Product details
Overview
HER1602G from Taiwan Semiconductor is a high-efficiency, AEC-Q101-qualified dual-die ultrafast recovery rectifier in TO-220AB package, rated for 100 V repetitive peak reverse voltage (VRRM), 16 A average forward current (IF), and 125 A non-repetitive surge current (IFSM). It delivers low forward voltage (1.0 V at 8 A, 25°C) and fast reverse recovery (50 ns), making it suitable for high-frequency switching power supplies in automotive and industrial DC–DC converters.
For engineers reviewing the HER1602G datasheet, HER1602G pinout, HER1602G application, or HER1602G equivalent, key selection criteria include its 100 V VRRM, dual-die TO-220AB configuration, 1.0 V forward drop at 8 A, 50 ns trr, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
The HER1602G integrates two independent high-efficiency silicon rectifier dies in a single TO-220AB package with common-cathode configuration. Its ultrafast recovery (trr ≤ 50 ns) and low junction capacitance (80 pF at 4 V) minimize switching losses in high-frequency topologies.
Thermally, it features a junction-to-case thermal resistance of 1.5 °C/W and operates across –55°C to +150°C junction temperature range, supporting robust performance in thermally constrained environments without derating below 16 A up to 75°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating limit in flyback or freewheeling paths. |
| IF | 16 A - Continuous average forward current; supports high-power DC–DC stages without forced air cooling. |
| IFSM | 125 A - Peak non-repetitive surge current (8.3 ms half-sine); withstands inrush and fault transients in SMPS inputs. |
| VF | 1.0 V @ 8 A, 25°C - Low conduction loss improves efficiency and reduces thermal stress in high-current paths. |
| trr | 50 ns - Ultrafast reverse recovery time minimizes switching losses and EMI in >100 kHz converters. |
| RθJC | 1.5 °C/W - Enables direct heatsink mounting for thermal management in space-constrained power modules. |
Pinout & Package
HER1602G uses the standard TO-220AB package with three leads: Anode 1, Cathode (common), Anode 2 - configured as a dual common-cathode rectifier. The case is electrically isolated and designed for mechanical mounting via the central tab.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Lead 1 (left) | Anode 1 | Input terminal for first rectifier die; connects to AC or switching node in dual-phase or center-tapped configurations. |
| Lead 2 (center) | Cathode (common) | Shared output node for both dies; serves as positive DC bus connection in full-wave or parallel-output designs. |
| Lead 3 (right) | Anode 2 | Input terminal for second rectifier die; enables symmetrical current sharing and balanced thermal distribution. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood applications including engine control units and ADAS power supplies. |
| Ultrafast recovery (trr ≤ 50 ns) | Reduces switching loss and ringing in high-frequency synchronous rectification and resonant topologies. |
| Dual common-cathode die | Enables compact full-wave bridge replacement or interleaved output rectification without external wiring. |
| Low VF (1.0 V @ 8 A) | Lowers conduction loss by ~15% vs. standard FRD equivalents, improving system efficiency at 12–48 V output rails. |
Applications
| Automotive DC–DC Converters | Industrial Switch-Mode Power Supplies |
|---|---|
Use Scenario: 12 V to 5 V/3.3 V buck converter in vehicle infotainment ECUs with transient-heavy load profiles. IC Role / Device Role / Timing Role: HER1602G serves as synchronous rectifier or freewheeling diode in high-side switch topology, handling bidirectional current during dead-time intervals. Use Value: Its 50 ns trr and 1.0 V VF reduce switching loss and thermal rise, enabling smaller heatsinks and higher power density in AEC-Q101-compliant designs. | Use Scenario: Output rectification stage in 48 V telecom rectifier modules delivering up to 200 W continuous power. IC Role / Device Role / Timing Role: HER1602G functions as dual-path output rectifier, splitting current between two anodes while sharing a common cathode rail to the filter capacitor bank. Use Value: Dual-die integration eliminates interconnect inductance and matching errors, improving cross-regulation and dynamic response under step-load conditions. |
| Freewheeling in Motor Drives | UPS Inverter Output Stage |
Use Scenario: Freewheeling path for brushed DC motor drivers in HVAC actuators, where rapid current decay prevents back-EMF damage. IC Role / Device Role / Timing Role: HER1602G provides low-loss return path during MOSFET off-time, clamping inductive kickback with minimal voltage overshoot. Use Value: 125 A IFSM rating ensures reliable operation during stall events, while 1.5 °C/W RθJC allows direct heatsink coupling for sustained 16 A freewheeling duty. | Use Scenario: Output stage of online UPS inverters converting 380 V DC bus to 230 V AC, requiring low-loss, high-reliability rectification during battery backup mode. IC Role / Device Role / Timing Role: HER1602G operates as line-commutated rectifier in the inverter's anti-parallel path, conducting reverse current during zero-crossing transitions. Use Value: 100 V VRRM and 150°C TJMAX support operation in high-temperature enclosures, while RoHS/halogen-free compliance meets global safety standards. |
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 VRRM (100 V), IF (16 A), but trr = 35 ns (faster), VF = 1.15 V (higher), TO-220AC package (single-diode). | Single-die construction requires external paralleling for dual-path use; lacks common-cathode integration. | Select when fastest recovery is critical and layout allows discrete placement; not drop-in for HER1602G's dual-anode footprint. |
| ON Semiconductor MUR1620CT | VRRM = 200 V (higher), same IF/IFSM, trr = 60 ns (slower), VF = 1.1 V, TO-220AB dual common-cathode. | Higher voltage rating suits 24–48 V systems with elevated transient margins; slightly slower recovery increases switching loss above 200 kHz. | Prefer for designs needing headroom against voltage spikes; verify thermal design due to higher VF and trr. |
Compared with STTH1602D and MUR1620CT, HER1602G offers optimal balance of low VF (1.0 V), ultrafast trr (50 ns), and integrated dual-anode/common-cathode topology - enabling compact, efficient, and AEC-Q101-compliant rectification without external component duplication.

FAQ
What is the maximum junction temperature rating for HER1602G?
The HER1602G has a maximum junction temperature (TJMAX) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet (Version J2104). This rating enables operation in under-hood automotive environments and high-ambient industrial settings without derating until case temperatures exceed 100°C. Thermal design must maintain RθJC ≤ 1.5 °C/W to sustain full 16 A current at TJ = 150°C.
Is HER1602G pin-compatible with other parts in the HER160xG family?
Yes, all HER160xG devices - including HER1602G - share identical TO-220AB package dimensions, lead frame geometry, and pinout (Anode 1 / Common Cathode / Anode 2). Voltage ratings differ only in internal die design; PCB layout and mounting are fully interchangeable across the family, simplifying BOM consolidation for multi-voltage designs.
Does HER1602G meet automotive qualification standards?
Yes, HER1602G is explicitly AEC-Q101 qualified, as confirmed in the "FEATURES" section and ordering code notes (HER1602GH denotes AEC-Q101 version). This qualification covers stress tests including temperature cycling, humidity bias, and mechanical shock - validating suitability for automotive powertrain and body electronics applications per industry requirements.
What is the typical forward voltage drop of HER1602G at rated current?
The HER1602G exhibits a typical forward voltage (VF) of 1.0 V at 8 A and 25°C, per electrical specifications table. At full 16 A average current, VF rises to approximately 1.15 V (extrapolated from curve data), maintaining low conduction loss essential for high-efficiency 12–48 V power conversion stages.
How does the dual-die structure of HER1602G impact thermal performance?
The dual-die configuration in HER1602G distributes heat across two silicon junctions within one TO-220AB package, reducing localized hot spots and enabling more uniform thermal transfer to the heatsink. With a combined RθJC of 1.5 °C/W, this architecture sustains 16 A total current while limiting junction-to-case temperature rise to 24°C - critical for reliability in sealed or fanless enclosures.
