Product details
Overview
SMB10J8.0AHE3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection with 1000 W peak pulse power (10/1000 µs), 8.0 V stand-off voltage, and 13.6 V clamping voltage at 73.5 A peak pulse current. It is AEC-Q101 qualified and used to protect automotive sensor signal lines, MOSFET gates, and IC power rails against inductive switching transients.
For engineers reviewing the SMB10J8.0AHE3/5B datasheet, SMB10J8.0AHE3/5B pinout, SMB10J8.0AHE3/5B application, or SMB10J8.0AHE3/5B equivalent, key selection criteria include clamping voltage margin relative to protected device VDS/VCC, IPPM derating above 25 °C, AEC-Q101 qualification status, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode employs a glass-passivated silicon junction optimized for fast response (<1 ns) and low incremental surge resistance, enabling effective suppression of ESD (IEC 61000-4-2) and lightning-induced surges (IEC 61000-4-5). Its unidirectional polarity provides forward conduction path during overvoltage events while maintaining low leakage (<1.0 µA at 8.0 V).
The SMB10J8.0AHE3/5B operates across -55 °C to +150 °C junction temperature range and features MSL Level 1 moisture sensitivity with 260 °C reflow peak, supporting robust automotive-grade assembly. Thermal resistance is 72 °C/W (junction-to-ambient) on standard 5.0 mm × 5.0 mm pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.0 V - maximum reverse working voltage before clamping begins; sets upper limit for normal circuit operation |
| VBR (min/max) | 8.89 V / 9.83 V at 1.0 mA - breakdown threshold range defining turn-on consistency |
| VC @ IPPM | 13.6 V at 73.5 A - clamped voltage during 1000 W surge; determines stress on downstream components |
| PPPM | 1000 W (10/1000 µs waveform) - peak surge energy handling capacity under standardized test condition |
| IFSM | 100 A (8.3 ms half-sine) - non-repetitive forward surge rating for inrush or fault-current scenarios |
| TJ max | +150 °C - maximum junction temperature enabling use in under-hood automotive environments |
| Leakage @ VWM | ≤1.0 µA - minimal standby power loss and signal integrity impact in high-impedance circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0A-E3/5B | Same SMB package and VWM/VC, but commercial-grade (non-AEC-Q101); 1000 W rating unchanged | Lacks automotive qualification; suitable for industrial/commercial designs without AEC requirements | Select when AEC-Q101 is not mandated and cost optimization is prioritized |
| SMAJ8.0AHE3/5B | Lower 400 W PPPM; same VWM/VC but reduced IPPM (35.7 A); SMA (DO-214AC) package with smaller footprint | Insufficient for ISO 7637-2 Pulse 5a (load dump); limited to lower-energy ESD/lightning scenarios | Choose only if board space is constrained and surge threat level is ≤400 W |

The SMB10J8.0AHE3/5B has a maximum clamping voltage (VC) of 13.6 V at its peak pulse current (IPPM) of 73.5 A, measured under the standard 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during a full-rated surge event and is confirmed in Vishay's Document Number 88422, page 2, unidirectional electrical characteristics table.
Is SMB10J8.0AHE3/5B suitable for automotive applications?
Yes, SMB10J8.0AHE3/5B is AEC-Q101 qualified and explicitly designated for automotive use, as indicated by the "HE3" suffix in its ordering code. It meets requirements for under-hood and cabin electronics, including protection of CAN transceivers, sensor signal paths, and power rails subjected to ISO 7637-2 and ISO 16750-2 stress conditions.
What does the "5B" in SMB10J8.0AHE3/5B signify?
The "5B" denotes the preferred package code specifying 13-inch diameter plastic tape and reel packaging containing 3200 units per reel. This format supports high-volume automated SMT placement and is documented in the Ordering Information section of Vishay's SMB10(8)J5.0(C)A datasheet (Document Number 88422, page 3).
How does SMB10J8.0AHE3/5B differ from SMBJ8.0A-E3/5B?
SMB10J8.0AHE3/5B and SMBJ8.0A-E3/5B share identical electrical parameters (VWM, VC, PPPM) and SMB package, but SMB10J8.0AHE3/5B carries AEC-Q101 qualification and RoHS compliance with halogen-free option (HE3), whereas SMBJ8.0A-E3/5B is commercial-grade only (E3 suffix) and lacks automotive qualification.
What is the maximum operating junction temperature for SMB10J8.0AHE3/5B?
The SMB10J8.0AHE3/5B has a maximum operating junction temperature (TJ) of +150 °C, enabling reliable operation in high-temperature environments such as automotive engine compartments or industrial motor control enclosures.
