Product details
Overview
SMBJ13AHE3_B/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping fast-rising ESD and surge transients on power and signal lines. It features 13 V standoff 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), used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the SMBJ13AHE3_B/I datasheet, SMBJ13AHE3_B/I pinout, SMBJ13AHE3_B/I application, or SMBJ13AHE3_B/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), and compliance with UL 497B for telecom and automotive electronics protection.
Technical Context
This TVS diode operates as a voltage-clamping device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold (VBR), limiting transient energy to safe levels across protected circuit nodes. Its glass-passivated junction ensures stable leakage performance and fast response time (<1 ns), while the low incremental surge resistance supports effective suppression of high-current transients without thermal runaway.
The SMBJ13AHE3_B/I is rated for 100 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine), operates over -55 °C to +150 °C junction temperature range, and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 13 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC bias margin for protected line. |
| VBR (Breakdown Voltage) | 14.4–15.9 V at 1 mA - Confirmed avalanche onset range; ensures reliable triggering above normal operating voltage. |
| VC (Clamping Voltage) | 21.5 V at IPPM = 27.9 A - Peak voltage seen by downstream circuit during 10/1000 µs surge; determines minimum IC survival margin. |
| PPPM (Peak Pulse Power) | 600 W (10/1000 µs) - Sustained transient energy handling capability; validates suitability for IEC 61000-4-5 Level 4 surges. |
| ID (Reverse Leakage) | 1.0 µA max. at VWM - Low leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits. |
| TJ max. | +150 °C - Enables operation in under-hood automotive or enclosed industrial environments without derating. |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient on standard 0.2" × 0.2" copper pads; informs heatsinking requirements. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with cathode band marking. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); matte tin-plated leads; UL 94 V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Surge return path | Connected to ground or low-impedance reference; completes clamping loop during transient events. |
| Cathode | Protected line connection / Surge input | Connected to line being protected (e.g., 12 V rail or sensor output); reverse-biased during normal operation. |
Key Features
| Feature | Design Value |

| MSL Level 1 rating | Enables standard SMT reflow without moisture sensitivity concerns; no baking required prior to assembly. |
| RoHS-compliant & halogen-free option | HE3 suffix denotes RoHS-compliant construction; HM3 variant adds halogen-free epoxy for stringent environmental compliance. |
Applications
| Automotive Body Control Module | Industrial PLC Digital Input |
|---|---|

IC Role / Device Role: Localized TVS mounted adjacent to sensor connector to minimize inductance in clamping path. Use Value: 21.5 V clamping voltage ensures sensor output stays within ADC input range (0–5 V or 0–3.3 V) even during 2 kV EFT bursts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13AHM3_B/I | Halogen-free epoxy variant; identical electrical specs and AEC-Q101 qualification. | No functional difference; selected where halogen-free compliance is mandated (e.g., EU automotive Tier 1). | Direct material substitution when RoHS + halogen-free requirements apply; same footprint and thermal behavior. |
| SMBJ13A-E3/5B | Commercial-grade (non-AEC-Q101), same VWM/VBR/VC/PPPM, but rated only for -55 °C to +150 °C without automotive stress validation. | Suitable for industrial or consumer applications where automotive qualification is not required. | Lower-cost alternative for non-automotive designs; verify system-level reliability testing if deployed in harsh environments. |
Compared with SMBJ13AHE3_B/I, the HM3 variant offers identical protection performance with halogen-free compliance, while the E3/5B version provides cost-efficient commercial-grade protection without AEC-Q101 validation-enabling tiered sourcing based on end-equipment qualification needs.

FAQ
What is the clamping voltage of SMBJ13AHE3_B/I at its rated peak pulse current?
The SMBJ13AHE3_B/I has a maximum clamping voltage (VC) of 21.5 V at its specified peak pulse current (IPPM) of 27.9 A under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during standardized surge events. The SMBJ13AHE3_B/I maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C).
Is SMBJ13AHE3_B/I qualified for automotive applications?
Yes, SMBJ13AHE3_B/I is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation in datasheet 88392 (Revision 09-Jan-2024). This qualification covers stress tests including temperature cycling, humidity bias, and surge endurance, making SMBJ13AHE3_B/I suitable for under-hood and body electronics where automotive reliability standards apply.
What does the "_B/I" suffix indicate in SMBJ13AHE3_B/I?
The "_B/I" suffix in SMBJ13AHE3_B/I denotes packaging configuration: "B" indicates tape-and-reel packaging per Vishay's internal revision coding, and "I" specifies a 13-inch diameter reel containing 3200 units. This matches the preferred package code "I" and base quantity "3200" listed in the Ordering Information table of datasheet 88392.
How does SMBJ13AHE3_B/I differ from bidirectional variants like SMBJ13CA?
SMBJ13AHE3_B/I is unidirectional, with polarity marked by a cathode band and intended for DC line protection where reverse conduction must be blocked. In contrast, SMBJ13CA is bidirectional, symmetric in both directions, and used for AC or differential signal lines. Their VBR and VC values differ: SMBJ13AHE3_B/I has VBR = 14.4–15.9 V (unidirectional), while SMBJ13CA has VBR = 14.4–15.9 V in both directions but no defined anode/cathode polarity.
What is the thermal resistance and maximum power dissipation of SMBJ13AHE3_B/I?
SMBJ13AHE3_B/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads, and a steady-state power dissipation (PD) rating of 5.0 W at TA = 50 °C. These values define its ability to dissipate heat during continuous leakage or repeated low-energy transients, and inform PCB layout decisions such as pad size and copper area allocation.
