reverse bias.
Does HER1601PT have AEC-Q101 qualification?
HER1601PT itself is not automatically AEC-Q101 qualified; however, the AEC-Q101-qualified version is offered as HER1601PTH (with 'H' suffix). The base HER1601PT meets RoHS, halogen-free, and UL recognition requirements, but automotive qualification requires explicit ordering of the 'H' variant. Always verify part marking and packaging code before use in automotive applications.
What is the reverse recovery time (trr) of HER1601PT and how is it measured?
HER1601PT has a maximum reverse recovery time (trr) of 50 ns, measured under IF = 0.5A, IR = 1.0A, and Irr = 0.25A per the datasheet test condition. This ultrafast value reflects optimized carrier lifetime control in the epitaxial layer. HER1601PT's trr is confirmed across production lots using standardized double-pulse test circuits per JEDEC standards - critical for minimizing switching loss in high-frequency converters.
Can HER1601PT be used in freewheeling applications with inductive loads?
Yes - HER1601PT is explicitly recommended for freewheeling applications per its official applications list. Its 50ns trr, 200A IFSM, and dual-die construction enable rapid current commutation and robust surge handling during inductive kickback events. When used as a freewheeling diode across relay coils or motor windings, HER1601PT suppresses voltage spikes effectively while maintaining low forward drop and thermal stability.
