Product details
Overview
SMBG13HE3/5B from Vishay General Semiconductor is a uni-directional transient voltage suppressor (TVS) diode in DO-215AA (SMBG) package, designed for clamping inductive switching transients and ESD events on power and signal lines. It features 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR) at 1 mA, 27.9 A peak pulse current (IPPM), 21.5 V clamping voltage (VC) at IPPM, and 600 W peak pulse power (10/1000 µs waveform).
For engineers reviewing the SMBG13HE3/5B datasheet, SMBG13HE3/5B pinout, SMBG13HE3/5B application, or SMBG13HE3/5B equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamping protection device in series with sensitive downstream circuitry, conducting only when reverse voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable leakage performance and fast response (<1 ns), while the DO-215AA package provides robust thermal dissipation (RθJA = 100 °C/W) under repetitive surge conditions.
The SMBG13HE3/5B is rated for 100 A non-repetitive forward surge (8.3 ms half-sine), supports 1.0 µA max reverse leakage at VWM, and meets J-STD-020 MSL Level 1 with 260 °C reflow peak. Its AEC-Q101 qualification confirms suitability for automotive power line and sensor interface protection where reliability under thermal cycling and mechanical stress is critical.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A-E3/5B | Same VWM (13 V), but lower PPPM (400 W) and higher VC (21.5 V → 23.2 V at same IPPM) | Limited to lower-energy transients; not AEC-Q101 qualified | Select SMBG13HE3/5B when automotive qualification or 600 W surge margin is required |
| 1.5SMC13A | Same VWM and VC, but DO-214AB (SMC) package - larger footprint and higher RθJA (110 °C/W) | Requires more PCB area; less suitable for dense automotive modules | Choose SMBG13HE3/5B for space-constrained AEC-Q101 designs needing SMBG footprint and thermal performance |
Compared with SMBJ13A-E3/5B and 1.5SMC13A, the SMBG13HE3/5B delivers higher surge power headroom, automotive-grade reliability, and superior thermal resistance in a smaller DO-215AA package - making it optimal for next-generation ECUs and compact industrial controllers.

FAQ
What is the maximum clamping voltage of SMBG13HE3/5B at its rated peak pulse current?
The SMBG13HE3/5B has a maximum clamping voltage (VC) of 21.5 V when subjected to its rated peak pulse current (IPPM) of 27.9 A using a 10/1000 µs waveform. This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBG13HE3/5B maintains this clamping performance across its full operating temperature range.
Is SMBG13HE3/5B suitable for automotive applications?
Yes, SMBG13HE3/5B is AEC-Q101 qualified and specifically designed for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. Its construction includes glass-passivated junctions, MSL Level 1 reflow compatibility, and guaranteed operation from –55 °C to +150 °C. The HE3 suffix explicitly denotes AEC-Q101 compliance, distinguishing it from commercial-grade E3 variants.
What does the "HE3" suffix indicate in SMBG13HE3/5B?
The "HE3" suffix in SMBG13HE3/5B indicates two key attributes: "H" denotes AEC-Q101 qualification, and "E3" signifies RoHS-compliant, matte tin-plated leads meeting JESD 201 Class 2 whisker resistance. This distinguishes SMBG13HE3/5B from non-automotive SMBG13A-E3/5B variants and confirms its suitability for mission-critical automotive deployments where long-term reliability under thermal and mechanical stress is mandatory.
How does SMBG13HE3/5B differ from bi-directional TVS diodes like SMBG13CA?
SMBG13HE3/5B is a uni-directional TVS diode intended for DC line protection where polarity is fixed, such as 12 V power rails. In contrast, SMBG13CA is bi-directional and used on AC or floating signal lines like RS-485 or CAN bus. The SMBG13HE3/5B exhibits forward conduction below ~0.7 V and clamps only in reverse, whereas SMBG13CA clamps symmetrically in both directions - making them functionally incompatible without circuit redesign.
What is the recommended PCB pad layout for SMBG13HE3/5B?
Vishay specifies a minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad for each terminal of SMBG13HE3/5B to achieve rated thermal and surge performance. This layout ensures adequate heat spreading during 600 W pulse events and supports the specified RθJA of 100 °C/W. Deviating from this pad size may reduce surge current capability and increase junction temperature beyond the 150 °C limit.
