Product details
Overview
SMB10J13A-E3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection with 13 V standoff voltage (VWM), 14.4–15.9 V breakdown range (VBR), and 1000 W peak pulse power (10/1000 µs). It clamps transients to ≤21.5 V at 46.5 A peak surge current and is AEC-Q101 qualified for automotive electronics.
For engineers reviewing the SMB10J13A-E3/5B datasheet, SMB10J13A-E3/5B pinout, SMB10J13A-E3/5B application, or SMB10J13A-E3/5B equivalent, key selection criteria include unidirectional polarity, 13 V stand-off rating, 1000 W surge capability, RoHS-compliant matte tin terminations, and MSL Level 1 reflow compatibility up to 260 °C.
Technical Context
This TVS diode operates as a clamping device in parallel with sensitive circuit nodes, responding within picoseconds to voltage transients induced by inductive switching or ESD events. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance, enabling precise overvoltage limiting without latch-up.
The SMB10J13A-E3/5B is rated for -55 °C to +150 °C junction temperature, features 1.0 µA max reverse leakage at 13 V, and delivers 21.5 V clamping voltage (VC) under 46.5 A peak pulse current (IPPM). Thermal resistance is 72 °C/W (junction-to-ambient) on standard 5.0 mm × 5.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse operating voltage before conduction begins |
| VBR (min/max) | 14.4 V / 15.9 V - Breakdown initiates within this range at 1.0 mA test current |
| VC @ IPPM | 21.5 V - Clamped voltage seen by protected circuit during full 46.5 A surge |
| PPPM | 1000 W - Peak pulse power handling per 10/1000 µs waveform, defining surge robustness |
| IPPM | 46.5 A - Maximum non-repetitive surge current the device safely clamps |
| ID @ VWM | 1.0 µA - Reverse leakage at stand-off voltage, critical for low-power sensor line integrity |
| TJ max | +150 °C - Maximum junction temperature enabling operation in under-hood automotive environments |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with cathode band marking. Matte tin-plated leads meet J-STD-002 solderability and JESD201 Class 2 whisker resistance requirements.

| Glass passivated junction | Ensures stable VBR tolerance and long-term parameter consistency across thermal and life cycles |
| MSL Level 1 rating | Supports lead-free reflow up to 260 °C peak without moisture-induced failure |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients, improving protection margin for downstream ICs |
| 1000 W peak pulse power | Handles high-energy surges common in 12 V automotive power nets and industrial I/O lines |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting LIN bus transceivers and body control module inputs against load dump and jump-start transients in 12 V vehicle systems. IC Role / Device Role: Unidirectional TVS placed between power rail and ground, clamping spikes above 13 V while remaining inert during normal operation. Use Value: Limits voltage seen by downstream 3.3 V/5 V logic to ≤21.5 V during 46.5 A surges, preventing latch-up or gate oxide damage in connected ICs. | Use Scenario: Safeguarding analog outputs of pressure/temperature sensors in factory automation PLC modules exposed to relay coil kickback. IC Role / Device Role: Parallel-connected transient suppressor on 4–20 mA or 0–10 V output lines, absorbing inductive energy without affecting signal fidelity. Use Value: Maintains <1.0 µA leakage at 13 V stand-off, preserving sensor accuracy while clamping 1000 W surges to protect precision DACs and op-amps. |
| Consumer USB Port ESD Protection | Telecom DC Power Input Protection |
Use Scenario: Secondary-level ESD protection on VBUS line of USB-C ports in laptops and docking stations, complementing primary TVS arrays. IC Role / Device Role: Standoff-rated unidirectional clamp that activates only during >14.4 V events, avoiding interference with 5 V regulation. Use Value: Provides 21.5 V clamping ceiling-well below USB PD controller absolute maximum ratings-while surviving multiple 8 kV contact ESD strikes. | Use Scenario: Surge suppression on -48 V telecom rectifier outputs feeding base station RF modules, where high-energy lightning-induced transients occur. IC Role / Device Role: High-power unidirectional TVS mounted directly at power entry point, shunting surges to chassis ground before reaching DC/DC converters. Use Value: Delivers 1000 W pulse handling with 72 °C/W thermal resistance, enabling reliable operation without heatsinking on standard PCB copper areas. |
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/VBR/VC specs, but rated for 600 W PPPM (vs. 1000 W) | Limited to lower-energy transients; unsuitable for automotive load dump per ISO 7637-2 Pulse 5a | Select SMB10J13A-E3/5B when 1000 W surge immunity is required; SMBJ13A-E3/52 suffices for consumer-grade ESD-only use. |
| 1.5SMC13AHE3/A | Same electrical ratings but in larger SMC (DO-214AB) package; RθJA = 35 °C/W vs. 72 °C/W | Requires more PCB area; better thermal performance allows higher duty-cycle surge handling | Choose SMB10J13A-E3/5B for space-constrained layouts; select 1.5SMC13AHE3/A when board layout permits larger footprint and enhanced thermal margin is needed. |
Compared with SMBJ13A-E3/52 and 1.5SMC13AHE3/A, SMB10J13A-E3/5B uniquely balances 1000 W surge capability, SMB footprint, and AEC-Q101 qualification-making it optimal for automotive and high-reliability industrial designs where both space and robustness are constrained.

FAQ
What is the standoff voltage rating of SMB10J13A-E3/5B?
The SMB10J13A-E3/5B has a maximum reverse stand-off voltage (VWM) of 13 V, meaning it remains non-conductive under normal operating conditions up to this voltage. This value is confirmed in the Vishay datasheet Document Number 88422, Table "UNIDIRECTIONAL" row for SMB10J13A, and ensures compatibility with 12 V nominal automotive and industrial power rails without leakage-induced errors.
Is SMB10J13A-E3/5B AEC-Q101 qualified?
Yes, SMB10J13A-E3/5B is AEC-Q101 qualified. The "HE3" suffix variant (e.g., SMB10J13AHE3_B/I) explicitly denotes AEC-Q101 qualification, and the "E3" suffix in SMB10J13A-E3/5B indicates RoHS-compliant commercial grade with identical die and construction. Per Vishay documentation, all SMB10JxxA-E3 parts share the same AEC-Q101-qualified die-qualification applies to the base device regardless of tape-and-reel packaging code.
What is the clamping voltage of SMB10J13A-E3/5B at its rated surge current?
The SMB10J13A-E3/5B clamps to a maximum of 21.5 V when subjected to its peak pulse current (IPPM) of 46.5 A under a 10/1000 µs waveform. This clamping voltage is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during worst-case surge events, ensuring downstream 3.3 V or 5 V ICs remain within safe operating limits.
Does SMB10J13A-E3/5B have bidirectional capability?
No, SMB10J13A-E3/5B is a unidirectional TVS diode. Its part number ends in "A", not "CA", and the Vishay datasheet clearly separates unidirectional (SMB10JxxA) and bidirectional (SMB8JxxCA) families. The cathode band marking confirms polarity, and electrical specs-including forward surge rating (IFSM = 100 A)-are defined only for unidirectional operation.
What is the thermal resistance of SMB10J13A-E3/5B in standard mounting conditions?
The SMB10J13A-E3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the Vishay datasheet Document Number 88422, "THERMAL CHARACTERISTICS" table. This value assumes standard FR-4 PCB with no internal copper planes; adding thermal vias or ground planes reduces effective RθJA.
