Product details
Overview
SMBG160HE3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the SMBG 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), 600 W peak pulse power (10/1000 µs), <2.3 A maximum reverse leakage at VWM, and clamps to ≤259 V at rated surge current - deployed in automotive power supply inputs and industrial sensor interfaces.
For engineers reviewing the SMBG160HE3/52 datasheet, SMBG160HE3/52 pinout, SMBG160HE3/52 application, or SMBG160HE3/52 equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, DO-215AA package dimensions, clamping performance under 10/1000 µs transients, and direct alternatives with documented VWM/VC/PPPM alignment.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds its specified VBR range (178–197 V at 1 mA). Its low dynamic impedance ensures rapid response (<1 ns) to ESD and lightning-induced surges while maintaining stable clamping up to 600 W peak power.
Designed for surface-mount placement on PCBs with 5.0 mm × 5.0 mm copper pads per terminal, it meets J-STD-020 MSL Level 1 (260 °C reflow peak), supports 100 A IFSM (8.3 ms half-sine), and is qualified to AEC-Q101 for automotive under-hood applications requiring TJ = −55 °C to +150 °C operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 160 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin for 12 V/24 V/48 V systems. |
| VBR (min/max) | 178 V / 197 V at 1 mA - Confirmed breakdown threshold range; ensures predictable turn-on across temperature and unit variation. |
| VC @ IPPM | ≤259 V at 2.3 A (10/1000 µs) - Clamped voltage during full-rated surge; determines protected circuit's maximum stress level. |
| PPPM | 600 W - Peak pulse power handling per 10/1000 µs waveform; enables protection against ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 surges. |
| IR @ VWM | ≤2.3 µA - Reverse leakage at rated stand-off; negligible power loss and no thermal drift in standby conditions. |
| TJ Range | −55 °C to +150 °C - Full automotive-grade junction temperature range; validated for engine control units and battery management systems. |
| AEC-Q101 | Qualified - Certified for automotive use per stress test requirements including HTOL, TCT, and ESD HBM/MM; not just commercial grade. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160AHE3/52 | Same VWM (160 V), identical DO-215AB (SMBJ) package but 10% larger footprint; 600 W rating, slightly higher VC (269 V). | Requires PCB pad revision due to larger body (0.245" × 0.155"); suitable where board real estate permits enhanced thermal mass. | Select if higher surge repetition tolerance is needed; verify pad layout compatibility before drop-in replacement. |
| SMCJ160AHE3/52 | Same VWM and VBR, but SMC (DO-214AB) package with 1500 W rating and higher IPPM; VC = 259 V unchanged. | Occupies significantly larger area (0.285" × 0.235"); used where multi-kW surge immunity is required beyond 600 W. | Choose only when system-level testing confirms need for >600 W capability; not a footprint-compatible substitute. |
Compared with SMBG160HE3/52, SMBJ160AHE3/52 offers identical electrical protection in a physically larger package for improved thermal dissipation, while SMCJ160AHE3/52 delivers triple the pulse power at the cost of 2.5× board area - making SMBG160HE3/52 optimal for space-constrained 600 W applications.

FAQ
What is the clamping voltage of SMBG160HE3/52 under full-rated surge current?
The SMBG160HE3/52 clamps to a maximum of 259 V when subjected to its rated peak pulse current of 2.3 A (10/1000 µs waveform). This value is measured per Figure 1 in Vishay document 88456 and defines the upper voltage limit imposed on protected circuitry during worst-case transients. The SMBG160HE3/52 maintains this clamping performance across its full operating temperature range.
Is SMBG160HE3/52 suitable for automotive applications?
Yes, SMBG160HE3/52 is AEC-Q101 qualified, explicitly stated in the Vishay datasheet revision 12-Nov-12 (document 88456). It undergoes stress testing for high-temperature operating life, temperature cycling, and ESD robustness required for automotive powertrain, body control, and infotainment systems. The "HE3" suffix denotes AEC-Q101 qualification, distinguishing it from commercial-grade "E3" variants.
What does the "HE3" suffix mean in SMBG160HE3/52?
The "HE3" suffix in SMBG160HE3/52 indicates RoHS-compliant construction with AEC-Q101 qualification, per Vishay's ordering nomenclature. "H" designates AEC-Q101 qualification, "E3" denotes RoHS-compliant matte tin plating and JESD201 Class 2 whisker resistance. This is distinct from "E3"-only parts, which are RoHS-compliant but not automotive-qualified.
What is the thermal resistance of SMBG160HE3/52?
The SMBG160HE3/52 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 per terminal, as specified in the Thermal Characteristics table of Vishay document 88456. Its junction-to-lead resistance (RθJL) is 20 °C/W, supporting effective heat transfer to PCB copper during repetitive surge events.
How does SMBG160HE3/52 differ from SMBG160CA?
SMBG160HE3/52 is unidirectional with cathode marking and forward conduction capability, while SMBG160CA is bidirectional (no polarity marking) intended for AC line or differential signal protection. Their VWM and VBR values differ: SMBG160CA has VWM = 160 V but symmetric VBR = ±178–197 V, whereas SMBG160HE3/52 specifies only positive VBR. They are not interchangeable without circuit redesign.
