Product details

Overview

SMBG10A-E3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 10 V stand-off voltage (V_WM), 11.1–12.3 V breakdown voltage (V_BR) at 1 mA, 17.0 V clamping voltage (V_C) at 35.3 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O protection circuits.

For engineers reviewing the SMBG10A-E3/5B datasheet, SMBG10A-E3/5B pinout, SMBG10A-E3/5B application, or SMBG10A-E3/5B equivalent, key selection criteria include unidirectional polarity, DO-215AA (SMBG) package compatibility, AEC-Q101 qualification, 150 °C maximum junction temperature, and low 5.0 µA reverse leakage at V_WM.

Technical Context

This TVS diode operates as a shunt-clamping device that remains high-impedance below V_WM = 10 V and rapidly transitions to low-impedance conduction above V_BR = 11.1–12.3 V to divert surge energy. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while the low incremental surge resistance supports effective clamping under repetitive transients.

The SMBG10A-E3/5B is rated for 100 A non-repetitive forward surge current (I_FSM, 8.3 ms half-sine), has a thermal resistance of 100 °C/W (junction-to-ambient), and meets J-STD-020 MSL Level 1 with 260 °C reflow peak - confirming suitability for automated SMT assembly in high-reliability environments.

Key Specifications

Parameter	Value and Actual Design Meaning
V_WM	10 V - Maximum continuous reverse operating voltage before clamping begins
V_BR @ I_T = 1 mA	11.1–12.3 V - Guaranteed breakdown threshold defining turn-on precision
V_C @ I_PPM = 35.3 A	17.0 V - Clamped voltage during 600 W surge, limiting stress on downstream ICs
I_D @ V_WM	5.0 µA - Low leakage preserves signal integrity and minimizes standby power loss
P_PPM	600 W - Peak surge power handling capability with standard 10/1000 µs waveform

Equivalent & Alternatives

The following parts are listed as comparable options for similar transient voltage suppression applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SMBJ10A-E3/52	Same V_WM/V_C, but SMB (DO-214AA) package; 100 W lower P_PPM (500 W)	Limited to lower-energy transients; not AEC-Q101 qualified	Select when cost sensitivity outweighs automotive qualification or 600 W margin
1.5SMC10A	Same electrical specs, but larger SMC (DO-214AB) package; higher thermal mass but 2× PCB area	Better thermal dissipation for high-duty-cycle surges; less suitable for dense layouts	Choose when board layout allows larger footprint and enhanced surge endurance is prioritized

Compared with SMBJ10A-E3/52 and 1.5SMC10A, the SMBG10A-E3/5B delivers AEC-Q101 compliance and 600 W clamping in the smallest qualified footprint (DO-215AA), making it optimal for space-constrained automotive and industrial modules where reliability and size are co-prioritized.

FAQ

What is the clamping voltage of SMBG10A-E3/5B at its rated peak pulse current?

The SMBG10A-E3/5B has a maximum clamping voltage (V_C) of 17.0 V at 35.3 A peak pulse current (I_PPM) under a 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events and is measured per ANSI/IEEE C62.35 standards. The SMBG10A-E3/5B maintains this clamping performance across its specified operating temperature range.

Is SMBG10A-E3/5B suitable for automotive applications?

Yes, the SMBG10A-E3/5B is AEC-Q101 qualified and explicitly rated for automotive use per Vishay's documentation. Its construction includes glass-passivated junctions, MSL Level 1 moisture sensitivity, and guaranteed operation from –55 °C to +150 °C - meeting critical requirements for engine control units, body electronics, and ADAS sensor modules. The SMBG10A-E3/5B carries the HE3/HE3-compatible qualification suffix lineage.

What does the "E3/5B" suffix indicate in SMBG10A-E3/5B?

The "E3" denotes RoHS-compliant, industrial-grade termination with matte tin plating; "5B" specifies packaging in 13-inch diameter plastic tape and reel with a base quantity of 3200 units. This differs from "52" (7-inch reel, 750 units) and confirms full compliance with JESD 201 Class 2 whisker resistance and J-STD-002 solderability standards. The SMBG10A-E3/5B is not halogen-free - that variant uses the "M3" suffix.

How does SMBG10A-E3/5B differ from bidirectional variants like SMBG10CA?

The SMBG10A-E3/5B is unidirectional, with cathode marked by a band and intended for DC-biased lines where surge polarity is known (e.g., V_CC-to-ground). In contrast, SMBG10CA is bidirectional, symmetric in both directions, and used in AC-coupled or floating signal paths. Electrical parameters (V_WM, V_BR, V_C) are identical, but the SMBG10A-E3/5B cannot replace SMBG10CA in bidirectional applications without circuit redesign.

What is the maximum reverse leakage current for SMBG10A-E3/5B at its stand-off voltage?

The SMBG10A-E3/5B exhibits a maximum reverse leakage current (I_D) of 5.0 µA at its 10 V stand-off voltage (V_WM) and 25 °C ambient temperature. This low leakage ensures minimal impact on high-impedance sensor nodes or battery-powered circuits. Leakage increases with temperature but remains below 50 µA up to 125 °C per Vishay's derating curves - a key design factor for SMBG10A-E3/5B deployment in thermally demanding environments.
