Product details
Overview
SMBG13AHE3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for robust overvoltage protection of sensitive electronics. 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, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive power line and industrial sensor interface protection.
For engineers reviewing the SMBG13AHE3/5B datasheet, SMBG13AHE3/5B pinout, SMBG13AHE3/5B application, or SMBG13AHE3/5B 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 device in series with power or signal lines, activating when transient voltage exceeds VBR to shunt surge current away from downstream ICs. Its glass-passivated junction ensures stable leakage performance and fast response time (<1 ns), while the low Rsurge minimizes clamping overshoot during high-current transients.
The SMBG13AHE3/5B is rated for 100 A non-repetitive forward surge current (8.3 ms half-sine), supports -55 °C to +150 °C operating range, and meets J-STD-020 MSL Level 1 with 260 °C reflow peak - confirming suitability for automotive under-hood and industrial control environments requiring long-term reliability under thermal cycling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC working margin. |
| VBR (min/max) | 14.4 V / 15.9 V at IT = 1 mA - Ensures predictable turn-on threshold with tight tolerance for consistent protection timing. |
| VC @ IPPM | 21.5 V at 27.9 A - Clamping voltage under 600 W 10/1000 µs surge; limits stress on protected MOSFET or MCU I/O. |
| PPPM | 600 W - Peak pulse power handling capability; enables suppression of ISO 7637-2 Pulse 1/2a/5a transients in 12 V systems. |
| IFSM | 100 A - Single half-sine surge rating (8.3 ms); supports protection against load dump events in automotive applications. |
| Junction Temp | -55 °C to +150 °C - Wide thermal range allows deployment in engine control units and industrial motor drives without derating. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including HTOL, TC, and ESD testing per AEC specification. |

| Cathode | Current exit terminal during clamping | Connected to protected line (e.g., 12 V rail or signal input); band-marked end indicates polarity orientation on PCB. |
Key Features
| Feature | Design Value |
|---|---|

| 600 W peak pulse power | Handles high-energy transients such as ISO 7637-2 Pulse 5a (load dump) without degradation, supporting 12 V vehicle architectures. |
| Glass passivated junction | Ensures stable reverse leakage (<1.0 µA at VWM) and long-term parameter stability across temperature and life cycles. |
| Low profile SMBG package | Enables compact layout in space-constrained modules (e.g., ADAS camera ECUs) while maintaining thermal performance via 5.0 mm × 5.0 mm pad design. |
| MSL Level 1 rating | Allows direct placement into standard SMT reflow profiles up to 260 °C peak without baking - reduces manufacturing overhead. |

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 (600 W vs. SMBJ's 600 W), identical SMB package; differs in thermal resistance (RθJA = 100 °C/W same), but not AEC-Q101 qualified. | Not automotive-qualified; suitable for industrial/commercial designs where AEC validation is not required. | Select SMBG13AHE3/5B when AEC-Q101 compliance is mandatory; choose SMBJ13A-E3/5B for cost-sensitive non-automotive applications. |
| 1.5SMC13A | Same electrical specs (VWM = 13 V, VC = 21.5 V), but larger SMC (DO-214AB) package (7.11 mm × 6.22 mm); higher thermal mass but incompatible footprint. | Requires PCB redesign due to larger pad layout and different mounting geometry; used where higher surge repetition is needed. | Choose SMBG13AHE3/5B for space-constrained SMT layouts; select 1.5SMC13A only if board area permits and higher IPPM margin is prioritized. |
Compared with SMBJ13A-E3/5B and 1.5SMC13A, SMBG13AHE3/5B uniquely combines AEC-Q101 qualification, SMBG footprint compatibility, and full 600 W surge capability - making it the preferred choice for automotive Tier-1 suppliers needing drop-in reliability without layout change.

FAQ
What is the maximum clamping voltage of SMBG13AHE3/5B at its rated peak pulse current?
The SMBG13AHE3/5B has a maximum clamping voltage (VC) of 21.5 V at its rated peak pulse current (IPPM) of 27.9 A, measured under the standard 10/1000 µs waveform. This value ensures protected downstream components - such as automotive MCUs or industrial ADCs - experience no more than 21.5 V during surge events, preserving functional safety margins. The SMBG13AHE3/5B maintains this clamping performance across its full operating temperature range.
Is SMBG13AHE3/5B suitable for automotive applications?
Yes, SMBG13AHE3/5B is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. It meets requirements for temperature cycling, humidity bias, and surge endurance per AEC-Q101 Rev D. The SMBG13AHE3/5B is commonly deployed in body control modules, infotainment power supplies, and ADAS sensor interfaces where reliable transient suppression is critical. Its RoHS-compliant HE3 suffix confirms automotive-grade material compliance.
What does the "HE3/5B" suffix indicate in SMBG13AHE3/5B?
The "HE3" suffix denotes RoHS-compliant, AEC-Q101-qualified construction with matte tin-plated leads, while "5B" specifies packaging in 13-inch diameter plastic tape and reel with a base quantity of 3200 units. This configuration ensures compatibility with high-speed pick-and-place equipment and supports extended production runs without manual handling. The SMBG13AHE3/5B suffix set distinguishes it from non-automotive variants like E3/52 or M3/5B.
How does SMBG13AHE3/5B compare to bidirectional TVS diodes like SMBG13CA?
The SMBG13AHE3/5B is unidirectional and intended for DC line protection with defined polarity (cathode band marked), whereas SMBG13CA is bidirectional and used for AC or data-line protection where voltage polarity reverses. SMBG13AHE3/5B offers lower leakage (<1.0 µA at 13 V) and higher surge current capability in one direction, while SMBG13CA provides symmetrical clamping but higher leakage in both directions. Selection depends on circuit topology - SMBG13AHE3/5B is optimal for 12 V power rails.
What is the thermal resistance of SMBG13AHE3/5B, and how does it affect layout design?
The SMBG13AHE3/5B 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 minimum recommended pad layout per Vishay's datasheet; reducing pad size increases thermal impedance and may require derating. For sustained surge duty, designers should maintain the specified pad dimensions and avoid excessive copper isolation to ensure SMBG13AHE3/5B stays within its 150 °C TJ limit.
