Product details
Overview
HERF1602G from Taiwan Semiconductor is a 16 A, 100 V repetitive peak reverse voltage (VRRM) high-efficiency ultrafast rectifier in ITO-220AB package, featuring 125 A surge capability (IFSM), 1.0 V typical forward voltage at 8 A/25°C, and 50 ns reverse recovery time - deployed in DC-DC converters and switching-mode inverters.
For engineers reviewing the HERF1602G datasheet, HERF1602G pinout, HERF1602G application, or HERF1602G equivalent, key selection criteria include its 100 V VRRM, dual-die configuration, UL Recognized status (E-326243), AEC-Q101 qualification option (HERF1602GH), and thermal resistance of 1.5 °C/W.
Technical Context
This device is a single-phase, dual-die ultrafast recovery rectifier optimized for high-frequency switching topologies. It delivers low conduction loss via 1.0 V VF (typ, 8 A, 25°C) and fast switching with 50 ns trr, enabling efficient operation in hard-switched SMPS and freewheeling paths where di/dt stress and reverse recovery charge are critical.
The ITO-220AB package provides robust thermal performance (RθJC = 1.5 °C/W) and mechanical reliability per JESD201 Class 2 whisker testing. Polarity is marked on body; terminals are matte tin-plated and J-STD-002 solderable.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1602D | 16 A, 200 V VRRM, 1.15 V VF (typ), 60 ns trr, TO-220AC package (non-isolated tab) | Higher VRRM margin but higher VF and slower recovery; requires isolation sleeve for heatsink mounting | Select when 200 V blocking is required and thermal design accommodates higher conduction loss |
| ON Semi MUR1620CT | 16 A, 200 V VRRM, 1.7 V VF (max), 75 ns trr, TO-220AB package (isolated tab) | Slower recovery and higher forward drop; lower cost but reduced efficiency at high frequency | Choose for cost-sensitive industrial supplies where 100–200 kHz operation dominates and thermal headroom exists |
Compared with STTH1602D and MUR1620CT, HERF1602G offers superior high-frequency efficiency (50 ns trr, 1.0 V VF) and certified isolation (ITO-220AB), making it optimal for compact, thermally constrained 100 V SMPS designs requiring automotive-grade variants.

FAQ
What is the maximum junction temperature rating for HERF1602G?
The HERF1602G has a maximum junction temperature (TJ) rating of +150 °C, with a minimum of -55 °C. This wide operating range supports deployment in under-hood automotive environments and high-ambient industrial enclosures. The device's thermal resistance (RθJC = 1.5 °C/W) ensures predictable derating up to this limit when mounted on an appropriate heatsink. HERF1602G must not exceed 150 °C under steady-state or transient conditions to maintain reliability and parametric integrity.
Is HERF1602G pin-compatible with other devices in the HERF160xG family?
Yes, all HERF160xG devices share identical ITO-220AB packaging, pinout, and thermal/mechanical footprint - including HERF1602G. Voltage ratings differ across the family (50–1000 V), but electrical connections, mounting torque (0.56 N·m), and polarity marking remain consistent. This allows board-level voltage scalability without layout changes. HERF1602G uses the same Anode 1 / Cathode / Anode 2 terminal assignment as HERF1601G through HERF1608G.
Does HERF1602G have AEC-Q101 qualification?
The base HERF1602G is not AEC-Q101 qualified, but the HERF1602GH variant is fully AEC-Q101 qualified and marked with "H" suffix. Both share identical electrical specs and package; only HERF1602GH undergoes extended stress testing per AEC-Q101 Rev D. For automotive applications requiring qualification evidence, HERF1602GH must be specified. HERF1602G remains suitable for industrial and commercial use where AEC-Q101 is not mandated.
What is the reverse recovery time (trr) specification for HERF1602G?
The HERF1602G has a maximum reverse recovery time (trr) of 50 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This ultrafast value is confirmed in the official TSC datasheet (Version I2105) and applies specifically to HERF1601G–HERF1605G variants. The 50 ns trr enables efficient operation in switching power supplies operating above 200 kHz, minimizing switching loss and EMI generation compared to standard fast recovery diodes.
How does the dual-die configuration of HERF1602G impact circuit design?
The HERF1602G integrates two independent rectifier dies in a common-cathode ITO-220AB package, with separate Anode 1 and Anode 2 terminals sharing one Cathode. This enables dual-output rectification (e.g., ±12 V rails) or interleaved operation without external paralleling. It reduces PCB area versus discrete solutions and eliminates mismatch-induced current imbalance. HERF1602G's dual-die architecture is electrically isolated between anodes, supporting asymmetric load distribution while maintaining thermal coupling for uniform junction temperature tracking.
