Product details
Overview
HER1602PTH from Taiwan Semiconductor is a high-efficiency, AEC-Q101-qualified dual-die ultrafast recovery rectifier in TO-247AD (TO-3P) package, rated for 16 A average forward current, 100 V repetitive peak reverse voltage, and 200 A non-repetitive surge current - used in automotive-grade DC/DC converters and snubber circuits.
For engineers reviewing the HER1602PTH datasheet, HER1602PTH pinout, HER1602PTH application, or HER1602PTH equivalent, key selection criteria include its 100 V VRRM, 1.0 V max forward voltage at 8 A/25°C, 50 ns reverse recovery time, dual-die configuration, and AEC-Q101 qualification for under-hood power conversion.
Technical Context
This device integrates two independent ultrafast recovery diodes in a single TO-247AD package, enabling compact dual-path rectification or freewheeling. Its low thermal resistance and matte tin-plated leads support high-power dissipation and reliable solderability per J-STD-002.
The HER1602PTH operates with junction temperature range of –55°C to +150°C and exhibits 10 µA max reverse leakage at 25°C and 500 µA at 125°C, making it suitable for thermally demanding switching-mode applications where efficiency and stability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum blocking voltage before avalanche; defines safe operating range in 12–48 V automotive bus systems |
| IF | 16 A - continuous average forward current; supports high-current output stages without forced cooling |
| IFSM | 200 A - peak non-repetitive surge rating; withstands inrush and fault transients in SMPS and inverters |
| VF @ 8 A, 25°C | ≤1.0 V - low conduction loss; reduces power dissipation by ~15% vs. standard FRD counterparts |
| trr | ≤50 ns - ultrafast recovery; minimizes switching losses and EMI in >100 kHz converters |
| Junction Temp | –55°C to +150°C - wide thermal envelope enables under-hood deployment without derating |
| Package | TO-247AD (TO-3P) - industry-standard high-power outline with isolated mounting hole and 5.6 g mass |
Pinout & Package
TO-247AD (TO-3P) package with three terminals: Anode 1, Cathode (common), Anode 2 - dual-anode, single-cathode configuration optimized for center-tapped transformer rectification and synchronous freewheeling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Input node for first diode path | Accepts positive half-cycle input in dual-phase rectifier topologies |
| Cathode | Common output node | Provides shared return path; electrically ties both diodes' cathodes internally |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1602D | Same 100 V VRRM, 16 A IF, but TO-247AC package; trr = 45 ns, VF = 1.05 V @ 8 A | No AEC-Q101 qualification; UL recognition not specified | Preferred for cost-sensitive industrial SMPS where automotive qualification is unnecessary |
| IXYS MUR1620CT | 200 V VRRM, same TO-247AD package; trr = 60 ns, VF = 1.15 V @ 8 A | Higher voltage rating trades off lower efficiency at 100 V systems | Selected when system-level overvoltage margin requires ≥200 V blocking capability |
Compared with STTH1602D and IXYS MUR1620CT, the HER1602PTH delivers tighter VF tolerance, AEC-Q101 compliance, and optimized 100 V rating - making it the preferred choice for automotive 12/48 V power conversion where reliability and thermal performance are prioritized over raw voltage headroom.

FAQ
What is the maximum junction temperature rating for HER1602PTH?
The HER1602PTH has a maximum junction temperature (TJMAX) of +150°C, verified per JEDEC JESD22-A108. This rating allows uninterrupted operation in under-hood automotive environments and high-ambient industrial settings without thermal derating below 16 A IF. The HER1602PTH maintains stable electrical parameters across its full –55°C to +150°C junction range.
Is HER1602PTH pin-compatible with other devices in the HER160xPT family?
Yes - all HER160xPT and HER160xPTH variants share identical TO-247AD (TO-3P) mechanical footprint, pinout, and terminal assignment (Anode 1 / Cathode / Anode 2). Voltage ratings differ only in internal die design; PCB layout remains unchanged across the HER1601PTH to HER1608PTH series.
Does HER1602PTH require heatsinking in typical 16 A applications?
HER1602PTH thermal resistance (RθJC) is 0.8°C/W. At 16 A and 1.0 V forward drop, power dissipation is ~16 W; with a 25°C ambient and 50°C case rise limit, a heatsink with ≤3.1°C/W total thermal resistance is required. Mounting torque must not exceed 1.13 N·m to maintain thermal interface integrity.
What does the "H" suffix in HER1602PTH signify?
The "H" in HER1602PTH indicates full AEC-Q101 qualification per Rev G, including stress testing for HTSL, TC, AC/DC life test, and ESD. It also denotes halogen-free construction compliant with IEC 61249-2-21 and RoHS compliance - distinguishing it from non-H variants like HER1602PT.
How does HER1602PTH's reverse recovery time compare to standard FRDs?
HER1602PTH achieves ≤50 ns reverse recovery time (trr) at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A - approximately 40–60% faster than legacy FRDs (e.g., 100–150 ns). This directly reduces switching losses and EMI generation in high-frequency converters, improving overall system efficiency and EMC compliance.
