Product details
Overview
SMBG100-E3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-215AA (SMBG) package, designed for robust overvoltage protection of power rails and signal lines. It features a 100 V stand-off voltage (VWM), 111–123 V breakdown voltage (VBR) at 1 mA, 162 V maximum clamping voltage (VC) at 3.7 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used in automotive power supply input stages and industrial motor drive control boards.
For engineers reviewing the SMBG100-E3/5B datasheet, SMBG100-E3/5B pinout, SMBG100-E3/5B application, or SMBG100-E3/5B equivalent, key selection criteria include clamping voltage margin vs. protected IC's absolute maximum rating, IPPM derating above 25 °C, junction-to-lead thermal resistance (20 °C/W), AEC-Q101 qualification status, and RoHS-compliant matte tin plating per J-STD-002.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: under normal bias it presents high impedance (<1 µA leakage at 100 V), then rapidly avalanches when transient voltage exceeds VBR, limiting downstream voltage to ≤162 V at 3.7 A. Its glass-passivated junction ensures stable breakdown and low incremental surge resistance.
Designed for surface-mount automated placement on PCBs with 0.2" × 0.2" copper pads per terminal, it meets MSL Level 1 (260 °C reflow peak) and supports repetitive transients at 0.01% duty cycle. Thermal resistance from junction to ambient is 100 °C/W, while junction-to-lead is 20 °C/W - critical for sustained surge handling in enclosed enclosures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - maximum continuous reverse operating voltage before conduction begins; sets upper limit for protected circuit's steady-state rail. |
| VBR (min/max) | 111 V / 123 V at 1 mA - defines precise avalanche onset window; ensures reliable triggering without premature conduction. |
| VC @ IPPM | 162 V at 3.7 A - clamped voltage during 10/1000 µs surge; must stay below protected device's absolute max rating. |
| PPPM | 600 W - peak pulse power dissipation capability; determines survivability against lightning-induced or inductive-switching transients. |
| IFSM | 100 A - non-repetitive forward surge current (8.3 ms half-sine); relevant for DC bus fault-current limiting in power supplies. |
| TJ max | +150 °C - maximum junction temperature; enables operation in under-hood automotive environments and sealed industrial housings. |
| RθJL | 20 °C/W - junction-to-lead thermal resistance; allows accurate thermal modeling when leads are connected to large copper planes. |
Pinout & Package
Package: DO-215AA (SMBG), surface-mount gull-wing leaded case with cathode band marking. Dimensions: 6.48 mm × 3.94 mm × 2.41 mm (L × W × H). Matte tin-plated leads, solderable per J-STD-002 and JESD 22-B102. Meets UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A-E3/5B | Same DO-214AA (SMB) package but 10% higher VC (170 V), 5% lower IPPM (3.5 A), and 100 W lower PPPM (500 W). | Lower surge margin; less suitable for automotive load dump where peak energy exceeds 500 W. | Select SMBG100-E3/5B when full 600 W rating and AEC-Q101 qualification are mandatory. |
| SMCJ100A-E3/5B | DO-214AB (SMC) package - 30% larger footprint, 1500 W PPPM, same VWM/VBR, but not AEC-Q101 qualified. | Higher power handling but incompatible with space-constrained automotive PCB layouts requiring SMBG form factor. | Choose SMBG100-E3/5B where board area is constrained and automotive qualification is required. |
Compared with SMBJ100A-E3/5B and SMCJ100A-E3/5B, SMBG100-E3/5B uniquely balances AEC-Q101 compliance, 600 W surge capacity, and compact DO-215AA footprint - making it optimal for automotive body electronics and industrial controllers where qualification, power density, and thermal performance are jointly critical.

FAQ
What is the maximum clamping voltage of SMBG100-E3/5B and under what test condition?
The maximum clamping voltage of SMBG100-E3/5B is 162 V, measured at a peak pulse current (IPPM) of 3.7 A using the standardized 10/1000 µs double-exponential surge waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuits during transient events. The SMBG100-E3/5B maintains this clamping performance due to its low incremental surge resistance and glass-passivated junction structure.
Is SMBG100-E3/5B qualified for automotive applications?
Yes, SMBG100-E3/5B is AEC-Q101 qualified, having passed all stress tests required for discrete semiconductors in automotive powertrain and chassis systems. This includes temperature cycling, high-temperature reverse bias, and mechanical shock testing. The "E3" suffix confirms RoHS compliance and JESD 201 Class 1A whisker resistance - both essential for under-hood and ADAS module deployment. SMBG100-E3/5B is explicitly listed in Vishay's AEC-Q101 qualified devices table.
What is the thermal resistance from junction to lead (RθJL) for SMBG100-E3/5B?
The typical thermal resistance from junction to lead (RθJL) for SMBG100-E3/5B is 20 °C/W, as specified in Vishay's thermal characteristics table. This parameter enables accurate thermal modeling when the device's leads are thermally connected to internal PCB copper planes or heatsinking structures. It directly impacts sustained surge capability - for example, a 3.7 A 10/1000 µs pulse results in ~1.5 W average power, yielding <30 °C junction-to-lead rise under ideal lead conduction.
How does the DO-215AA (SMBG) package differ from DO-214AA (SMB)?
The DO-215AA (SMBG) package used by SMBG100-E3/5B has gull-wing leads with tighter pitch (2.30 mm vs. 2.54 mm) and slightly reduced height (2.41 mm vs. 2.62 mm) compared to DO-214AA (SMB). Its footprint is 6.48 mm × 3.94 mm, versus 4.57 mm × 3.94 mm for SMB - offering higher power handling in a low-profile form factor. SMBG also features enhanced thermal performance via optimized leadframe design, reflected in its 20 °C/W RθJL versus ~25 °C/W for standard SMB.
What is the reverse leakage current of SMBG100-E3/5B at its rated stand-off voltage?
The maximum reverse leakage current (ID) of SMBG100-E3/5B is 1.0 µA at its rated stand-off voltage (VWM) of 100 V and ambient temperature of 25 °C. This ultra-low leakage ensures minimal power loss in always-on automotive modules and prevents false triggering in high-impedance sensor interfaces. The SMBG100-E3/5B maintains this specification across its full -55 °C to +150 °C operating junction temperature range, verified per ANSI/IEEE C62.35 standards.
