Product details
Overview
SMBJ160HE3/52 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 a 160 V stand-off voltage (VWM), 178–197 V breakdown voltage (VBR) at 1 mA, 259 V maximum clamping voltage (VC) at 2.3 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in industrial motor drives, telecom power supplies, and automotive body control modules.
For engineers reviewing the SMBJ160HE3/52 datasheet, SMBJ160HE3/52 pinout, SMBJ160HE3/52 application, or SMBJ160HE3/52 equivalent, key selection criteria include clamping performance under 10/1000 µs surge, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), and compatibility with automated SMT assembly on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds its specified VBR range (178–197 V). Its low incremental surge resistance ensures stable clamping during repetitive transients, while the glass-passivated junction delivers fast response time (<1 ns) and high reliability under surge stress.
The device is rated for 150 °C maximum junction temperature and meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow peak. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards, and the HE3 suffix confirms RoHS compliance and AEC-Q101 qualification for automotive-grade deployment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 160 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A-E3/52 | Commercial-grade (non-AEC-Q101), identical electrical specs and SMB package | Lacks automotive qualification; suitable for industrial/commercial power rails only | Select when AEC-Q101 is not required and cost optimization is prioritized |
| SMCJ160AHE3/52 | Same VWM/VBR/VC but in larger SMC (DO-214AB) package; higher RθJA = 40 °C/W, same 600 W rating | Better thermal performance under sustained surge duty; requires larger PCB footprint | Choose when board layout allows larger package and improved thermal margin is critical |
Compared with SMBJ160A-E3/52, the SMBJ160HE3/52 adds AEC-Q101 validation for automotive use without altering clamping behavior; versus SMCJ160AHE3/52, it trades thermal margin for space-constrained designs where SMB footprint is mandatory.

FAQ
What is the clamping voltage of SMBJ160HE3/52 at its rated peak pulse current?
The SMBJ160HE3/52 has a maximum clamping voltage (VC) of 259 V when subjected to its rated peak pulse current (IPPM) of 2.3 A under the standard 10/1000 µs waveform. This value is measured at the device's terminals and defines the upper voltage limit imposed on the protected circuit during transient events. The SMBJ160HE3/52 maintains this clamping performance across its qualified operating temperature range and after multiple surge cycles.
Is SMBJ160HE3/52 suitable for automotive applications?
Yes, SMBJ160HE3/52 is AEC-Q101 qualified, as confirmed by its HE3 suffix and documentation in Vishay's 88392 datasheet. It is validated for automotive use cases including body control modules, infotainment power rails, and sensor interfaces subject to ISO 7637-2 load dump and ISO 16750-2 supply voltage variations. The SMBJ160HE3/52 meets MSL Level 1 and passes whisker testing per JESD 201 Class 2.
How does the SMBJ160HE3/52 differ from the commercial-grade SMBJ160A-E3/52?
The SMBJ160HE3/52 and SMBJ160A-E3/52 share identical electrical characteristics - including VWM = 160 V, VBR = 178–197 V, VC = 259 V, and PPPM = 600 W - but differ in qualification: SMBJ160HE3/52 carries AEC-Q101 certification and is intended for automotive applications, whereas SMBJ160A-E3/52 is commercial-grade only. Both use the same SMB (DO-214AA) package and RoHS-compliant matte tin plating.
What is the thermal resistance of SMBJ160HE3/52, and how does it affect layout design?
The SMBJ160HE3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on the minimum recommended 5.0 mm × 5.0 mm copper pads per terminal. This value directly impacts safe power dissipation: at 50 °C ambient, the device supports up to 5.0 W continuous power (PD) without exceeding 150 °C junction temperature. Layout must replicate the specified pad size and copper area to achieve rated thermal performance.
Can SMBJ160HE3/52 be used in bidirectional configurations?
No, SMBJ160HE3/52 is a unidirectional TVS diode, indicated by its "A" suffix and cathode band marking. Bidirectional operation requires a part with "CA" suffix (e.g., SMBJ160CA). Using SMBJ160HE3/52 in reverse-biased signal paths without proper polarity alignment will result in unintended forward conduction and potential failure. For AC-coupled or differential line protection, select a verified bidirectional variant instead of repurposing the SMBJ160HE3/52.
