Product details
Overview
S4GH from Taiwan Semiconductor is a 4A, 600V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring glass-passivated junction, 100A peak surge current capability, 1.15V max forward voltage at 4A/25°C, and AEC-Q101 qualification for automotive use.
For engineers reviewing the S4GH datasheet, S4GH pinout, S4GH application, or S4GH equivalent, key selection considerations include repetitive peak reverse voltage (600V), thermal resistance (13°C/W junction-to-lead), reverse recovery time (1500ns), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance.
Technical Context
The S4GH is a single-die, standard recovery rectifier optimized for DC-DC conversion and snubber circuits where moderate switching speed and high surge robustness are prioritized over ultrafast recovery. Its 1500ns trr and 60pF junction capacitance reflect trade-offs favoring ruggedness and low conduction loss over high-frequency operation.
Designed for surface-mount assembly with matte tin-plated leads compliant to J-STD-002, the device operates across -55°C to +150°C junction temperature range and meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements for its molding compound.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive reverse blocking voltage; defines maximum DC or peak AC voltage the diode can withstand in reverse bias without breakdown. |
| IF | 4 A - Continuous average forward current rating at case temperature ≤ 75°C; determines steady-state power handling in rectification paths. |
| IFSM | 100 A - Non-repetitive peak surge current (8.3ms half-sine); supports inrush and transient overload tolerance in automotive and industrial power supplies. |
| VF | ≤1.15 V @ 4A, 25°C - Forward voltage drop at rated current; directly impacts conduction losses and thermal design in high-current rectifiers. |
| trr | 1500 ns - Reverse recovery time under IF=0.5A, IR=1.0A, Irr=0.25A; limits usable frequency range and influences snubber sizing in flyback or clamp circuits. |
| RθJL | 13 °C/W - Junction-to-lead thermal resistance; enables accurate thermal modeling when mounted on PCB copper pads with direct lead heat sinking. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH4R06S | 600V VRRM, 4A IF, but faster trr (75ns) and higher VF (1.7V typ); TO-220AC package. | Preferred in high-frequency PFC or ZVS circuits where fast recovery reduces switching loss-but requires heatsink and through-hole assembly. | Select STTH4R06S only if trr < 200ns is required and board space allows TO-220 mounting. |
| SB460-E3/54 | 60V VRRM (not 600V), 4A IF, Schottky architecture; DO-214AA (SMB) package; VF ≈ 0.65V. | Suitable only for low-voltage (<100V) DC-DC outputs; cannot replace S4GH in 600V-blocking roles like snubbers or AC front-ends. | Use SB460-E3/54 only in sub-100V applications where ultra-low VF outweighs voltage limitation. |
Compared with STTH4R06S and SB460-E3/54, the S4GH uniquely balances 600V blocking, 4A current, AEC-Q101 compliance, and SMC surface-mount compatibility-making it the only drop-in solution for automotive 600V rectification where surge robustness and manufacturability are jointly critical.

FAQ
What is the maximum junction temperature rating for the S4GH?
The S4GH has a maximum junction temperature (TJ) rating of +150°C, with operational range from -55°C to +150°C. This rating enables reliable operation in under-hood automotive environments and high-ambient industrial settings. Derating curves in the datasheet define allowable forward current versus case temperature, and thermal design must account for RθJL = 13°C/W to maintain S4GH junction temperature within limit under full 4A load.
Is the S4GH pin-compatible with other devices in the S4xH series?
Yes, all S4xH devices-including S4AH, S4BH, S4DH, S4GH, S4JH, S4KH, and S4MH-share identical DO-214AB (SMC) package dimensions, pinout, and thermal characteristics. Only the VRRM rating differs (50V to 1000V), so S4GH can be substituted for other S4xH variants on the same PCB footprint when 600V blocking is required, provided electrical stresses remain within S4GH's absolute maximum ratings.
Does the S4GH meet automotive reliability standards?
Yes, the S4GH is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and electrostatic discharge per JESD22-A114. This qualification confirms suitability for automotive power electronics such as LED drivers, body control modules, and engine management subsystems-where field failure is unacceptable and long-term parametric stability is mandatory for S4GH deployment.
What is the reverse recovery time (trr) specification for the S4GH?
The S4GH has a typical reverse recovery time (trr) of 1500 ns, measured under conditions of IF = 0.5A, IR = 1.0A, and Irr = 0.25A. This value reflects its standard recovery behavior and informs snubber design and switching loss estimation in topologies like flyback or forward converters. Designers should verify that system operating frequency and associated di/dt do not cause excessive switching losses or voltage overshoot due to S4GH's trr characteristic.
How is polarity marked on the S4GH package?
The S4GH uses a molded cathode band on the body to indicate the cathode terminal-consistent with industry-standard DO-214AB (SMC) marking convention. The cathode corresponds to Lead 2 (right-hand lead when viewing the marking side with cathode band at left), and the anode is Lead 1. This marking ensures unambiguous orientation during automated pick-and-place and manual inspection, preventing reverse-bias installation errors that could cause immediate failure of the S4GH in circuit.
