Product details
Overview
SMBJ6.0HE3/52 from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for robust overvoltage protection of sensitive electronics. 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), clamping voltage of 10.3 V at 58.3 A, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMBJ6.0HE3/52 datasheet, SMBJ6.0HE3/52 pinout, SMBJ6.0HE3/52 application, or SMBJ6.0HE3/52 equivalent, key selection considerations include its unidirectional polarity, 10.3 V clamping performance under 58.3 A surge, AEC-Q101 qualification status, RoHS-compliant matte tin terminals, and compatibility with automated SMT placement on standard PCB pads.
Technical Context
This TVS diode operates as a clamping device that remains non-conductive below 6.0 V and rapidly transitions to low-impedance conduction above its breakdown threshold to divert transient energy away from protected circuitry. Its glass-passivated junction ensures stable leakage (<800 µA at VWM) and repeatable clamping behavior across temperature.
The SMBJ6.0HE3/52 delivers 600 W peak pulse power handling with a 10/1000 µs waveform, exhibits 0.059 %/°C VBR temperature coefficient, and maintains operation from –55 °C to +150 °C junction temperature - enabling reliable protection in automotive engine control units, industrial motor drives, and telecom interface circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before significant leakage begins; defines safe signal line operating margin. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Confirmed breakdown range ensuring predictable turn-on during transients without premature conduction. |
| VC @ IPPM | 10.3 V at 58.3 A - Clamped voltage during full 600 W surge; determines maximum stress imposed on downstream ICs or MOSFETs. |
| IPPM | 58.3 A - Peak surge current capability with 10/1000 µs waveform; validates protection against IEC 61000-4-5 Level 4 surges. |
| PPPM | 600 W - Peak pulse power rating; enables single-device suppression of high-energy transients induced by inductive switching or ESD. |
| TJ max. | +150 °C - Maximum junction temperature; supports operation in under-hood automotive environments and enclosed industrial enclosures. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; polarity indicated by cathode band.
| Pin/Terminal | Circuit Role | Design Meaning |

Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Enables single-device suppression of high-energy transients from relay coil flyback or lightning-induced surges without derating. |
| AEC-Q101 qualified | Validated for automotive applications including engine control modules, body electronics, and ADAS sensor interfaces. |
| Glass passivated junction | Ensures stable VBR, low leakage (<800 µA), and long-term reliability under thermal cycling and humidity exposure. |
| MSL Level 1 (260 °C peak reflow) | Supports standard lead-free SMT reflow profiles without moisture-related popcorning or delamination. |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (e.g., ESD), improving protection margin for 3.3 V/5 V logic. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0A-E3/52 | Commercial-grade version; same VWM, VBR, VC, and PPPM, but not AEC-Q101 qualified. | Lacks automotive qualification; suitable for consumer or industrial applications where extended temperature validation is not required. | Select SMBJ6.0A-E3/52 for cost-sensitive non-automotive designs with identical electrical specs. |
| SMAJ6.0AHE3/A | Lower 400 W PPPM; SMA package (smaller footprint); higher RθJA (140 °C/W vs. 100 °C/W). | Reduced surge handling; limited to lower-energy transients; less thermal margin in high-power density layouts. | Choose SMAJ6.0AHE3/A only when board space is constrained and peak surge currents remain below 36.7 A. |
Compared with SMBJ6.0A-E3/52, the SMBJ6.0HE3/52 adds AEC-Q101 qualification for automotive use without sacrificing electrical performance; versus SMAJ6.0AHE3/A, it provides 50 % higher surge power handling and superior thermal dissipation in the larger SMB package.

FAQ
What is the clamping voltage of SMBJ6.0HE3/52 and how is it measured?
The SMBJ6.0HE3/52 has a maximum clamping voltage (VC) of 10.3 V, measured at its peak pulse current (IPPM) of 58.3 A using a 10/1000 µs waveform. This value represents the actual voltage seen across the device during a full 600 W transient event and is critical for determining whether downstream components remain within their absolute maximum ratings.
Is SMBJ6.0HE3/52 suitable for automotive applications?
Yes, SMBJ6.0HE3/52 is AEC-Q101 qualified and specifically designed for automotive use. Its construction includes glass-passivated junctions, MSL Level 1 reflow compatibility, and validated performance across –55 °C to +150 °C, making it appropriate for engine control units, body control modules, and ADAS sensor interfaces.
How does the SMBJ6.0HE3/52 differ from the SMBJ6.0A-E3/52?
The SMBJ6.0HE3/52 and SMBJ6.0A-E3/52 share identical electrical specifications - including VWM = 6.0 V, VBR = 6.67–7.37 V, and VC = 10.3 V - but differ in qualification: SMBJ6.0HE3/52 is AEC-Q101 qualified, whereas SMBJ6.0A-E3/52 is commercial grade only. Both use RoHS-compliant matte tin terminations and SMB (DO-214AA) packaging.
What is the maximum reverse leakage current for SMBJ6.0HE3/52 at rated VWM?
The SMBJ6.0HE3/52 exhibits a maximum reverse leakage current (ID) of 800 µA at its rated stand-off voltage of 6.0 V and ambient temperature of 25 °C. This low leakage ensures minimal power loss and signal distortion in always-on protection circuits such as automotive CAN bus or sensor bias rails.
Can SMBJ6.0HE3/52 be used in bidirectional configurations?
No, SMBJ6.0HE3/52 is a unidirectional TVS diode, identifiable by its cathode band marking. For bidirectional protection, Vishay offers the SMBJ6.0CA variant (e.g., SMBJ6.0CAHE3/52), which provides symmetrical clamping in both polarities and is designated with a "CA" suffix instead of "A".
