Product details
Overview
SMBJ13AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR) at 1 mA, 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), commonly deployed to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the SMBJ13AHE3_A/H datasheet, SMBJ13AHE3_A/H pinout, SMBJ13AHE3_A/H application, or SMBJ13AHE3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), and compliance with UL 497B for surge protection systems.
Technical Context
This TVS diode operates as a clamping device in parallel with sensitive circuitry, conducting only when reverse voltage exceeds VBR to divert surge energy away from downstream components. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at VWM), while the low incremental surge resistance enables rapid voltage limiting during fast transients.
The SMBJ13AHE3_A/H is rated for repetitive 10/1000 µs surges at 0.01% duty cycle and supports peak forward surge current (IFSM) of 100 A (8.3 ms half-sine). Junction temperature range spans –55 °C to +150 °C, and it meets MSL level 1 per J-STD-020 with 260 °C reflow peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin for 12 V rail protection. |
| VBR (min/max) | 14.4 V / 15.9 V at 1 mA - Confirmed breakdown threshold range; ensures reliable triggering above normal operating voltage. |
| VC @ IPPM | 21.5 V at 27.9 A - Clamped voltage during 600 W surge; limits stress on protected 15 V logic or gate drivers. |
| PPPM | 600 W (10/1000 µs) - Peak transient energy handling capacity; suitable for IEC 61000-4-5 Level 3/4 surge immunity. |
| ID @ VWM | ≤1.0 µA - Ultra-low reverse leakage at stand-off; prevents unnecessary power loss in battery-powered sensor nodes. |
| TJ max. | +150 °C - Maximum junction temperature rating; supports operation in under-hood automotive or high-ambient industrial environments. |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient on standard 0.2" × 0.2" copper pads; informs heatsinking requirements for sustained surge duty. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, matte tin-plated leads, RoHS-compliant and AEC-Q101 qualified. Cathode indicated by band marking on cathode end.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13AHM3_A/H | Halogen-free, RoHS-compliant, AEC-Q101 qualified; identical electrical specs and package. | No functional difference; selected where halogen-free material compliance is mandated (e.g., EU public infrastructure projects). | Direct substitution if halogen-free bill-of-materials is required; same footprint, thermal, and clamping performance. |
| SMBJ13A-E3/52 | Commercial-grade (non-AEC-Q101), same VWM/VBR/VC/PPPM, RoHS-compliant but not automotive-qualified. | Not approved for automotive or mission-critical industrial use; limited to consumer or non-safety-rated equipment. | Lower-cost option for non-automotive designs where AEC-Q101 is not required; verify lifecycle and traceability needs. |
Compared with SMBJ13AHE3_A/H, the HM3 variant adds halogen-free compliance without altering protection performance, while the E3/52 version omits AEC-Q101 validation-making it unsuitable for automotive but viable for cost-sensitive commercial power supplies.

FAQ
What is the clamping voltage of SMBJ13AHE3_A/H at its rated peak pulse current?
The SMBJ13AHE3_A/H has a maximum clamping voltage (VC) of 21.5 V at its rated peak pulse current (IPPM) of 27.9 A, measured using the standardized 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during a 600 W transient event and is critical for ensuring downstream components remain within their absolute maximum ratings. The SMBJ13AHE3_A/H maintains this clamping performance across its full operating temperature range.
Is SMBJ13AHE3_A/H suitable for automotive applications?
Yes, SMBJ13AHE3_A/H is AEC-Q101 qualified and explicitly designated for automotive use, with suffix "HE3" indicating RoHS-compliance and automotive qualification. It undergoes rigorous testing for temperature cycling, high-temperature reverse bias, and mechanical shock-making it appropriate for engine control units, ADAS sensors, and infotainment power rails. The SMBJ13AHE3_A/H meets UL 497B recognition and supports operation from –55 °C to +150 °C junction temperature.
How does the SMBJ13AHE3_A/H differ from bidirectional variants like SMBJ13CA?
The SMBJ13AHE3_A/H is unidirectional, meaning it conducts only in reverse bias above VBR and blocks forward current beyond VF ≈ 3.5 V at 50 A. In contrast, SMBJ13CA is bidirectional and symmetrical-clamping in both polarities with identical VBR in either direction. The SMBJ13AHE3_A/H is used where polarity is known and ground-referenced protection is needed (e.g., 12 V rail to chassis), while SMBJ13CA suits AC-coupled or floating signal lines. They are not interchangeable without circuit redesign.
What is the thermal resistance and how does it affect PCB layout for SMBJ13AHE3_A/H?
The SMBJ13AHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes minimal copper area; increasing pad size or adding internal ground planes reduces RθJA and improves surge endurance. For repeated surge events or high ambient temperatures, designers should allocate ≥250 mm² total copper area per terminal and avoid narrow traces to sustain the 5.0 W steady-state power dissipation rating.
Does SMBJ13AHE3_A/H meet any safety certifications?
Yes, SMBJ13AHE3_A/H is Underwriters Laboratories (UL) recognized under file E136766 for both unidirectional and bidirectional TVS devices, compliant with UL 497B for primary protector classification. It also meets MSL Level 1 per J-STD-020 (peak reflow temperature 260 °C), and its molding compound satisfies UL 94 V-0 flammability rating. These certifications validate its suitability in safety-critical telecom, industrial, and automotive surge protection modules.
