Product details

Overview

S5GHE3_A/H from Vishay General Semiconductor is a surface-mount glass passivated rectifier diode rated for 400 V repetitive peak reverse voltage, 5.0 A average forward current, and 100 A non-repetitive surge current, with 1.15 V forward voltage drop at 5.0 A - used in automotive-grade DC/DC converter freewheeling paths and industrial power supply output rectification.

For engineers reviewing the S5GHE3_A/H datasheet, S5GHE3_A/H pinout, S5GHE3_A/H application, or S5GHE3_A/H equivalent, key selection criteria include AEC-Q101 qualification, DO-214AB (SMC) package thermal performance, low leakage (10 µA @ 25 °C), and 2.5 µs reverse recovery time in high-frequency switching environments.

Technical Context

This device is a single-junction, unidirectional silicon rectifier optimized for general-purpose and automotive power conversion. It features a glass-passivated chip junction enabling stable operation up to 175 °C junction temperature and compliance with J-STD-020 MSL Level 1 reflow profiles.

The S5GHE3_A/H implements a planar epitaxial structure with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102, and meets JESD 201 Class 2 whisker resistance. Its 40 pF junction capacitance at 4.0 V / 1 MHz supports moderate-speed switching in offline and DC/DC applications.

Equivalent & Alternatives

The following parts are listed as comparable options for similar rectifier diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH5L06S	600 V V_RRM, 5 A I_F(AV), 1.85 V V_F, TO-277 package	Higher voltage rating but higher forward drop; not AEC-Q101 qualified	Preferred where 600 V blocking is mandatory and automotive qualification is not required

FAQ

What is the peak repetitive reverse voltage rating of the S5GHE3_A/H?

The S5GHE3_A/H has a maximum repetitive peak reverse voltage (V_RRM) of 400 V, verified per Vishay Document Number 88931. This rating ensures reliable blocking capability in 280 V RMS AC input stages and 400 V DC bus applications. The S5GHE3_A/H maintains this rating across its full operating temperature range of –55 °C to +175 °C, with derating applied only above T_L = 100 °C per the forward current derating curve.

Is the S5GHE3_A/H qualified for automotive applications?

Yes, the S5GHE3_A/H is AEC-Q101 qualified, as explicitly stated in the Vishay datasheet (Document Number 88931, Revision 21-May-2024). The "HE3" suffix denotes RoHS-compliant and AEC-Q101 qualified construction. This qualification covers stress tests including HTGB, HTRB, TCT, and UHAST, confirming suitability for under-hood and chassis-mounted automotive power electronics where reliability at elevated temperatures is essential.

What package type does the S5GHE3_A/H use, and what are its mounting requirements?

The S5GHE3_A/H uses the SMC (DO-214AB) surface-mount package, with mechanical dimensions documented in Vishay's 88931 datasheet. Mounting requires a 0.3" × 0.3" (8.0 mm × 8.0 mm) copper pad area for optimal thermal performance, achieving a typical junction-to-lead thermal resistance (R_θJL) of 10 °C/W. The device is MSL Level 1 and supports peak reflow temperatures up to 260 °C per J-STD-020.

What is the forward voltage drop of the S5GHE3_A/H at rated current?

The S5GHE3_A/H exhibits a maximum instantaneous forward voltage (V_F) of 1.15 V at 5.0 A and 25 °C, per electrical characteristics table in Vishay Document Number 88931. This value increases slightly with temperature but remains below 1.3 V at 125 °C, contributing to high efficiency in 12–48 V power conversion stages where conduction loss directly impacts thermal design and system efficiency.

Does the S5GHE3_A/H have a specified reverse recovery time?

Yes, the S5GHE3_A/H has a typical reverse recovery time (t_rr) of 2.5 µs, measured at I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This parameter is confirmed in the Electrical Characteristics section of Vishay's 88931 datasheet. The 2.5 µs t_rr supports operation in switching power supplies up to approximately 200 kHz while maintaining manageable turn-off losses and EMI generation.
