Product details
Overview
SMBJ60HE3/52 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 DC power rails and signal lines. It features 60 V stand-off voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 96.8 V maximum clamping voltage (VC) at 6.2 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive ECUs, industrial I/O modules, and telecom power supplies.
For engineers reviewing the SMBJ60HE3/52 datasheet, SMBJ60HE3/52 pinout, SMBJ60HE3/52 application, or SMBJ60HE3/52 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (−55 to +150 °C), and RoHS-compliant packaging details essential for ESD/surge protection design-in and BOM validation.
Technical Context
This TVS diode operates as a unidirectional clamping device: reverse-biased during normal operation (blocking up to 60 V), then rapidly avalanching into low-impedance conduction when transients exceed VBR. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 µA at VWM), while the SMB package supports automated SMT placement and meets MSL Level 1 per J-STD-020.
Designed for single-pulse surge suppression per IEC 61000-4-5 (10/1000 µs), it delivers 6.2 A peak pulse current (IPPM) with 96.8 V clamping, enabling reliable protection of downstream MOSFETs, ICs, and sensors against inductive switching spikes and lightning-induced surges in 12–48 V systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| VWM | 60 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin for 48 V nominal systems. |
| VBR (min/max) | 66.7 V / 73.7 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on without premature conduction. |
| VC @ IPPM | 96.8 V at 6.2 A - Clamped voltage during 10/1000 µs surge; determines maximum stress on protected ICs. |
| PPPM | 600 W - Peak pulse power handling capability; validates compliance with IEC 61000-4-5 Level 3/4 surge tests. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; informs derating above 25 °C ambient. |

FAQ
What is the clamping voltage of SMBJ60HE3/52 at its rated peak pulse current?
The SMBJ60HE3/52 has a maximum clamping voltage (VC) of 96.8 V at its rated peak pulse current (IPPM) of 6.2 A, measured using the standardized 10/1000 µs double-exponential surge waveform. This value defines the upper voltage limit imposed on protected circuitry during a worst-case transient event and is confirmed in the Vishay datasheet Document Number 88392, page 2.
Is SMBJ60HE3/52 qualified for automotive applications?
Yes, SMBJ60HE3/52 is AEC-Q101 qualified, as indicated by the "HE3" suffix in its part number. This certification covers stress tests including high-temperature reverse bias, temperature cycling, and ESD, validating its suitability for under-hood and chassis-mounted automotive electronics such as body control modules and ADAS sensor interfaces.
What does the "/52" suffix indicate in SMBJ60HE3/52?
The "/52" suffix in SMBJ60HE3/52 denotes the preferred packaging configuration: 750 units per 7-inch diameter plastic tape-and-reel. This format is optimized for high-speed SMT placement equipment and aligns with industry-standard reel dimensions and orientation requirements for automated manufacturing.
How does SMBJ60HE3/52 differ from SMBJ60A-E3/52?
SMBJ60HE3/52 and SMBJ60A-E3/52 share identical electrical specifications and SMB (DO-214AA) package dimensions, but SMBJ60HE3/52 carries AEC-Q101 qualification while SMBJ60A-E3/52 is commercial-grade only. Both are RoHS-compliant, but only the HE3 variant is approved for automotive production use per Vishay's ordering information table.
What is the maximum operating junction temperature for SMBJ60HE3/52?
The SMBJ60HE3/52 has a maximum operating junction temperature (TJ) of +150 °C, as specified in the Vishay datasheet. This rating allows reliable operation in high-ambient environments such as engine compartments or enclosed industrial enclosures, provided thermal design accounts for its RθJA of 100 °C/W on standard copper pads.
