Product details
Overview
HER606GH from Taiwan Semiconductor is a high-efficiency, AEC-Q101 qualified glass-passivated silicon rectifier diode in R-6 package, rated for 6 A average forward current, 600 V repetitive peak reverse voltage, and 150 A surge capability; used in automotive-grade DC-DC converters and switching inverters.
For engineers reviewing the HER606GH datasheet, HER606GH pinout, HER606GH application, or HER606GH equivalent, key selection criteria include its 1.7 V forward voltage at 6 A/25°C, 75 ns reverse recovery time, 65 pF junction capacitance, AEC-Q101 qualification, and R-6 package thermal resistance of 37 °C/W.
Technical Context
This device is a single-die, unidirectional, planar-junction rectifier optimized for high-frequency switching applications. Its glass passivation ensures stable junction performance under thermal cycling and humidity stress, while the pure tin-plated leads meet J-STD-002 solderability and JESD201 Class 2 whisker resistance requirements.
The HER606GH operates with a maximum junction temperature of 150°C and exhibits low power loss due to its low VF and high surge robustness. Its reverse recovery time (75 ns) and junction capacitance (65 pF) are specified at 1 MHz and 4.0 V reverse bias, confirming suitability for medium-speed SMPS freewheeling and output rectification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports input rectification in 400 VAC mains-derived systems and high-voltage DC bus applications |
| IF(AV) | 6 A - delivers continuous output current in compact 30–60 W DC-DC converters without forced cooling |
| VF @ 6 A, 25°C | 1.7 V - results in ~10.2 W conduction loss at full load, requiring thermal management per RθJA = 37 °C/W |
| IFSM (8.3 ms) | 150 A - withstands inrush and transient overloads typical in automotive cold-crank and motor drive circuits |
| trr | 75 ns - enables operation up to ~2 MHz switching frequency before reverse recovery losses dominate efficiency |
| CJ @ 1 MHz, 4 V | 65 pF - minimizes capacitive coupling noise and EMI in high dv/dt gate-drive or snubber circuits |
| TJ max | 150 °C - allows operation in under-hood automotive environments with derating above 75 °C ambient |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH6L06S | 6 A / 600 V, TO-220AC package, VF = 1.75 V @ 6 A, trr = 60 ns, not AEC-Q101 qualified | Larger footprint, higher thermal resistance (RθJA ≈ 50 °C/W), suited for non-automotive industrial use | Select when board space permits TO-220 mounting and AEC-Q101 is not required |
| ON Semi MUR660CT | 6 A / 600 V, TO-220AB dual common-cathode, VF = 1.85 V @ 6 A, trr = 50 ns, not AEC-Q101 qualified | Dual-diode configuration enables center-tapped transformer designs; lacks automotive qualification | Choose for dual-output or push-pull topologies where layout supports dual-anode routing |
Compared with STTH6L06S and MUR660CT, the HER606GH offers AEC-Q101 qualification and R-6 axial form factor for through-hole reliability in vibration-prone environments, while trading slightly higher trr for lower cost and smaller PCB footprint-ideal for space-constrained automotive and industrial rectification.

FAQ
What is the maximum junction temperature rating for HER606GH?
The HER606GH has a maximum junction temperature (TJ max) of +150°C, validated per AEC-Q101 stress testing. This allows operation in under-hood automotive environments and high-ambient industrial settings when derated per the forward current derating curve. The HER606GH must be mounted with adequate copper area or heatsinking to maintain TJ ≤ 150°C under full 6 A load.
Is HER606GH pin-compatible with other HER60xG variants?
Yes, all HER601G–HER606G devices share identical R-6 package dimensions, lead spacing, polarity marking (cathode band), and mechanical outline. The HER606GH is mechanically interchangeable with HER601G–HER605G, but electrical parameters-including VRRM, VF, and trr-differ per voltage grade and must be verified for circuit compatibility.
Does HER606GH require a heatsink in 6 A continuous operation?
At 6 A and 25°C ambient, the HER606GH dissipates ~10.2 W (VF × IF). With RθJA = 37 °C/W, junction temperature rises ~377°C above ambient-exceeding 150°C. Therefore, a heatsink or substantial PCB copper pour is mandatory. Derating to ~3.5 A is recommended for no-heatsink operation at 25°C ambient.
What does the 'H' suffix in HER606GH signify?
The 'H' suffix in HER606GH indicates full AEC-Q101 qualification per Rev D, including stress tests for temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing. This distinguishes it from the non-H variant (HER606G), which lacks automotive qualification documentation and test reports.
How does HER606GH's reverse recovery time affect EMI in switching circuits?
The HER606GH's 75 ns trr generates measurable reverse recovery current spikes during turn-off, increasing high-frequency EMI in the 10–100 MHz range. Layout best practices-such as minimizing loop area, using local RC snubbers, and placing the HER606GH close to the switching node-are essential to contain radiated emissions in sensitive automotive and industrial systems.
