Product details
Overview
SMBG6.5HE3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-215AA (SMBG) package, designed for robust overvoltage protection of DC power rails 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 clamping voltage (VC) at 53.6 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used in automotive power supply input stages and industrial sensor interface protection.
For engineers reviewing the SMBG6.5HE3/52 datasheet, SMBG6.5HE3/52 pinout, SMBG6.5HE3/52 application, or SMBG6.5HE3/52 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 150 °C max junction temperature, RoHS-compliant matte tin plating, and compliance with UL 497B for telecom/sensor surge protection.
Technical Context
This TVS diode operates as a clamping device that remains high-impedance below VWM = 6.5 V and rapidly transitions to low-impedance conduction above VBR (min 7.22 V), limiting transient voltages to ≤11.2 V at 53.6 A. Its glass-passivated junction ensures stable leakage (<500 µA at VWM) and fast response time (<1 ns).
Designed for mounting on 5.0 mm × 5.0 mm copper pads per terminal, it delivers 600 W peak pulse power under 10/1000 µs waveform with 0.01% duty cycle, and supports repetitive surge events while maintaining thermal resistance RθJA = 100 °C/W and RθJL = 20 °C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 7.22 V / 7.98 V at 10 mA - guaranteed breakdown range defining turn-on threshold |
| VC @ IPPM | 11.2 V at 53.6 A - clamped voltage during 600 W transient, critical for downstream IC survival |
| IPPM | 53.6 A - peak surge current capability under 10/1000 µs waveform |
| PPPM | 600 W - peak pulse power handling capacity, derated above 25 °C ambient |
| TJ max | +150 °C - maximum junction temperature enabling operation in under-hood automotive environments |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5A-E3/52 | Same VWM/VBR/VC, but rated for 600 W with larger SMB (DO-214AA) package; RθJA = 85 °C/W vs. 100 °C/W | Higher thermal mass suits higher average surge duty cycles; less space-efficient than SMBG | Select SMBJ6.5A-E3/52 when board layout allows larger footprint and thermal performance is prioritized over density |
| SMCJ6.5AHE3/52 | Same electrical specs but in SMC (DO-214AB) package; 1500 W PPPM, 113 A IPPM, RθJA = 50 °C/W | Higher surge capacity for severe environments (e.g., railway traction control); not AEC-Q101 qualified | Choose SMCJ6.5AHE3/52 only if 1500 W rating is required and automotive qualification is not mandatory |
Compared with SMBG6.5HE3/52, SMBJ6.5A-E3/52 offers better thermal dissipation in a slightly larger footprint, while SMCJ6.5AHE3/52 provides triple the surge power but lacks AEC-Q101 validation - making SMBG6.5HE3/52 optimal for space-constrained, automotive-qualified designs requiring precise 600 W clamping.

FAQ
What is the clamping voltage of SMBG6.5HE3/52 and how is it measured?
The SMBG6.5HE3/52 has a maximum clamping voltage (VC) of 11.2 V, measured at its peak pulse current (IPPM) of 53.6 A using a standardized 10/1000 µs double-exponential surge waveform. This value is guaranteed across the full operating temperature range and reflects the actual voltage seen by protected circuitry during worst-case transient events - critical for ensuring downstream components remain within absolute maximum ratings.
Is SMBG6.5HE3/52 suitable for automotive applications?
Yes, SMBG6.5HE3/52 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its 150 °C maximum junction temperature, MSL Level 1 reflow compatibility, and JESD 201 Class 2 whisker resistance make it appropriate for engine control modules, body control units, and ADAS sensor interfaces where reliability under thermal and mechanical stress is mandatory.
How does the HE3 suffix differ from E3 in SMBG6.5HE3/52?
The HE3 suffix in SMBG6.5HE3/52 indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas E3 denotes RoHS compliance only (commercial grade). The HE3 version undergoes additional stress testing including temperature cycling, highly accelerated life testing (HALT), and failure analysis - confirming suitability for mission-critical automotive deployments where SMBG6.5HE3/52 is specified.
What is the reverse leakage current of SMBG6.5HE3/52 at rated stand-off voltage?
At its rated stand-off voltage (VWM) of 6.5 V and ambient temperature of 25 °C, the SMBG6.5HE3/52 exhibits a maximum reverse leakage current (ID) of 500 µA. This low leakage ensures minimal power loss in always-on circuits and prevents false triggering in high-impedance sensor bias networks - a key design advantage confirmed in Vishay's Electrical Characteristics table for uni-directional SMBG devices.
Can SMBG6.5HE3/52 be used in bi-directional configurations?
No, SMBG6.5HE3/52 is a unidirectional TVS diode, as indicated by its "A" suffix and cathode band marking. Bi-directional variants in the same family carry the "CA" suffix (e.g., SMBG6.5CA). Using SMBG6.5HE3/52 in bi-directional applications would leave positive-going transients unprotected; for symmetric surge suppression, select SMBG6.5CAHE3/52 instead - which has identical packaging and AEC-Q101 qualification but dual-clamp architecture.
