Product details
Overview
SMBJ6.5AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping fast-rising ESD and surge transients on power and signal lines. It features 6.5 V stand-off voltage (VWM), 7.22–7.98 V breakdown voltage (VBR) at 10 mA, 11.2 V maximum clamping voltage (VC) at 53.6 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFET gates, sensor interfaces, and DC power rails in industrial control systems.
For engineers reviewing the SMBJ6.5AHE3_A/I datasheet, SMBJ6.5AHE3_A/I pinout, SMBJ6.5AHE3_A/I application, or SMBJ6.5AHE3_A/I equivalent, key selection considerations include its AEC-Q101 qualification status, unidirectional polarity with cathode band marking, 150 °C max junction temperature, and compatibility with automated SMT placement on standard PCB pad layouts per JEDEC DO-214AA footprint.
Technical Context
This TVS diode operates as a voltage-clamping protection device that remains high-impedance below VWM = 6.5 V and rapidly transitions to low-impedance conduction above VBR = 7.22–7.98 V to divert transient energy away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<500 µA at VWM).
The SMBJ6.5AHE3_A/I delivers 600 W peak pulse power handling with 10/1000 µs waveform, supports 100 A non-repetitive forward surge current (IFSM), and exhibits 0.061 %/°C temperature coefficient of VBR, enabling predictable clamping performance across -55 °C to +150 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - Maximum continuous reverse working voltage before clamping begins; sets upper limit for normal operation on protected line. |
| VBR @ IT = 10 mA | 7.22–7.98 V - Breakdown voltage range defining reliable turn-on threshold under standardized test conditions. |
| VC @ IPPM = 53.6 A | 11.2 V - Maximum clamped voltage during 600 W transient event; determines worst-case overvoltage seen by protected IC. |
| IPPM | 53.6 A - Peak pulse current capability with 10/1000 µs waveform; defines surge energy absorption capacity. |
| PPPM | 600 W - Peak pulse power rating; enables robust protection against IEC 61000-4-5 Level 3/4 surges when properly mounted. |
| Junction Temp. Range | -55 °C to +150 °C - Full operational range supporting automotive under-hood and industrial ambient environments. |
| Leakage @ VWM | <500 µA - Low reverse leakage preserves signal integrity and minimizes standby power loss in battery-powered systems. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, molded plastic case with matte tin-plated leads; meets UL 94 V-0 flammability rating and JESD 201 Class 2 whisker resistance. Cathode identified by black band on body end.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5A-E3/52 | Commercial-grade version without AEC-Q101 qualification; identical electrical specs and SMB package. | Approved for industrial/commercial use only; not certified for automotive production programs. | Select when AEC-Q101 compliance is not required and cost optimization is prioritized. |
| SMAJ6.5AHE3_A/I | Same electrical parameters but in smaller SMA (DO-214AC) package with lower 400 W PPPM rating. | Lower surge margin limits use to lighter-duty applications like consumer USB ports or low-energy signal lines. | Choose only if board space constraints prohibit SMB footprint and surge threat level is ≤400 W. |
Compared with SMBJ6.5AHE3_A/I, the SMBJ6.5A-E3/52 offers identical protection performance at lower qualification cost, while the SMAJ6.5AHE3_A/I trades 33 % lower surge capacity for 30 % smaller footprint - making the SMBJ6.5AHE3_A/I optimal for automotive and industrial designs demanding full 600 W immunity and AEC-Q101 traceability.

FAQ
What is the clamping voltage of SMBJ6.5AHE3_A/I at its rated peak pulse current?
The SMBJ6.5AHE3_A/I has a maximum clamping voltage (VC) of 11.2 V when subjected to its rated peak pulse current of 53.6 A using the 10/1000 µs waveform. This value is measured under standardized test conditions per JEDEC standards and defines the highest voltage that will appear across the protected line during a full 600 W transient event. The SMBJ6.5AHE3_A/I maintains this clamping performance across its full operating temperature range.
Is SMBJ6.5AHE3_A/I suitable for automotive applications?
Yes, SMBJ6.5AHE3_A/I is AEC-Q101 qualified and specifically designed for automotive use cases including power rail protection in body control modules, infotainment systems, and ADAS sensor interfaces. Its qualification covers temperature cycling, humidity testing, and mechanical shock validation. The "HE3" suffix denotes RoHS-compliant and AEC-Q101 qualified construction, making SMBJ6.5AHE3_A/I appropriate for production automotive programs requiring certified components.
What does the "A/I" suffix mean in SMBJ6.5AHE3_A/I?
The "A/I" suffix in SMBJ6.5AHE3_A/I indicates packaging configuration: "A" refers to the revision code (document revision A), and "I" specifies 13-inch diameter plastic tape-and-reel delivery containing 3200 units per reel. This format supports high-volume automated SMT placement and is compatible with industry-standard pick-and-place equipment. The base part SMBJ6.5AHE3_A/I retains identical electrical and thermal specifications regardless of reel size or revision marking.
How does SMBJ6.5AHE3_A/I compare to bidirectional TVS diodes like SMBJ6.5CA?
The SMBJ6.5AHE3_A/I is unidirectional and intended for DC line protection where polarity is fixed (e.g., +5 V rail to ground), whereas SMBJ6.5CA is bidirectional and suited for AC or differential signal lines. SMBJ6.5AHE3_A/I provides forward conduction capability and lower leakage at VWM, while SMBJ6.5CA clamps symmetrically in both directions with higher VBR tolerance. For single-polarity DC circuits, SMBJ6.5AHE3_A/I delivers superior clamping efficiency and tighter parameter control.
What is the thermal resistance of SMBJ6.5AHE3_A/I from junction to ambient?
The SMBJ6.5AHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on the minimum recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes standard JEDEC test conditions and directly impacts power derating above 25 °C ambient. At 70 °C ambient, the SMBJ6.5AHE3_A/I must be derated to approximately 3.5 W continuous dissipation to maintain safe junction temperature - critical for sustained surge duty cycles in enclosed industrial enclosures.
