Product details
Overview
HER1602PT from Taiwan Semiconductor is a 16A, 100V high-efficiency ultrafast recovery rectifier diode in TO-247AD package, featuring 1.0V max forward voltage at 8A/25°C, 50ns reverse recovery time, and AEC-Q101 qualification for automotive-grade reliability - used in switching-mode DC-DC converters and snubber circuits.
For engineers reviewing the HER1602PT datasheet, HER1602PT pinout, HER1602PT application, or HER1602PT equivalent, key selection criteria include VRRM = 100V, IF = 16A, trr = 50ns, low thermal resistance, and dual-die TO-247AD mechanical construction suitable for high-power industrial and automotive power conversion.
Technical Context
The HER1602PT integrates two high-efficiency epitaxial rectifier dies in a single TO-247AD package, optimized for fast switching with 50ns reverse recovery time and low conduction loss (VF ≤ 1.0V @ 8A). Its 100V repetitive peak reverse voltage and 200A surge rating support robust operation in hard-switched topologies.
Designed for high-reliability applications, it meets AEC-Q101 stress testing requirements, UL 94V-0 molding compound, JESD201 Class 2 whisker resistance, and operates across -55°C to +150°C junction temperature range - enabling use in under-hood automotive power supplies and industrial inverters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum non-repetitive reverse blocking voltage; defines safe operating limit in flyback or freewheeling configurations |
| IF | 16 A - Continuous average forward current; supports high-power DC-DC stages without forced air cooling |
| trr | 50 ns - Ultrafast reverse recovery time; minimizes switching losses in 100–500 kHz SMPS designs |
| VF | ≤1.0 V @ 8A, 25°C - Low forward voltage drop; reduces conduction loss and thermal load in high-current paths |
| IFSM | 200 A - Peak non-repetitive surge current; withstands inrush and fault transients in motor drives and UPS systems |
| TJ max | +150 °C - Maximum junction temperature; enables compact heatsink design in space-constrained enclosures |
Pinout & Package
Package: TO-247AD (TO-3P) - 3-terminal through-hole package with isolated tab, matte tin-plated leads, UL 94V-0 molding compound, and 5.6g mass. Mounting torque ≤1.13 N·m. Polarity marked on device body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry | Connected to input/high-side node in rectification path; requires low-inductance layout for fast switching |
| Cathode (Lead 2) | Forward current exit | Common output node for dual-die configuration; ties to ground or return rail in center-tapped topologies |
| Tab (Anode-connected) | Thermal & electrical connection | Electrically tied to Anode; must be insulated from chassis unless circuit design requires common-anode mounting |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive power modules requiring extended temperature cycling, humidity, and mechanical shock compliance |
| Ultrafast trr = 50 ns | Enables >300 kHz switching in PFC and LLC resonant converters while limiting EMI generation |
| Dual-die TO-247AD construction | Provides redundancy and thermal symmetry; improves current sharing and thermal derating vs. single-die alternatives |
| Low VF ≤ 1.0 V @ 8A | Reduces power dissipation by ~15% compared to standard FRDs at same current, lowering heatsink requirements |
Applications
| DC-DC Converter | Snubber Circuit |
|---|---|
Use Scenario: Secondary-side synchronous rectification in isolated 48V-to-12V telecom DC-DC modules.

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 = 100V, trr = 45ns, VF = 1.05V @ 8A, TO-247 package | No AEC-Q101 qualification; lower surge rating (175A IFSM) | Preferred where ultra-low trr is critical and automotive qualification is not required |
| IXYS MUR1620CT | VRRM = 200V, trr = 60ns, VF = 1.15V @ 8A, TO-220AB package | Higher VRRM, slower recovery, smaller package with higher thermal resistance | Selected when 200V blocking is needed and board space limits TO-247 footprint |
Compared with STTH1602D and IXYS MUR1620CT, the HER1602PT delivers AEC-Q101 compliance, superior surge robustness (200A), and lower forward voltage in the same TO-247AD form factor - making it optimal for automotive and high-reliability industrial rectification where thermal and transient margins are constrained.

FAQ
What is the maximum junction temperature rating for HER1602PT?
The HER1602PT has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings in the official TSC datasheet (Version H2103). This allows operation in high-ambient environments such as under-hood automotive locations or enclosed industrial power supplies. Derating curves confirm usable current capacity down to 10A at 125°C case temperature. HER1602PT must be mounted with thermally conductive interface material and appropriate heatsinking to maintain this limit.
Is HER1602PT pin-compatible with other parts in the HER160xPT family?
Yes, all HER160xPT devices - including HER1601PT through HER1608PT - share identical TO-247AD (TO-3P) mechanical dimensions, pinout, and terminal assignments. The only functional difference is VRRM, ranging from 50V to 1000V. HER1602PT uses the same Anode–Cathode–Tab configuration and mounting torque specification (≤1.13 N·m), enabling direct substitution within the same voltage class design constraints.
Does HER1602PT have AEC-Q101 qualification?
Yes, HER1602PT is explicitly listed as AEC-Q101 qualified in the official Taiwan Semiconductor datasheet (Version H2103), with qualification noted under FEATURES and ORDERING INFORMATION (HER1602PTH variant). This includes stress testing for temperature cycling, high-temperature operating life, unbiased highly accelerated stress, and mechanical shock - confirming suitability for automotive powertrain and body electronics applications.
What is the reverse recovery time (trr) of HER1602PT and how is it measured?
The HER1602PT has a typical reverse recovery time (trr) of 50 ns, specified under ELECTRICAL SPECIFICATIONS at IF = 0.5A, IR = 1.0A, and Irr = 0.25A. This value is measured using the standard double-pulse test method defined in JEDEC standards, with conditions matching Fig.6 test circuit in the datasheet. It applies to HER1601PT through HER1605PT variants and reflects ultrafast soft-recovery behavior critical for EMI-sensitive SMPS designs.
Can HER1602PT be used in surface-mount designs?
No, HER1602PT is exclusively offered in the through-hole TO-247AD (TO-3P) package and is not available in any surface-mount variant. Its thermal and mechanical design - including isolated metal tab, lead pitch, and mounting torque requirement - mandates PCB through-hole mounting with heatsink attachment. For SMT alternatives, engineers should evaluate discrete SMD Schottky or fast recovery diodes with compatible ratings, but none match the HER1602PT's combination of 16A current, 100V VRRM, and AEC-Q101 qualification in SMT form.
