Product details
Overview
SMBJ6.0AHE3/5B from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in the SMB (DO-214AA) package, designed for clamping fast-rising ESD and surge transients on power and signal lines. It features a 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 600 W peak pulse power (10/1000 µs), and clamps to ≤10.3 V at 58.3 A peak surge current - deployed in automotive power rail protection and industrial sensor interface circuits.
For engineers reviewing the SMBJ6.0AHE3/5B datasheet, SMBJ6.0AHE3/5B pinout, SMBJ6.0AHE3/5B application, or SMBJ6.0AHE3/5B equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, 100 °C/W junction-to-ambient thermal resistance, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a voltage-clamping device that enters avalanche conduction when reverse voltage exceeds its VBR threshold, limiting transient energy dissipation across protected ICs or MOSFETs. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<800 µA at VWM).
The SMBJ6.0AHE3/5B is rated for repetitive 10/1000 µs surges at 0.01% duty cycle, supports 100 A non-repetitive forward surge (8.3 ms half-sine), and maintains operation from –55 °C to +150 °C junction temperature - meeting MSL Level 1 reflow requirements up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before clamping begins; sets upper limit for normal circuit operation. |
| VBR @ IT = 10 mA | 6.67–7.37 V - Verified breakdown range ensuring reliable turn-on during overvoltage events without premature conduction. |
| VC @ IPPM = 58.3 A | ≤10.3 V - Clamped voltage under full 600 W surge; defines maximum stress imposed on downstream components. |
| PPPM | 600 W - Peak pulse power handling per 10/1000 µs waveform; determines survivability against lightning-induced or inductive-switching transients. |
| IFSM | 100 A - Single half-sine surge rating (8.3 ms); validates robustness against high-energy motor or relay coil turn-off spikes. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; informs derating requirements above 25 °C ambient. |
| TJ max. | +150 °C - Maximum junction temperature; enables use in under-hood automotive and high-temperature industrial environments. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode indicated by band marking; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts avalanche current to ground during overvoltage events. |
| Anode (unbanded end) | Reference node | Typically tied to system ground or lower-potential rail; completes clamping path during reverse-biased surge conditions. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0A-E3/5B | No AEC-Q101 qualification; commercial-grade only; identical electrical specs and SMB package. | Suitable for non-automotive industrial or consumer designs where automotive reliability certification is not required. | Select when cost sensitivity outweighs need for automotive qualification and lifecycle assurance. |
| SMAJ6.0AHE3/A | Lower 400 W PPPM; SMA (DO-214AC) package with smaller footprint and higher RθJA (140 °C/W). | Better suited for space-constrained PCBs with lower surge exposure; requires tighter thermal management. | Choose for compact layouts with moderate surge risk, but avoid in AEC-Q101 or high-power transient environments. |
Compared with SMBJ6.0A-E3/5B and SMAJ6.0AHE3/A, the SMBJ6.0AHE3/5B uniquely combines AEC-Q101 qualification, 600 W surge capability, and SMB thermal performance - making it the preferred choice for automotive and high-reliability industrial power rail protection where both certification and robust clamping are mandatory.

FAQ
What is the clamping voltage of SMBJ6.0AHE3/5B at its rated peak pulse current?
The SMBJ6.0AHE3/5B clamps to a maximum of 10.3 V when subjected to its rated peak pulse current of 58.3 A (10/1000 µs waveform). This value is measured under standardized test conditions with the device mounted on 0.2" × 0.2" copper pads, and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBJ6.0AHE3/5B maintains this clamping performance across its specified operating temperature range.
Is SMBJ6.0AHE3/5B suitable for automotive applications?
Yes, SMBJ6.0AHE3/5B is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation in datasheet 88392. It meets automotive reliability requirements including temperature cycling, humidity testing, and mechanical shock - making it appropriate for engine control units, body electronics, and ADAS power domains. The SMBJ6.0AHE3/5B also complies with MSL Level 1 for lead-free reflow processing.
How does the SMBJ6.0AHE3/5B differ from bidirectional variants like SMBJ6.0CA?
The SMBJ6.0AHE3/5B is unidirectional, meaning it conducts only in reverse bias above VBR, with polarity marked by a cathode band. In contrast, SMBJ6.0CA is bidirectional and symmetrical, suppressing transients in both directions - useful for AC lines or differential signals. The SMBJ6.0AHE3/5B offers lower leakage and higher surge current capability in its intended direction, while SMBJ6.0CA provides balanced clamping but with reduced peak pulse current rating.
What is the thermal resistance of SMBJ6.0AHE3/5B, and how does it affect layout?
The SMBJ6.0AHE3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on minimum recommended 0.2" × 0.2" copper pads per terminal. This value assumes no additional heatsinking; larger copper areas or internal planes reduce RθJA. For continuous power dissipation near its 5.0 W rating, PCB layout must allocate sufficient copper area and consider ambient temperature derating - especially critical in enclosed automotive or industrial enclosures where SMBJ6.0AHE3/5B operates up to +150 °C junction temperature.
Can SMBJ6.0AHE3/5B be used for ESD protection per IEC 61000-4-2?
Yes, SMBJ6.0AHE3/5B responds in sub-nanosecond time and clamps fast ESD transients effectively, though it is optimized for higher-energy 10/1000 µs surges (IEC 61000-4-5). For pure IEC 61000-4-2 ±8 kV contact discharge, its 600 W rating provides substantial margin, but designers should verify layout parasitics and ensure low-inductance grounding. The SMBJ6.0AHE3/5B's 800 µA max reverse leakage at 6.0 V also supports low-power sensor interfaces without loading errors.
