Product details
Overview
SMBG6.5AHE3/52 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 6.5 V stand-off voltage (VWM), 7.22–7.98 V breakdown voltage (VBR) at 10 mA, 11.2 V clamping voltage (VC) at 53.6 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed on automotive sensor signal lines, industrial I/O ports, and DC power rails.
For engineers reviewing the SMBG6.5AHE3/52 datasheet, SMBG6.5AHE3/52 pinout, SMBG6.5AHE3/52 application, or SMBG6.5AHE3/52 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 fast-acting shunt clamp during transient events, diverting surge current away from protected circuitry once reverse voltage exceeds VBR. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 μA at 6.5 V), while the low Rsurge enables effective clamping under high-current transients like ESD or inductive switching spikes.
The SMBG6.5AHE3/52 is rated for 100 A non-repetitive forward surge (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-grade reflow assembly and harsh-environment deployment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - maximum continuous reverse working voltage before clamping initiates |
| VBR (min/max) | 7.22 V / 7.98 V at 10 mA - precise breakdown threshold ensuring reliable turn-on margin above VWM |
| VC @ IPPM | 11.2 V at 53.6 A - clamping voltage limiting downstream voltage stress during 600 W surge |
| PPPM | 600 W - peak pulse power handling capability with standardized 10/1000 μs waveform |
| IFSM | 100 A - surge current rating for 8.3 ms half-sine wave, critical for inductive load protection |
| TJ max | +150 °C - extended junction temperature rating enabling use in under-hood automotive environments |
| Leakage @ VWM | <1 μA - minimal standby power loss and signal integrity preservation in high-impedance circuits |
Pinout & Package

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 | Same VWM (6.5 V), but lower PPPM = 600 W (same), higher VC = 11.4 V, SMB (DO-214AA) package | SMB package has larger footprint and higher thermal resistance than SMBG; less suitable for dense automotive layouts | Select SMBG6.5AHE3/52 when AEC-Q101 qualification, MSL Level 1, and compact DO-215AA footprint are required. |
| SMCJ6.5AHE3/52 | Same VWM and AEC-Q101 qualification, but SMC (DO-214AB) package, higher PPPM = 1500 W, VC = 11.2 V | Higher power rating suits heavy-duty industrial surge zones but increases board area and cost | Choose SMBG6.5AHE3/52 where 600 W suffices and space-constrained PCB layout demands SMBG's smaller size. |
Compared with SMBJ6.5A-E3/52 and SMCJ6.5AHE3/52, the SMBG6.5AHE3/52 delivers identical clamping performance in a smaller, automotive-optimized package with verified MSL Level 1 reflow compatibility - making it ideal for space-limited, high-reliability signal-line protection.

FAQ
What is the clamping voltage of SMBG6.5AHE3/52 and how is it measured?
The SMBG6.5AHE3/52 has a maximum clamping voltage (VC) of 11.2 V, measured at its peak pulse current (IPPM) of 53.6 A using a 10/1000 μs standard surge waveform. This value reflects the actual voltage seen by protected circuitry during worst-case transient events and is guaranteed per Vishay's datasheet test conditions with specified mounting pad layout.
Is SMBG6.5AHE3/52 suitable for automotive applications?
Yes, SMBG6.5AHE3/52 is AEC-Q101 qualified and manufactured with HE3 suffix indicating RoHS compliance and automotive-grade reliability. Its -55 °C to +150 °C operating range, MSL Level 1 reflow rating, and validated surge performance make it appropriate for engine control units, ADAS camera modules, and body electronics where transient immunity is critical.
What does the "HE3/52" suffix mean in SMBG6.5AHE3/52?
The "HE3" suffix denotes RoHS-compliant, AEC-Q101-qualified construction with matte tin-plated leads meeting J-STD-002 solderability standards; "/52" specifies packaging in 7" diameter plastic tape and reel with 750 units per reel - optimized for high-speed SMT placement equipment used in automotive and industrial manufacturing.
How does SMBG6.5AHE3/52 differ from bidirectional TVS diodes like SMBG6.5CA?
SMBG6.5AHE3/52 is unidirectional and intended for DC-biased lines where polarity is fixed (e.g., VCC to ground); SMBG6.5CA is bidirectional and suited for AC or floating signal lines like data buses. The unidirectional SMBG6.5AHE3/52 offers lower leakage and sharper turn-on but requires correct polarity orientation during placement.
What is the thermal resistance of SMBG6.5AHE3/52 and why does it matter?
SMBG6.5AHE3/52 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. This value determines how effectively heat from surge dissipation transfers to the PCB - critical for sustaining repeated transient events without exceeding the 150 °C max junction temperature limit.
