Product details
Overview
HERAF1602GH from Taiwan Semiconductor is a 16A, 100V AEC-Q101-qualified glass-passivated high-efficiency rectifier in ITO-220AC package, featuring 1.0V forward voltage at 16A/25°C, 250A surge capability, and 2°C/W junction-to-case thermal resistance. It serves as a primary output rectifier in automotive DC-DC converters.
For engineers reviewing the HERAF1602GH datasheet, HERAF1602GH pinout, HERAF1602GH application, or HERAF1602GH equivalent, key selection criteria include repetitive peak reverse voltage (100V), forward voltage consistency across temperature, AEC-Q101 qualification status, and thermal performance under high-current switching conditions.
Technical Context
This device is a single-die, standard recovery silicon rectifier optimized for high-current, medium-voltage switching power supplies. Its glass-passivated junction ensures stable reverse leakage (<10 µA at 25°C) and robustness against humidity and contamination.
The ITO-220AC package enables direct heatsink mounting with ≤0.56 N·m torque, supporting continuous 16A conduction while maintaining junction temperature ≤150°C. Thermal resistance of 2°C/W allows predictable derating up to 125°C case temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum non-repetitive reverse blocking voltage; defines safe operating range in flyback/freewheeling topologies |
| IF | 16 A - Continuous average forward current; determines minimum heatsink sizing for steady-state operation |
| IFSM | 250 A - Peak non-repetitive surge current (8.3 ms half-sine); withstands inrush and fault transients without failure |
| VF @ 16A, 25°C | 1.0 V - Forward voltage drop; directly impacts conduction loss (16W at full load) and thermal design |
| RθJC | 2 °C/W - Junction-to-case thermal resistance; enables accurate thermal modeling when mounted to heatsink |
| IR @ 100V, 25°C | 10 µA - Reverse leakage current; critical for low-power standby efficiency and system-level leakage budgets |
| TJ max | 150 °C - Maximum junction temperature; sets upper limit for reliability-aware thermal margining |
Pinout & Package
Package: ITO-220AC - Insulated TO-220 variant with isolated tab, UL 94V-0 molding compound, matte tin-plated leads, and polarity marking per device top-side laser etch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Current entry point during forward conduction | Connected to switching node or transformer secondary; must handle full 16A RMS and 250A surge |
| Cathode (Lead 2) | Current exit point during forward conduction | Typically tied to output capacitor ground or common return; low-inductance layout essential |
| Tab (Isolated) | Thermal interface only - electrically isolated | Mounts directly to heatsink; no electrical connection required; enables 2°C/W RθJC performance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1602D | 16A/100V, TO-220AC, VF = 1.15V @ 16A, RθJC = 2.5°C/W, not AEC-Q101 qualified | Targeted at industrial SMPS; lacks automotive qualification and tighter VF spec | Select when AEC-Q101 is not required and 0.15V higher VF is acceptable for thermal budget |
| VS-16EWH06-M3 | 16A/600V, TO-220AC, VF = 1.7V @ 16A, RθJC = 2.2°C/W, AEC-Q101 qualified | Higher VRRM suited for 400V+ bus systems; 0.7V higher VF increases conduction loss by ~11W | Select only if 600V rating is mandatory; avoid in 100V designs due to unnecessary VF penalty |
Compared with STTH1602D and VS-16EWH06-M3, HERAF1602GH uniquely balances AEC-Q101 compliance, 1.0V VF, and 100V rating-making it optimal for cost-sensitive, thermally constrained automotive DC-DC where both qualification and efficiency are non-negotiable.

FAQ
What is the maximum junction temperature rating for HERAF1602GH?
The HERAF1602GH has a maximum junction temperature (TJ max) of +150°C, verified per AEC-Q101 stress testing. This rating enables operation in under-hood automotive environments and high-ambient industrial settings. Derating curves in the datasheet define safe IF limits above 25°C case temperature. HERAF1602GH must be mounted to an appropriate heatsink to maintain TJ ≤150°C under full 16A load.
Is HERAF1602GH pin-compatible with other devices in the HERAF160xG family?
Yes, all HERAF160xG and HERAF160xGH variants-including HERAF1602GH-share identical ITO-220AC packaging, pinout (anode/cathode/tab), and mechanical footprint. Voltage ratings differ (50V–600V), but board layout, mounting, and thermal interface remain unchanged across the family. HERAF1602GH may be substituted for HERAF1601GH or HERAF1603GH on the same PCB if voltage margin permits.
Does HERAF1602GH require a heatsink in typical applications?
Yes, HERAF1602GH requires a heatsink for continuous 16A operation. With RθJC = 2°C/W and 1.0V VF, conduction loss reaches ~16W at full load. Without heatsinking, junction temperature would exceed 150°C even at modest ambient. The ITO-220AC tab is electrically isolated and designed for direct heatsink attachment using ≤0.56 N·m torque-no insulating washer needed.
What does the 'H' suffix in HERAF1602GH signify?
The 'H' suffix in HERAF1602GH indicates full AEC-Q101 qualification per revision C, including stress tests for temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing. HERAF1602GH is certified for automotive use, whereas HERAF1602G (without 'H') is intended for industrial applications and lacks this qualification. Both share identical electrical specs and packaging.
How does HERAF1602GH perform at elevated junction temperatures?
HERAF1602GH maintains stable performance up to 150°C TJ: VF increases to ~1.15V at 125°C (vs. 1.0V at 25°C), and IR rises to 400 µA at 125°C (vs. 10 µA at 25°C). These shifts are characterized in the datasheet's electrical specs table and curves. Designers must account for VF drift in thermal modeling, but HERAF1602GH remains fully functional and reliable within its rated TJ range.
