Product details
Overview
SMBJ13AHE3/5B from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in the SMB (DO-214AA) package, designed for robust overvoltage protection of sensitive electronics. It features a 13 V standoff voltage (VWM), 14.4–15.9 V breakdown voltage (VBR) at 1.0 mA test current, and clamps transients to ≤21.5 V at 27.9 A peak pulse current (IPPM) under 10/1000 µs waveform - deployed on power rails and signal lines in industrial sensor interfaces and automotive control modules.
For engineers reviewing the SMBJ13AHE3/5B datasheet, SMBJ13AHE3/5B pinout, SMBJ13AHE3/5B application, or SMBJ13AHE3/5B equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (−55 to +150 °C), and packaging details for tape-and-reel delivery (3200 pcs per 13″ reel).
Technical Context
This TVS diode operates as a clamping device in unidirectional configuration, with cathode-banded polarity marking and glass-passivated junction for stable surge response. Its low incremental surge resistance and fast response time (<1 ns) enable effective suppression of ESD, lightning-induced surges, and inductive switching transients.
The SMBJ13AHE3/5B is rated for 600 W peak pulse power (10/1000 µs), 5.0 W steady-state power dissipation, and 100 A non-repetitive forward surge current (8.3 ms half-sine). It meets MSL Level 1 per J-STD-020 and is AEC-Q101 qualified for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 13 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (Breakdown Voltage) | 14.4–15.9 V at 1.0 mA - guaranteed conduction onset under controlled DC test conditions |
| VC (Clamping Voltage) | ≤21.5 V at IPPM = 27.9 A - limits transient voltage seen by protected IC or MOSFET |
| PPPM (Peak Pulse Power) | 600 W (10/1000 µs) - defines maximum single-event surge energy absorption capability |
| RθJA (Junction-to-Ambient) | 100 °C/W - determines thermal rise under sustained power dissipation; requires adequate PCB copper area |
| TJ Range | −55 to +150 °C - supports operation in under-hood automotive and industrial environments |
| AEC-Q101 Qualified | Yes - validated for automotive electronic systems per stress-test requirements including HTOL, TC, AC/DC |
Pinout & Package

Applications
| Automotive Body Control Module (BCM) | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Protecting LIN bus transceivers and microcontroller I/O pins from load-dump and jump-start induced surges. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between LIN line and ground, triggered only on positive transients. Use Value: Limits voltage to ≤21.5 V during 27.9 A surges, preventing damage to 5 V tolerant transceivers and preserving communication integrity. |
Use Scenario: Safeguarding analog output lines (4–20 mA) of pressure/temperature sensors exposed to motor drive noise. IC Role / Device Role / Timing Role: Standoff-clamp TVS on sensor output rail, absorbing repetitive 10/1000 µs transients from nearby VFDs. Use Value: Maintains signal accuracy by clamping transients below 21.5 V while exhibiting <1 µA leakage at 13 V, minimizing offset error. |
| Power Supply Input Protection (12 V Rail) | USB-C Port ESD Protection |
Use Scenario: Front-end protection for DC-DC converters in telecom power supplies subjected to ISO 7637-2 Pulse 1/2a/5a. IC Role / Device Role / Timing Role: Primary surge clamp on 12 V input, coordinated with upstream fuse and downstream LC filter.

Use Scenario: Secondary-level protection for USB-C CC and VBUS lines against contact ESD (IEC 61000-4-2 ±15 kV air). IC Role / Device Role / Timing Role: Fast-response unidirectional TVS on VBUS line, placed after primary polymer PTC and before buck converter. Use Value: Clamps ESD events within <1 ns to ≤21.5 V, preventing latch-up in USB PD controllers and preserving port functionality. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13AHM3/5B | Halogen-free variant; identical electrical specs and AEC-Q101 qualification | Required where halogen-free compliance is mandated (e.g., EU automotive Tier 1 supply chain) | Select SMBJ13AHM3/5B when material compliance documentation (e.g., IPC-1752) is contractually required |
| SMBJ13A-E3/5B | Commercial-grade (non-AEC-Q101); same VWM, VBR, VC, and PPPM; no automotive qualification testing | Suitable for consumer or industrial applications where extended temperature cycling and HTOL validation are not needed | Choose SMBJ13A-E3/5B for cost-sensitive non-automotive designs with standard reliability requirements |
Compared with SMBJ13AHE3/5B, the HM3 variant adds halogen-free compliance without altering performance, while the E3 variant removes AEC-Q101 validation-making it appropriate for commercial use but unsuitable for automotive deployment where qualification is mandatory.

FAQ
What is the clamping voltage of SMBJ13AHE3/5B at its rated peak pulse current?
The SMBJ13AHE3/5B has a maximum clamping voltage (VC) of 21.5 V at its rated peak pulse current (IPPM) of 27.9 A under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures downstream components see limited overvoltage during surge events. The SMBJ13AHE3/5B maintains this clamping performance across its full operating temperature range.
Is SMBJ13AHE3/5B suitable for automotive applications?
Yes, SMBJ13AHE3/5B is AEC-Q101 qualified, meaning it has passed rigorous stress tests including high-temperature operating life, temperature cycling, and ESD robustness required for automotive electronics. Its −55 to +150 °C junction temperature range and MSL Level 1 rating make it appropriate for under-hood and cabin control modules. The SMBJ13AHE3/5B is explicitly designated for automotive use via its HE3 suffix.
What does the "HE3" suffix indicate in SMBJ13AHE3/5B?
The "HE3" suffix in SMBJ13AHE3/5B denotes RoHS-compliant construction with AEC-Q101 qualification. "H" indicates AEC-Q101 qualification, "E3" confirms RoHS compliance and commercial-grade reliability. This distinguishes it from E3-only (commercial, non-automotive) or HM3 (halogen-free + AEC-Q101) variants. The SMBJ13AHE3/5B meets both environmental and automotive reliability mandates simultaneously.
How does SMBJ13AHE3/5B differ from bidirectional TVS diodes like SMBJ13CA?
SMBJ13AHE3/5B is unidirectional and functions only during positive transients relative to ground, with polarity marked by a cathode band. In contrast, SMBJ13CA is bidirectional and protects against surges of either polarity. The SMBJ13AHE3/5B offers lower leakage (<1.0 µA at 13 V) and is preferred for DC rail protection, whereas SMBJ13CA suits AC-coupled or differential signal lines where polarity reversal occurs.
What PCB layout guidance applies to SMBJ13AHE3/5B for optimal thermal performance?
For optimal thermal performance, mount SMBJ13AHE3/5B on minimum 0.2″ × 0.2″ (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the Vishay datasheet. Use internal or external copper planes connected via multiple vias to reduce RθJA below the nominal 100 °C/W. Avoid narrow traces between SMBJ13AHE3/5B and ground; keep the path short and wide to minimize inductance during surge events.
