Product details
Overview
SMB10J9.0HE3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, designed for high-energy surge protection on DC power rails and signal lines. It features a 9.0 V stand-off voltage (VWM), 15.4 V maximum clamping voltage (VC) at 10 A peak pulse current, and 1000 W peak pulse power rating with 10/1000 µs waveform. It is AEC-Q101 qualified and used to protect automotive sensor interfaces and industrial control inputs against ESD and load dump transients.
For engineers reviewing the SMB10J9.0HE3/5B datasheet, SMB10J9.0HE3/5B pinout, SMB10J9.0HE3/5B application, or SMB10J9.0HE3/5B equivalent, key selection criteria include clamping voltage margin relative to protected IC's absolute maximum rating, unidirectional polarity alignment with DC bias, AEC-Q101 qualification for automotive deployment, and thermal resistance (RθJA = 72 °C/W) under PCB pad constraints.
Technical Context
This TVS operates as a voltage-clamped shunt protector: when reverse-biased voltage exceeds its breakdown threshold (10.0–11.1 V at 1 mA), it avalanches to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable leakage (<1.0 µA at 9.0 V) and fast response (<1 ns), critical for suppressing ESD events per IEC 61000-4-2.
The device is rated for 100 A non-repetitive forward surge (8.3 ms half-sine) and derates linearly above 25 °C ambient, with maximum junction temperature of 150 °C. Its low incremental surge resistance enables effective clamping even during high-current transients such as ISO 7637-2 Pulse 1 and Pulse 2b in automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.0 V - Maximum continuous reverse operating voltage before significant leakage; sets upper limit for protected line DC bias. |
| VBR min/max | 10.0 V / 11.1 V at 1 mA - Confirmed breakdown range ensures reliable turn-on without premature conduction. |
| VC @ IPPM | 15.4 V at 10 A (10/1000 µs) - Clamping voltage defines worst-case overvoltage seen by protected IC during surge. |
| PPPM | 1000 W - Peak pulse power handling capacity determines survivability against standardized transients like IEC 61000-4-5. |
| ID @ VWM | <1.0 µA - Ultra-low reverse leakage preserves signal integrity and minimizes standby power loss. |
| TJ max | 150 °C - Enables operation in under-hood automotive environments and industrial enclosures with limited airflow. |
| RθJA | 72 °C/W - Thermal resistance measured on 0.2" × 0.2" copper pads; guides minimum PCB copper area for thermal management. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ9.0A-E3/5B | Same DO-214AA package and 9.0 V VWM, but rated for 600 W PPPM (vs. 1000 W); lower clamping voltage (14.5 V). | Limited to lower-energy transients (e.g., IEC 61000-4-2 ESD only); not suitable for ISO 7637-2 Pulse 5a. | Select SMBJ9.0A-E3/5B only if system-level surge testing confirms <600 W requirement and tighter clamping is prioritized. |
| SMCJ9.0AHE3/5B | DO-214AB (SMC) package, same 9.0 V VWM and 1000 W rating, but higher thermal mass and RθJA = 35 °C/W. | Better thermal performance under sustained surge duty; larger footprint requires layout revision. | Choose SMCJ9.0AHE3/5B when board space allows and junction temperature rise must be minimized during repeated surges. |
Compared with SMBJ9.0A-E3/5B, SMB10J9.0HE3/5B delivers 67% higher surge power handling for automotive-grade robustness; versus SMCJ9.0AHE3/5B, it trades thermal efficiency for compact SMB footprint-critical for space-constrained sensor modules.

The SMB10J9.0HE3/5B exhibits a maximum clamping voltage (VC) of 15.4 V when subjected to a 10 A peak pulse current with a 10/1000 µs waveform. This value is measured under standardized test conditions (TA = 25 °C, mounted on 0.2" × 0.2" copper pads) and is specified in the "Electrical Characteristics" table on page 2 of the Vishay datasheet 88422. This clamping level protects downstream ICs with 16 V absolute maximum ratings.
Can SMB10J9.0HE3/5B be used in lead-free reflow processes?
Yes - SMB10J9.0HE3/5B is rated MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C, fully compatible with standard lead-free soldering profiles.
