Product details
Overview
SMBJ13AHE3_B/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping inductive switching transients and lightning-induced surges on power and signal lines. It features 13 V stand-off voltage (VWM), 21.5 V maximum clamping voltage at 27.9 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform.
For engineers reviewing the SMBJ13AHE3_B/H datasheet, SMBJ13AHE3_B/H pinout, SMBJ13AHE3_B/H application, or SMBJ13AHE3_B/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 150 °C max junction temperature, and compatibility with automated SMT placement on consumer, industrial, and automotive PCBs.
Technical Context
This TVS diode operates as a voltage-clamping protection device placed in parallel with sensitive circuit nodes. Its glass-passivated junction enables fast response (<1 ns) to transients, while low incremental surge resistance ensures stable clamping performance under repetitive 10/1000 µs pulses at 0.01% duty cycle.
The SMBJ13AHE3_B/H is rated for 100 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine), supports operation from –55 °C to +150 °C, and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak temperature tolerance.
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 nominal systems. |
| VBR min / max | 14.4 V / 15.9 V at 1.0 mA - Breakdown voltage range confirming reliable turn-on above VWM with controlled tolerance. |
| VC @ IPPM | 21.5 V at 27.9 A - Clamping voltage during 10/1000 µs surge; limits downstream voltage stress to ≤21.5 V under worst-case transient. |
| PPPM | 600 W - Peak pulse power handling capability; supports robust protection against IEC 61000-4-5 Level 4 surges when properly mounted. |
| ID @ VWM | 1.0 µA - Reverse leakage at stand-off voltage; negligible power loss and minimal impact on high-impedance sensor or bias networks. |
| TJ max | +150 °C - Maximum junction temperature; enables use in under-hood automotive and high-ambient industrial environments. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 5.21 mm × 4.06 mm footprint and 2.20 mm height; compatible with IPC-7351B land patterns. |
Pinout & Package
Package: SMB (DO-214AA), unidirectional configuration with cathode indicated by molded band. Terminals are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, and qualified to JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink node | Connected to protected line (e.g., 12 V rail); conducts surge current to ground during overvoltage events. |
| Anode | Reference/ground return path | Typically tied to system ground plane; completes clamping path with minimal inductance for effective transient suppression. |
Key Features
| Feature | Design Value |
|---|---|

| 600 W peak pulse power (10/1000 µs) | Withstands repeated high-energy transients without degradation when mounted on 5.0 mm × 5.0 mm copper pads per JEDEC standard. |
| Low clamping ratio (VC/VBR ≈ 1.35) | Ensures tight voltage limiting-critical for protecting 13.3 V–15 V tolerant ICs such as CAN transceivers and microcontroller I/Os. |
| MSL Level 1, 260 °C peak reflow | Enables single-pass lead-free reflow assembly without moisture-related popcorning or delamination risk. |
| Glass passivated junction | Provides stable breakdown characteristics and long-term reliability under thermal and electrical stress in harsh environments. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Guarding |

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_B/H | Halogen-free, RoHS-compliant variant with identical electrical specs and AEC-Q101 qualification. | No functional difference; selected where halogen-free material compliance is mandated (e.g., EU automotive Tier 1 supply chain). | Direct drop-in replacement if halogen-free requirement applies; same footprint, thermal, and electrical behavior. |
| SMBJ13A-E3/52 | Commercial-grade (non-AEC-Q101), same VWM/VC/PPPM, but rated only for –55 °C to +150 °C without automotive qualification testing. | Suitable for cost-sensitive industrial or consumer applications where automotive reliability validation is not required. | Lower-cost alternative for non-automotive designs; verify system-level reliability testing if used in mission-critical roles. |
Compared with SMBJ13AHE3_B/H, the HM3 variant adds halogen-free compliance without trade-offs, while the E3/52 version removes AEC-Q101 validation-making it viable for commercial use but unsuitable for automotive deployment without additional qualification.

FAQ
What is the clamping voltage of SMBJ13AHE3_B/H under a 10/1000 µs surge?
The SMBJ13AHE3_B/H has a maximum clamping voltage (VC) of 21.5 V at 27.9 A peak pulse current with a 10/1000 µs waveform. This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuitry during transient events. The SMBJ13AHE3_B/H maintains this clamping performance across its specified operating temperature range when mounted per recommended pad layout.
Is SMBJ13AHE3_B/H suitable for automotive applications?
Yes, SMBJ13AHE3_B/H is AEC-Q101 qualified and explicitly designated for automotive use with suffix "HE3". It undergoes rigorous stress testing-including temperature cycling, highly accelerated life testing (HALT), and ESD verification-to ensure reliability in under-hood and chassis-mounted electronic control units. The SMBJ13AHE3_B/H meets automotive-grade requirements for surge immunity, thermal stability, and long-term parametric consistency.
What does the "_B/H" suffix mean in SMBJ13AHE3_B/H?
The "_B/H" suffix in SMBJ13AHE3_B/H indicates packaging configuration: "H" denotes 7-inch plastic tape-and-reel packaging with 750 units per reel, and "B" refers to the revision level of the manufacturing process or test specification. This ordering code aligns with Vishay's standardized format for AEC-Q101-qualified SMBJ devices and ensures traceability to qualified production lots.
How does SMBJ13AHE3_B/H differ from bidirectional variants like SMBJ13CA?
SMBJ13AHE3_B/H 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, offering symmetrical clamping for AC or floating signal lines. The SMBJ13AHE3_B/H exhibits forward voltage drop (~3.5 V at 50 A) and reverse leakage <1.0 µA at 13 V, whereas SMBJ13CA has no defined forward direction and double the ID limit for VWM ≤10 V models.
What is the thermal resistance of SMBJ13AHE3_B/H, and how does it affect layout?
The SMBJ13AHE3_B/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on minimum recommended pad layout, and 20 °C/W junction-to-lead (RθJL). To maintain safe junction temperatures under sustained power dissipation, PCB layout must use ≥5.0 mm × 5.0 mm copper pads per terminal as specified in the datasheet. Reducing pad area increases RθJA and risks thermal runaway during repetitive surges.
