Product details
Overview
HERA806GH from Taiwan Semiconductor is an AEC-Q101-qualified, glass-passivated, single-die ultrafast recovery rectifier in TO-220AC package, rated for 8 A average forward current, 600 V repetitive peak reverse voltage, and 150 A non-repetitive surge current - used in automotive DC/DC converters and switching inverters.
For engineers reviewing the HERA806GH datasheet, HERA806GH pinout, HERA806GH application, or HERA806GH equivalent, key selection criteria include its 1.7 V max forward voltage at 8 A/25°C, 80 ns reverse recovery time, 55 pF junction capacitance, 2 °C/W junction-to-case thermal resistance, and AEC-Q101 qualification for under-hood automotive power stages.
Technical Context
This device is a single-die, ultrafast recovery silicon rectifier optimized for high-efficiency switching-mode power supplies. Its 600 V VRRM, 80 ns trr, and low 55 pF CJ enable reduced switching losses in hard-switched topologies operating up to several hundred kHz.
The HERA806GH integrates glass passivation for moisture resistance and reliability, matte tin-plated leads compliant with J-STD-002, and meets JESD201 Class 2 whisker resistance - all supporting automotive-grade deployment in engine control units and on-board chargers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports 400 V DC bus designs with ≥50% safety margin against transients |
| IF | 8 A continuous - delivers stable output in compact 30–100 W DC/DC converters |
| IFSM | 150 A (8.3 ms half-sine) - withstands inrush and fault currents in automotive start-stop systems |
| VF max | 1.7 V @ 8 A, 25°C - reduces conduction loss vs. standard fast rectifiers (e.g., ~0.3 W lower at 8 A) |
| trr | 80 ns - limits reverse recovery charge (Qrr) to minimize EMI and switching loss in 100–500 kHz SMPS |
| RθJC | 2 °C/W - enables direct heatsink mounting for thermal management without forced air in space-constrained modules |
| CJ | 55 pF @ 1 MHz, 4 V - lowers capacitive coupling noise in high-dv/dt gate-drive isolation circuits |
Pinout & Package
Package: TO-220AC - 3-lead, single-ended, isolated tab (cathode-connected tab), matte tin-plated leads, UL 94V-0 molding compound, 1.80 g typical weight, 0.56 N·m max mounting torque.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input terminal for forward conduction path | Connected to switching node (e.g., MOSFET drain) in flyback/freewheeling configurations |
| Cathode | Output terminal for forward conduction path | Connected to output rail; electrically tied to metal tab for low-inductance thermal path |
| Tab (Cathode) | Thermal and electrical cathode connection | Must be electrically isolated from heatsink unless system design requires cathode-referenced thermal interface |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive power electronics per stress test requirements (HTOL, TC, HAST, etc.) |
| Glass-passivated junction | Prevents moisture ingress and metallization corrosion in humid under-hood environments |
| Ultrafast recovery (80 ns) | Reduces switching loss and EMI generation compared to standard recovery rectifiers (>500 ns) |
| Low VF (1.7 V max) | Improves efficiency in high-current, low-voltage secondary-side rectification (e.g., 12 V outputs) |
| RoHS + halogen-free | Complies with IEC 61249-2-21 and automotive ELV directive for sustainable manufacturing |
Applications
| Automotive DC/DC Converters | On-Board Charger (OBC) Auxiliary Supplies |
|---|---|
Use Scenario: Step-down conversion from 400 V battery to 12 V/48 V auxiliary rails in EV power distribution units. IC Role / Device Role / Timing Role: Ultrafast freewheeling diode in synchronous buck or flyback topology, handling 8 A continuous output current.

IC Role / Device Role / Timing Role: High-current, low-VF rectifier in active OR-ing or soft-start circuitry. Use Value: 1.7 V VF max reduces conduction loss during high-current charging phase, lowering thermal stress on PCB traces and connectors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH8R06DJF | 600 V, 8 A, 75 ns trr, 1.85 V VF max, TO-220AC, AEC-Q101 qualified | Slightly higher VF increases conduction loss; identical surge rating and thermal resistance | Preferred where tighter trr tolerance is critical, but requires validation of higher forward drop impact on thermal design |
| VS-8EWH06FN-M3 | 600 V, 8 A, 85 ns trr, 1.65 V VF max, TO-220AC, AEC-Q101 qualified | Lower VF improves efficiency; slightly longer trr may increase EMI in >300 kHz designs | Better for thermally constrained layouts; verify EMI compliance if operating above 250 kHz |
Compared with STTH8R06DJF and VS-8EWH06FN-M3, the HERA806GH offers a balanced trade-off: mid-range trr (80 ns) and moderate VF (1.7 V), making it suitable for cost-sensitive automotive and industrial converters where both efficiency and EMI must be managed without extreme optimization.

FAQ
What is the maximum junction temperature rating for HERA806GH?
The HERA806GH has a maximum junction temperature (TJ) rating of +150°C, verified per AEC-Q101 stress testing. This allows operation in under-hood automotive environments up to +125°C ambient when mounted on a heatsink with ≤2 °C/W total thermal resistance. The HERA806GH maintains specified electrical parameters within this range.
Is HERA806GH pin-compatible with other TO-220AC rectifiers?
Yes - the HERA806GH uses the standard TO-220AC outline with anode, cathode, and cathode-connected tab pinout. It is mechanically and electrically compatible with industry-standard TO-220AC rectifiers such as MUR860 or STTH8R06DJF, provided thermal and electrical design margins accommodate its specific VF and trr values.
Does HERA806GH meet automotive qualification standards?
Yes - the "H" suffix in HERA806GH explicitly denotes AEC-Q101 qualification. This includes full stress testing for high-temperature operating life, temperature cycling, humidity bias, and mechanical shock - confirming suitability for automotive power electronics including engine control modules and onboard chargers.
What is the reverse leakage current specification for HERA806GH at elevated temperature?
At 125°C junction temperature and rated reverse voltage (600 V), the HERA806GH exhibits a maximum reverse leakage current (IR) of 400 µA. At 25°C, the limit is 10 µA. These values are measured under pulsed conditions (30 ms PW) and reflect stable performance across automotive thermal operating ranges.
How does the junction capacitance of HERA806GH affect high-frequency layout?
The HERA806GH has a typical junction capacitance (CJ) of 55 pF at 1 MHz and 4 V reverse bias. This low value minimizes capacitive coupling noise in high-dv/dt gate-drive feedback paths and reduces ringing in snubberless designs - enabling cleaner waveforms and relaxed PCB layout constraints compared to rectifiers with >100 pF CJ.
