Product details
Overview
SMBJ13AHE3_A/I 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), used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the SMBJ13AHE3_A/I datasheet, SMBJ13AHE3_A/I pinout, SMBJ13AHE3_A/I application, or SMBJ13AHE3_A/I equivalent, this device is selected for robust ESD and surge protection where low clamping voltage, fast response (<1 ns), and AEC-Q101 qualification are required in automotive and industrial control modules.
Technical Context
This unidirectional TVS diode operates as a reverse-biased avalanche clamp: under normal conditions it presents high impedance above 13 V, then rapidly transitions to low-impedance conduction when transient voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance and long-term reliability under repetitive surge stress.
Designed for PCB-level protection of DC power rails and low-speed signal lines, SMBJ13AHE3_A/I delivers 21.5 V clamping at 27.9 A (10/1000 µs), with 1.0 µA max reverse leakage at VWM and thermal resistance RθJA = 100 °C/W - enabling operation up to +150 °C junction temperature in compact layouts with minimal copper pad area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 13 V - maximum continuous reverse voltage before significant leakage; sets operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 14.4–15.9 V at 1 mA - defines precise avalanche initiation point for predictable transient response |
| VC (Clamping Voltage) | 21.5 V at IPPM = 27.9 A - limits downstream voltage stress during 600 W surge events |
| PPPM (Peak Pulse Power) | 600 W (10/1000 µs) - supports IEC 61000-4-5 Level 4 surge immunity without degradation |
| IR (Reverse Leakage) | 1.0 µA max at VWM - ensures negligible standby power loss and signal integrity on protected lines |
| TJ max | +150 °C - enables deployment in under-hood automotive ECUs and industrial motor drives |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, cathode-indicated by band. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H). Matte tin-plated leads, MSL Level 1, compatible with lead-free reflow (peak 260 °C).
| Pin/Terminal | Circuit Role | Design Meaning |

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_A/I | Halogen-free, RoHS-compliant variant with identical electrical specs and AEC-Q101 qualification | No functional difference; selected where halogen-free materials are mandated (e.g., EU industrial equipment) | Direct material substitution when halogen-free compliance is required; same footprint and thermal performance |
| SMCJ13AHE3_A/I | Same VWM/VBR/VC but in larger SMC (DO-214AB) package; 1500 W PPPM rating | Used where higher surge energy handling (>600 W) is needed, e.g., outdoor telecom enclosures or EV charging stations | Choose only if system-level surge testing exceeds 600 W; requires PCB layout change due to larger 7.11 mm × 6.22 mm footprint |
Compared with SMBJ13AHE3_A/I, SMBJ13AHM3_A/I offers identical protection performance with halogen-free construction, while SMCJ13AHE3_A/I provides higher surge capacity at the cost of board space - making the original SMBJ13AHE3_A/I optimal for space-constrained automotive and industrial modules requiring AEC-Q101 validation.

FAQ
What is the clamping voltage of SMBJ13AHE3_A/I at its rated peak pulse current?
The SMBJ13AHE3_A/I has a maximum clamping voltage (VC) of 21.5 V at its rated peak pulse current (IPPM) of 27.9 A, measured using the standard 10/1000 µs double-exponential waveform. This value ensures protected downstream components - such as microcontrollers or gate drivers - remain within their absolute maximum voltage ratings during surge events. The SMBJ13AHE3_A/I achieves this clamping performance while maintaining low incremental surge resistance and sub-nanosecond response time.
Is SMBJ13AHE3_A/I suitable for automotive applications?
Yes, SMBJ13AHE3_A/I is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3", which denotes automotive-grade reliability testing including temperature cycling, highly accelerated life testing (HALT), and ESD robustness. It is deployed in automotive body control modules, lighting drivers, and sensor interfaces where sustained operation from −40 °C to +125 °C ambient and immunity to load dump transients are required. The SMBJ13AHE3_A/I meets these demands with its 150 °C max junction temperature and validated surge performance.
How does the HE3 suffix differ from E3 or M3 in SMBJ13AHE3_A/I?
The "HE3" suffix in SMBJ13AHE3_A/I indicates RoHS-compliant construction with AEC-Q101 qualification, whereas "E3" denotes commercial-grade RoHS compliance only, and "HM3" adds halogen-free material content alongside AEC-Q101. All three share identical electrical characteristics and SMB package dimensions, but only HE3 and HM3 are approved for automotive use. The SMBJ13AHE3_A/I is therefore specified for applications requiring both regulatory compliance and automotive reliability validation.
What is the reverse leakage current specification for SMBJ13AHE3_A/I at its stand-off voltage?
SMBJ13AHE3_A/I specifies a maximum reverse leakage current (ID) of 1.0 µA at its 13 V stand-off voltage (VWM), tested at TA = 25 °C. This low leakage ensures minimal power loss in always-on circuits and preserves signal integrity on high-impedance sensor lines. At elevated temperatures (e.g., 85 °C), leakage remains well below 10 µA, supporting reliable operation in thermally demanding environments like engine compartments or enclosed industrial controls - a key design attribute of the SMBJ13AHE3_A/I.
Can SMBJ13AHE3_A/I be used in bidirectional configurations?
No, SMBJ13AHE3_A/I is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., SMBJ13CA). Using SMBJ13AHE3_A/I in a bidirectional application would result in forward conduction during negative transients, potentially damaging the device or failing to suppress. For symmetrical surge protection, select SMBJ13CAHE3_A/I instead - the SMBJ13AHE3_A/I is strictly intended for DC rail or single-polarity signal line protection.
