Product details
Overview
SMB10J13AHM3_A/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on DC power rails and signal lines. It features a 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR), 21.5 V clamping voltage (VC) at 46.5 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial power supply inputs.
For engineers reviewing the SMB10J13AHM3_A/H datasheet, SMB10J13AHM3_A/H pinout, SMB10J13AHM3_A/H application, or SMB10J13AHM3_A/H equivalent, key selection criteria include AEC-Q101 qualification, low clamping ratio (VC/VWM ≈ 1.65), unidirectional polarity with cathode band marking, 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: under normal conditions it presents <1.0 µA reverse leakage at 13 V; during transients exceeding VBR, it avalanches to clamp voltage at ≤21.5 V while diverting up to 46.5 A (10/1000 µs). Its glass-passivated junction ensures stable breakdown and low incremental surge resistance.
Thermally, it supports operation from −55 °C to +150 °C junction temperature, with RθJA = 72 °C/W and RθJL = 20 °C/W. The halogen-free, RoHS-compliant HM3 suffix confirms AEC-Q101 qualification and JESD201 Class 2 whisker resistance - critical for automotive under-hood and ADAS module deployments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - maximum continuous reverse operating voltage before significant leakage; defines safe DC rail margin for 12 V automotive systems. |
| VBR min/max | 14.4 V / 15.9 V at 1.0 mA - tight breakdown tolerance ensures predictable turn-on across temperature and production lot. |
| VC @ IPPM | 21.5 V at 46.5 A - clamping voltage limits downstream IC stress during ISO 7637-2 Pulse 1/2a/5a surges. |
| PPPM | 1000 W (10/1000 µs) - sustains high-energy transients without failure; derates linearly above 25 °C ambient. |
| ID @ VWM | ≤1.0 µA - negligible standby power loss and minimal impact on high-impedance sensor bias networks. |
| Package | SMB (DO-214AA) - industry-standard surface-mount outline with 5.59 mm × 4.06 mm footprint and 2.20 mm height for compact PCB layout. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HAST, and mechanical shock per AEC standard. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads solderable per J-STD-002 and JESD22-B102; cathode indicated by color band on one end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection to protected circuit ground or return path | Connected to system GND or low-impedance return; enables shunt clamping of positive transients on the cathode side. |
| Cathode | High-side connection to protected line (e.g., 12 V rail or signal) | Placed upstream of load; conducts avalanche current during overvoltage events to clamp voltage at VC. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood use including thermal cycling, humidity, and vibration - eliminates requalification effort for Tier 1 suppliers. |
| Halogen-free & RoHS-compliant (HM3) | Meets ELV and RoHS directives without compromising surge robustness; supports green manufacturing and export compliance. |
| Low clamping ratio (VC/VWM = 1.65) | Minimizes overvoltage stress on downstream MOSFETs or CAN transceivers during load dump events. |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without pre-baking; reduces assembly cost and process complexity. |
| Glass-passivated junction | Ensures stable VBR over lifetime and immunity to moisture-induced parameter drift in humid environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A-E3/52 | Same VWM (13 V), VBR (14.4–15.9 V), and PPPM (1000 W), but commercial-grade (non-AEC-Q101) and RoHS-compliant only (not halogen-free). | Lacks automotive qualification; suitable for industrial or consumer applications where AEC-Q101 is not mandated. | Select when cost sensitivity outweighs automotive reliability requirements and halogen-free material is not required. |
| SMCJ13A-HM3_A/H | Same AEC-Q101/halogen-free spec, but larger SMC (DO-214AB) package with higher PPPM (1500 W) and lower VC (21.2 V at 71.4 A). | Better suited for higher-energy surges (e.g., ISO 16750-2); requires larger PCB area and different pad layout. | Choose when system-level surge testing exceeds 1000 W or when lower clamping voltage is prioritized over board space. |
Compared with SMBJ13A-E3/52, SMB10J13AHM3_A/H adds AEC-Q101 and halogen-free compliance without sacrificing electrical specs; versus SMCJ13A-HM3_A/H, it trades 500 W surge capacity for 30% smaller footprint and identical clamping performance at rated current.

FAQ
What is the clamping voltage of SMB10J13AHM3_A/H at its rated peak pulse current?
The SMB10J13AHM3_A/H has a maximum clamping voltage (VC) of 21.5 V when subjected to its peak pulse current (IPPM) of 46.5 A under the standard 10/1000 µs waveform. This value is measured at TA = 25 °C with specified mounting conditions (0.2" × 0.2" copper pads), and represents the upper voltage limit imposed on the protected circuit during surge events. The SMB10J13AHM3_A/H maintains this clamping performance across its qualified operating temperature range.
Is SMB10J13AHM3_A/H suitable for automotive applications?
Yes, SMB10J13AHM3_A/H is AEC-Q101 qualified and manufactured with halogen-free, RoHS-compliant materials (HM3 suffix), making it suitable for automotive applications including engine control units, ADAS sensors, and body electronics. Its thermal rating (TJ max = 150 °C), MSL Level 1 reflow compatibility, and validated reliability testing confirm readiness for under-hood and cabin environments. The SMB10J13AHM3_A/H meets automotive surge immunity standards such as ISO 7637-2 when properly implemented.
What does the "HM3" suffix indicate in SMB10J13AHM3_A/H?
The "HM3" suffix in SMB10J13AHM3_A/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification - distinguishing it from commercial-grade variants like "E3" or "M3". It confirms compliance with JESD201 Class 2 whisker resistance, LF peak reflow temperature of 260 °C (MSL Level 1), and material restrictions per EU RoHS Directive and ELV requirements. This makes the SMB10J13AHM3_A/H appropriate for environmentally regulated and safety-critical deployments.
How does SMB10J13AHM3_A/H compare to SMBJ13A in terms of surge handling?
SMB10J13AHM3_A/H and SMBJ13A share identical electrical parameters - VWM = 13 V, VBR = 14.4–15.9 V, VC = 21.5 V, and PPPM = 1000 W - but differ in qualification and material content. The SMB10J13AHM3_A/H carries AEC-Q101 certification and halogen-free construction (HM3), whereas SMBJ13A is commercial-grade (E3/M3). Both use the same SMB package and thermal characteristics, so PCB layout is interchangeable - but only SMB10J13AHM3_A/H satisfies automotive production requirements.
What is the recommended PCB pad layout for SMB10J13AHM3_A/H?
The recommended PCB pad layout for SMB10J13AHM3_A/H consists of 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads connected to each terminal, as specified in the Vishay datasheet (Document Number 88422). This layout ensures optimal thermal dissipation and surge current handling, supporting the full 1000 W PPPM rating. Smaller pads will derate power capability and increase junction temperature; thermal vias to inner ground planes are advised for sustained surge duty cycles. The SMB10J13AHM3_A/H footprint matches standard DO-214AA land patterns used in IPC-7351B.
