Product details

Overview

S2G-E3/5BT from Vishay General Semiconductor is a surface-mount glass passivated silicon rectifier diode rated for 400 V repetitive peak reverse voltage, 1.5 A average forward current, and 50 A non-repetitive surge current; it features 1.15 V forward voltage at 1.5 A, 1.0 μA reverse leakage at 25 °C, and 2.0 μs typical reverse recovery time - used in automotive DC-DC converters and industrial power supply freewheeling paths.

For engineers reviewing the S2G-E3/5BT datasheet, S2G-E3/5BT pinout, S2G-E3/5BT application, or S2G-E3/5BT equivalent, key selection criteria include its DO-214AA (SMB) package, AEC-Q101 qualification (via HE3 variant), MSL Level 1 rating, 150 °C max junction temperature, and low-profile suitability for automated placement in space-constrained power stages.

Technical Context

This device operates as a single-die, unidirectional silicon PN junction rectifier with glass-passivated chip construction ensuring stable performance under thermal cycling and humidity exposure. Its 2.0 μs reverse recovery time and 16 pF junction capacitance at 4.0 V/1 MHz support moderate-frequency switching in flyback and boost topologies.

The S2G-E3/5BT shares identical thermal resistance values (R_θJA = 53 °C/W, R_θJL = 16 °C/W) and mechanical outline (DO-214AA/SMB) across the S2x family, enabling direct layout reuse when substituting between voltage grades - provided derating curves for forward current vs. lead temperature are observed.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - maximum repetitive reverse blocking capability without breakdown
I_F(AV)	1.5 A at T_L = 100 °C - continuous DC output current limit in PCB-mounted configuration
I_FSM	50 A - peak surge current tolerance for 8.3 ms half-sine waveform, critical for inrush handling
V_F	1.15 V at I_F = 1.5 A - forward conduction loss directly impacts efficiency in low-voltage power rails
I_R	1.0 μA at 25 °C - minimal leakage ensures low standby power in battery-backed systems

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1L06S	600 V V_RRM, 1.0 A I_F(AV), TO-277 package, 1.7 V V_F	Higher voltage rating but lower current and higher forward drop	Select when 600 V blocking is required and thermal budget permits higher V_F loss

Compared with STTH1L06S and MUR160, the S2G-E3/5BT delivers higher average current (1.5 A vs. 1.0 A), lower forward voltage (1.15 V vs. 1.7 V), and surface-mount DO-214AA packaging - making it preferable for modern automotive and industrial power supplies requiring AEC-Q101 alignment and automated assembly.

FAQ

What is the maximum junction temperature rating for the S2G-E3/5BT?

The S2G-E3/5BT has a maximum junction temperature (T_J) of 150 °C, verified per Vishay Document Number 88712. This rating allows reliable operation in under-hood automotive environments and industrial enclosures when thermal design adheres to the specified R_θJA = 53 °C/W and R_θJL = 16 °C/W values. The S2G-E3/5BT must be mounted on PCB copper pads per recommended layout to achieve this rating.

Is the S2G-E3/5BT AEC-Q101 qualified?

The S2G-E3/5BT is RoHS-compliant and commercial-grade; AEC-Q101 qualification applies only to variants with the HE3 suffix (e.g., S2GHE3/5BT). The S2G-E3/5BT itself is not AEC-Q101 qualified, though it shares identical electrical and thermal characteristics with the HE3 version. For automotive applications requiring formal qualification, specify S2GHE3/5BT instead of S2G-E3/5BT.

What does the "5BT" in S2G-E3/5BT indicate?

The "5BT" in S2G-E3/5BT denotes the packaging configuration: 13-inch diameter plastic tape and reel, with a base quantity of 3200 units per reel. This differs from "52T", which specifies 7-inch tape-and-reel with 750 units. Both use the same DO-214AA (SMB) package and share identical electrical specifications. The S2G-E3/5BT is optimized for high-volume SMT line feeding.

What is the reverse recovery time (t_rr) of the S2G-E3/5BT and how is it measured?

The S2G-E3/5BT has a typical reverse recovery time (t_rr) of 2.0 μs, measured under conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A, per Vishay Document Number 88712. This value reflects the time required for minority carriers to clear after forward conduction ceases, directly influencing switching loss in 100–300 kHz power converters. The S2G-E3/5BT is not an ultrafast or soft-recovery diode but suits general-purpose rectification.

Can the S2G-E3/5BT replace the S2J-E3/5BT in a design?

No - the S2G-E3/5BT (400 V V_RRM) and S2J-E3/5BT (600 V V_RRM) are distinct voltage-grade variants within the same S2x family. Substituting S2G-E3/5BT for S2J-E3/5BT risks reverse breakdown under 600 V transient conditions. Derating analysis must confirm that system-level peak reverse voltage remains ≤400 V before using S2G-E3/5BT. The S2G-E3/5BT is not a drop-in replacement for higher-voltage S2x parts.
