Product details
Overview
SMBJ13D-M3/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, with 13 V stand-off voltage (VWM), 14.6–15.7 V breakdown voltage (VBR) at 1 mA, 21.2 V clamping voltage (VC) at 28.3 A peak pulse current, and 600 W peak pulse power rating under 10/1000 μs waveform - deployed for protecting MOSFETs and signal lines in industrial sensor interfaces against inductive switching transients.
For engineers reviewing the SMBJ13D-M3/H datasheet, SMBJ13D-M3/H pinout, SMBJ13D-M3/H application, or SMBJ13D-M3/H equivalent, key selection criteria include verified unidirectional polarity, ±3.5% VBR tolerance, low 0.5 μA reverse leakage at VWM, M3 halogen-free RoHS-compliant construction, and compatibility with automated SMT placement on standard PCB pad layouts.
Technical Context
This TVS diode operates as a clamping device that remains high-impedance below VWM (13 V), then rapidly transitions to low-impedance conduction once VBR (14.6–15.7 V) is exceeded, limiting transient voltages to ≤21.2 V at 28.3 A. Its junction-to-ambient thermal resistance is 125 °C/W on minimum recommended pad layout.
The SMBJ13D-M3/H meets J-STD-020 MSL Level 1, supports 260 °C lead-free reflow, and features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. It is rated for -55 °C to +150 °C operating junction temperature and exhibits very fast response time (<1 ns) to ESD and surge events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - maximum continuous reverse working voltage before clamping initiates |
| VBR min/max | 14.6 V / 15.7 V at 1 mA - tight ±3.5% tolerance ensures predictable turn-on across production lots |
| VC @ IPPM | 21.2 V at 28.3 A - clamping voltage limits downstream IC stress during 10/1000 μs surges |
| PPPM | 600 W - peak pulse power handling per 10/1000 μs waveform, 0.01% duty cycle |
| ID @ VWM | 0.5 μA - ultra-low leakage preserves signal integrity in high-impedance sensor paths |
| Package | SMB (DO-214AA) - industry-standard surface-mount outline with 2.20 mm height and 5.59 mm length |
| Polarity | Unidirectional - cathode indicated by band; blocks reverse current until breakdown threshold |
Pinout & Package
SMBJ13D-M3/H uses the SMB (DO-214AA) surface-mount package: 2-terminal, single-row, gull-wing leads, 2.20 mm max height, 5.59 mm overall length, and designed for soldering on 5.0 mm × 5.0 mm copper pad areas per Vishay's recommended layout.
| Pin/Terminal | Circuit Role | Design Meaning |

| Cathode (banded end) | Reverse-biased clamping terminal | Connected to protected line (e.g., I/O, power rail); conducts when transient exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| ±3.5 % VBR tolerance | Enables precise overvoltage threshold control without design margin inflation |
| 600 W peak pulse power | Handles IEC 61000-4-5 Level 4 surges (4 kV line-earth) on 50 Ω source impedance |
| MSL Level 1 rating | Allows unlimited floor life and single-reflow processing without dry-pack requirements |
| M3 suffix compliance | Halogen-free, RoHS-compliant, and passes JESD 201 Class 2 whisker test for long-term reliability |
| Low 0.5 μA leakage at VWM | Minimizes standby power loss and avoids false triggering in battery-powered sensor nodes |
Applications
| Industrial Sensor Signal Protection | DC Power Rail Clamping |
|---|---|
Use Scenario: Protecting analog output lines (e.g., 4–20 mA, 0–10 V) of pressure/temperature sensors in factory automation cabinets exposed to relay coil flyback. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and ground to clamp transients before they reach ADC input or op-amp buffer. Use Value: Limits induced spikes to ≤21.2 V, preventing latch-up or damage to 3.3 V/5 V signal-chain ICs while adding <0.5 μA leakage. | Use Scenario: Safeguarding 12 V DC input rails of PLC I/O modules subjected to load dump and hot-swap events. IC Role / Device Role / Timing Role: TVS connected anode-to-ground, cathode-to-rail to absorb positive-going surges up to 600 W. Use Value: Clamps rail voltage within safe operating range of downstream regulators and microcontrollers during 10/1000 μs transients. |
| Automotive Body Control Module Interfaces | Telecom Line Interface Protection |
Use Scenario: Shielding LIN bus transceivers and GPIO lines in BCMs from battery transients and ESD during service disconnect. IC Role / Device Role / Timing Role: Unidirectional TVS on each LIN data line referenced to chassis ground, leveraging tight VBR for repeatable trip point. Use Value: Maintains signal fidelity with sub-nanosecond response and prevents system reset due to >13 V excursions on 12 V nominal bus. | Use Scenario: Protecting Ethernet PHY interface pins (e.g., MDI pairs) in VoIP gateways from lightning-induced surges on building wiring. IC Role / Device Role / Timing Role: TVS placed differential-mode between pair and common-mode to ground, using SMB footprint for compact board area. Use Value: Provides 600 W surge immunity without degrading 100 MHz signal integrity, validated per IEC 61000-4-5 Ed.3. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A-M3/5B | Same VWM/VBR/VC specs; differs only in tape-and-reel packaging (5B = 3200-unit 13" reel vs. H = 750-unit 7" reel) | No functional difference; identical electrical and thermal performance | Select based on volume procurement needs and SMT line feeder compatibility |
| SMCJ13A | Higher 1500 W PPPM rating, larger SMC (DO-214AB) package, 100 °C/W RθJA vs. 125 °C/W | Better suited for higher-energy surges but requires 30% more PCB area and different thermal layout | Choose SMBJ13D-M3/H for space-constrained designs where 600 W suffices and SMB footprint is mandated |
Compared with SMBJ13A-M3/5B, SMBJ13D-M3/H offers identical protection performance in identical SMB packaging but with smaller reel quantity; versus SMCJ13A, it trades peak power headroom for compact size and lower thermal resistance in high-density layouts.

FAQ
What is the breakdown voltage range for SMBJ13D-M3/H?
The SMBJ13D-M3/H has a guaranteed breakdown voltage (VBR) range of 14.6 V to 15.7 V at 1 mA test current, corresponding to ±3.5 % tolerance around the nominal 13 V stand-off rating. This tight tolerance ensures consistent clamping behavior across manufacturing lots and simplifies system-level surge margin analysis without overdesign.
Does SMBJ13D-M3/H support lead-free reflow soldering?
Yes, SMBJ13D-M3/H is qualified for lead-free reflow per J-STD-020 MSL Level 1, with a maximum peak temperature of 260 °C. Its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102, enabling reliable solder joint formation in standard SMT processes without pre-baking or special handling.
How does SMBJ13D-M3/H differ from bidirectional variants like SMBJ13CD-M3/H?
SMBJ13D-M3/H is unidirectional, with cathode marked by a band and designed to clamp only positive transients relative to ground. In contrast, SMBJ13CD-M3/H is bidirectional - no polarity marking, symmetric clamping in both directions - making it suitable for AC-coupled or differential signal lines where negative excursions must also be suppressed.
What is the maximum clamping voltage of SMBJ13D-M3/H under surge conditions?
The SMBJ13D-M3/H clamps to a maximum of 21.2 V when subjected to its rated 28.3 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This VC value defines the upper voltage limit imposed on protected circuits during transient events and is critical for ensuring downstream ICs remain within absolute maximum ratings.
Can SMBJ13D-M3/H be used in automotive applications?
Yes, SMBJ13D-M3/H is widely deployed in automotive body control modules and sensor interfaces due to its -55 °C to +150 °C operating junction temperature range, AEC-Q200 alignment via Vishay's industrial-grade qualification, and proven performance against load dump and ISO 7637-2 pulses - provided layout follows Vishay's recommended 5.0 mm × 5.0 mm copper pad for thermal management.
