Product details
Overview
SMB10J13AHE3_A/I 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), 13 V stand-off voltage (VWM), and 21.5 V clamping voltage at 46.5 A peak pulse current. It is AEC-Q101 qualified and used to protect automotive sensor signal lines, MOSFET gate drivers, and microcontroller I/O ports against inductive switching transients.
For engineers reviewing the SMB10J13AHE3_A/I datasheet, SMB10J13AHE3_A/I pinout, SMB10J13AHE3_A/I application, or SMB10J13AHE3_A/I equivalent, this device is selected for robust ESD and surge immunity in space-constrained automotive and industrial PCBs where low-profile surface-mount placement, MSL Level 1 reflow compatibility, and stable clamping performance under repetitive surges are required.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: it remains high-impedance below 13 V (VWM), breaks down between 14.4 V and 15.9 V (VBR at 1 mA), and clamps transients to ≤21.5 V at 46.5 A (IPPM). Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1 ns).
Thermally, it features RθJA = 72 °C/W and RθJL = 20 °C/W, enabling reliable operation up to TJ = 150 °C. The matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards, and the device meets UL 94 V-0 flammability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse operating voltage before conduction begins; defines safe signal line bias margin. |
| VBR (min/max) | 14.4 V / 15.9 V at 1 mA - Confirmed breakdown range ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 21.5 V at 46.5 A - Clamping voltage limits downstream IC stress during 10/1000 μs surge; critical for protecting 3.3 V or 5 V logic interfaces. |
| PPPM | 1000 W (10/1000 μs) - Peak surge energy handling capacity suitable for ISO 7637-2 Pulse 1/2a/5a automotive transients. |
| ID @ VWM | ≤1.0 μA - Ultra-low leakage preserves signal integrity and battery life in always-on sensor circuits. |
| TJ max. | +150 °C - Enables deployment in under-hood automotive environments and industrial enclosures without derating. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JEDEC standards. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A-E3/52 | Same VWM (13 V), VC = 21.5 V, but rated for 600 W PPPM (vs. 1000 W); no AEC-Q101 qualification. | Acceptable for commercial-grade consumer or industrial equipment without automotive reliability requirements. | Select when cost sensitivity outweighs automotive qualification and higher surge margin. |
| 1.5SMC13AHE3_A/I | Same AEC-Q101 qualification and VWM, but SMC package (larger footprint, RθJA = 40 °C/W); PPPM = 1500 W. | Better thermal performance in high-ambient environments, but incompatible with SMB-restricted board space. | Choose when board layout allows larger SMC footprint and >1000 W surge margin is needed. |

FAQ
What is the maximum clamping voltage of SMB10J13AHE3_A/I at its rated peak pulse current?
The SMB10J13AHE3_A/I has a maximum clamping voltage (VC) of 21.5 V at its specified peak pulse current (IPPM) of 46.5 A under a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures downstream circuitry remains within safe voltage limits during surge events. The SMB10J13AHE3_A/I maintains this clamping performance across its full operating temperature range of -55 °C to +150 °C.
Is SMB10J13AHE3_A/I suitable for automotive applications?
Yes, SMB10J13AHE3_A/I is AEC-Q101 qualified and explicitly designated for automotive use with the "HE3" suffix indicating RoHS-compliant and AEC-Q101 qualified construction. It meets requirements for temperature cycling, highly accelerated life testing, and ESD robustness per JEDEC standards, making SMB10J13AHE3_A/I appropriate for body electronics, ADAS sensors, and powertrain control units.
What is the standoff voltage (VWM) and why is it important for SMB10J13AHE3_A/I?
The standoff voltage (VWM) of SMB10J13AHE3_A/I is 13 V - the maximum continuous reverse voltage the device can block without significant conduction. This parameter ensures SMB10J13AHE3_A/I remains non-conductive during normal operation of 12 V automotive systems or 13 V nominal rails, preserving signal integrity and minimizing leakage current (<1.0 μA) that could affect low-power sensor bias networks.
Does SMB10J13AHE3_A/I have a defined polarity, and how is it marked?
Yes, SMB10J13AHE3_A/I is a unidirectional TVS diode with defined polarity: the cathode is identified by a visible color band on the SMB (DO-214AA) package body. During PCB layout, the banded end must be connected toward the protected line, and the anode toward ground or reference potential. Incorrect orientation prevents proper clamping and may lead to catastrophic failure under surge conditions.
What packaging and reel options are available for SMB10J13AHE3_A/I?
SMB10J13AHE3_A/I is supplied in 13-inch plastic tape-and-reel format with a base quantity of 3200 units per reel (package code "I"). The "_A/I" suffix confirms this configuration, and the device uses matte tin-plated leads compatible with J-STD-002 solderability standards. Aetrix Electronics supports both standard reel delivery and cut-tape fulfillment for prototyping and low-volume production runs of SMB10J13AHE3_A/I.
