Product details
Overview
SMB10J8.0HE3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, designed for high-energy surge protection on power and signal lines. It features 8.0 V stand-off voltage (VWM), 13.6 V maximum clamping voltage (VC) at 50 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 μs waveform. It is AEC-Q101 qualified and used to protect MOSFETs and ICs against inductive switching transients in automotive power supplies.
For engineers reviewing the SMB10J8.0HE3/5B datasheet, SMB10J8.0HE3/5B pinout, SMB10J8.0HE3/5B application, or SMB10J8.0HE3/5B equivalent, key selection criteria include clamping performance under 50 A surge, unidirectional polarity with cathode band marking, RoHS-compliant AEC-Q101 qualification, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds 8.0 V (VWM), it avalanches near its 8.89–9.83 V breakdown range (VBR at 1.0 mA), limiting transient energy by diverting surge current to ground. Its low incremental surge resistance ensures stable clamping up to 13.6 V at rated IPPM.
Thermally, it sustains operation from –55 °C to +150 °C junction temperature, with typical junction-to-ambient thermal resistance of 72 °C/W and junction-to-lead of 20 °C/W. The glass-passivated chip junction and matte tin-plated leads meet J-STD-002 solderability and JESD 201 Class 2 whisker resistance requirements.
Key Specifications

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 DO-214AA package and 8.0 V VWM, but rated for 600 W PPPM (vs. 1000 W); lower IPPM (30 A vs. 50 A). | Not suitable for >600 W surge environments like automotive load dump; acceptable for consumer-grade ESD-only protection. | Select SMB10J8.0HE3/5B when full 1000 W IEC 61000-4-5 compliance is required; choose SMBJ8.0A-E3/5B only for cost-sensitive non-automotive designs. |
| 1.5SMC8.0A | DO-214AB (SMC) package (larger footprint), same 8.0 V VWM, 1000 W PPPM, but higher thermal resistance (RθJA = 11 °C/W vs. 72 °C/W). | Requires larger PCB area and offers inferior thermal dissipation in confined enclosures; not AEC-Q101 qualified. | Prefer SMB10J8.0HE3/5B for space-constrained automotive modules; use 1.5SMC8.0A only if legacy board layout mandates SMC footprint. |

The SMB10J8.0HE3/5B has a maximum clamping voltage (VC) of 13.6 V when subjected to its rated 50 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured under standardized test conditions per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMB10J8.0HE3/5B maintains this clamping performance consistently due to its glass-passivated junction and low incremental surge resistance.
Is SMB10J8.0HE3/5B suitable for automotive applications?
Yes, SMB10J8.0HE3/5B is AEC-Q101 qualified and specifically designed for automotive use, including powertrain control units, body electronics, and infotainment systems. Its qualification covers temperature cycling, highly accelerated life testing (HALT), and ESD robustness per automotive reliability standards. The HE3 suffix denotes AEC-Q101 compliance, and the device operates reliably from –55 °C to +150 °C junction temperature-meeting stringent OEM environmental requirements.
What does the "HE3/5B" suffix mean in SMB10J8.0HE3/5B?
The "HE3" suffix indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "5B" specifies packaging in 13-inch diameter plastic tape and reel with 3200 units per reel. This format supports high-speed automated pick-and-place assembly and ensures traceable, moisture-safe handling per MSL Level 1 (260 °C peak reflow). The SMB10J8.0HE3/5B is distinct from commercial-grade E3 variants lacking automotive qualification.
How does SMB10J8.0HE3/5B differ from SMBJ8.0A-E3/5B?
SMB10J8.0HE3/5B delivers 1000 W peak pulse power (PPPM) versus 600 W for SMBJ8.0A-E3/5B, supporting higher-energy transients such as automotive load dump. It also achieves 50 A IPPM (vs. 30 A) and carries AEC-Q101 qualification (HE3 vs. E3). Both share the DO-214AA package and 8.0 V VWM, but SMB10J8.0HE3/5B is engineered for mission-critical automotive and industrial surge protection where sustained 1000 W capability is mandatory.
