Product details
Overview
SMBJ13AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed to protect sensitive electronics against ESD, lightning-induced surges, and inductive switching transients. It features a 13 V stand-off voltage (VWM), 21.5 V maximum clamping voltage (VC) at 27.9 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 µs waveform).
For engineers reviewing the SMBJ13AHM3_A/H datasheet, SMBJ13AHM3_A/H pinout, SMBJ13AHM3_A/H application, or SMBJ13AHM3_A/H equivalent, this device is selected for robust overvoltage protection on DC power rails, MOSFET gate drivers, and sensor signal lines in industrial control, automotive subsystems, and telecom infrastructure where low clamping voltage and fast response (<1 ns) are critical.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp with a specified breakdown voltage range of 14.4 V to 15.9 V at 1 mA test current (VBR), ensuring reliable triggering above system operating voltage while maintaining low leakage (<1.0 µA at 13 V). Its glass-passivated junction and MSL Level 1 rating support high-reliability automated SMT assembly.
The device delivers 600 W surge capability under standardized 10/1000 µs waveform conditions, with thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), enabling effective power dissipation on standard PCB copper pads (0.2" × 0.2"). Polarity is marked by a cathode band on the SMB package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 13 V - Maximum continuous reverse working voltage before clamping begins; sets upper limit for normal circuit operation. |
| VBR (Breakdown Voltage) | 14.4–15.9 V at 1 mA - Confirmed avalanche onset range; ensures margin above VWM for noise immunity. |
| VC (Clamping Voltage) | 21.5 V at IPPM = 27.9 A - Peak voltage seen by protected circuit during 600 W transient; defines worst-case stress level. |
| PPPM (Peak Pulse Power) | 600 W (10/1000 µs) - Standardized surge energy handling capacity; validated per ANSI/IEEE C62.35. |
| ID (Reverse Leakage) | ≤1.0 µA at 13 V - Minimal standby current draw; preserves efficiency in battery-powered or low-power systems. |
| TJ max. | 150 °C - Maximum junction temperature; supports operation in under-hood automotive or industrial enclosures. |
| Package | SMB (DO-214AA) - Surface-mount outline with 5.59 mm × 4.06 mm footprint; compatible with J-STD-020 reflow profiles. |
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 |
|---|---|---|---|
| SMBJ13AHE3_A/H | RoHS-compliant commercial grade (E3), not halogen-free; same electrical specs and SMB package. | Lacks halogen-free certification; suitable for non-automotive industrial or consumer use where material compliance is less stringent. | Select SMBJ13AHE3_A/H when halogen-free content is not required and cost optimization is prioritized. |
| SMBJ13AHM3_B/I | Identical electrical and mechanical specs; differs only in packaging format (13" reel, 3200 pcs) and revision code (B/I vs A/H). | No functional difference; used interchangeably where volume procurement or tape-and-reel logistics drive selection. | Choose SMBJ13AHM3_B/I for high-volume production runs requiring larger reels and extended supply continuity. |
Compared with SMBJ13AHM3_A/H, the HE3 variant trades halogen-free construction for lower unit cost in non-automotive settings, while the HM3_B/I offers identical performance in a higher-quantity reel format-enabling optimized inventory planning without design change.

FAQ
What is the clamping voltage of SMBJ13AHM3_A/H under maximum rated surge current?
The SMBJ13AHM3_A/H has a maximum clamping voltage (VC) of 21.5 V when subjected to its rated peak pulse current of 27.9 A using the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's datasheet revision 09-Jan-2024, Document Number 88392. The SMBJ13AHM3_A/H maintains this clamping performance across its operational temperature range.
Is SMBJ13AHM3_A/H suitable for automotive applications?
Yes - the HM3 suffix indicates halogen-free, RoHS-compliant construction, and the part is available in AEC-Q101 qualified versions (e.g., SMBJ13AHM3_X with X = B, C, etc.). While SMBJ13AHM3_A/H itself is commercial-grade, its design basis and qualification pathway align with automotive subsystem requirements including BCMs and sensor interfaces. Always verify the specific revision's qualification status via Vishay's official documentation before automotive deployment.
What does the "HM3" suffix mean in SMBJ13AHM3_A/H?
The "HM3" suffix in SMBJ13AHM3_A/H denotes halogen-free, RoHS-compliant construction per JEDEC JESD201 Class 2 whisker testing and Vishay's material categorization standard. It distinguishes the part from E3 (RoHS-compliant but not halogen-free) and HE3/HM3 variants with AEC-Q101 qualification. The "A/H" revision code identifies the specific manufacturing lot and document revision per Vishay's ordering nomenclature.
How does SMBJ13AHM3_A/H compare to SMBJ13AHE3_A/H in terms of performance?
SMBJ13AHM3_A/H and SMBJ13AHE3_A/H share identical electrical characteristics - including VWM = 13 V, VBR = 14.4–15.9 V, VC = 21.5 V, and PPPM = 600 W - and identical SMB (DO-214AA) package dimensions and thermal behavior. The sole difference lies in material composition: HM3 is halogen-free, while E3 is RoHS-compliant but contains halogens. Both meet MSL Level 1 and J-STD-002 solderability standards.
What is the maximum operating temperature for SMBJ13AHM3_A/H?
The SMBJ13AHM3_A/H has a maximum junction temperature (TJ max.) of +150 °C and an operating junction/storage temperature range of –55 °C to +150 °C. This rating enables use in under-hood automotive environments, industrial enclosures, and high-ambient telecom equipment. Derating curves in Figure 2 of the Vishay datasheet show pulse power reduction above 25 °C ambient, with full 600 W capability maintained up to TJ = 25 °C.
