Product details
Overview
SMBG160AHE3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) 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, 2.3 A peak pulse current (IPPM) under 10/1000 μs waveform, 259 V clamping voltage (VC) at IPPM, and 600 W peak pulse power rating - deployed in automotive power supply inputs and industrial sensor interfaces.
For engineers reviewing the SMBG160AHE3/52 datasheet, SMBG160AHE3/52 pinout, SMBG160AHE3/52 application, or SMBG160AHE3/52 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 150 °C maximum junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a clamping-type TVS diode, leveraging an avalanche breakdown mechanism to limit transient overvoltages above its VWM threshold. Its glass-passivated junction ensures stable leakage performance and fast response time (<1 ns), while the SMBG package provides MSL Level 1 moisture sensitivity and 260 °C lead-free reflow compatibility.
The SMBG160AHE3/52 is rated for non-repetitive 8.3 ms half-sine surge current up to 100 A (IFSM) and exhibits thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), enabling reliable operation in high-temperature automotive environments when mounted per recommended pad layout.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBG160AE3/52 | Same electrical specs but not AEC-Q101 qualified; industrial grade only | Lacks automotive qualification; unsuitable for under-hood or safety-critical modules | Select SMBG160AHE3/52 when AEC-Q101 compliance is mandatory for OEM automotive programs |
| SMCJ160A | Higher PPPM (1500 W), larger SMC (DO-214AB) package, same VWM/VC | Requires more PCB area; better suited for higher-energy transients where space permits | Choose SMCJ160A only if system-level surge tests exceed 600 W capability and board layout allows larger footprint |
Compared with SMBG160AE3/52, the SMBG160AHE3/52 adds AEC-Q101 qualification without sacrificing electrical performance; versus SMCJ160A, it trades 2.5× lower surge rating for 40 % smaller footprint and full automotive suitability - making it optimal for space-constrained, qualified automotive power nodes.

FAQ
What is the maximum clamping voltage of SMBG160AHE3/52 under standard 10/1000 μs surge conditions?
The SMBG160AHE3/52 has a maximum clamping voltage (VC) of 259 V when subjected to its rated peak pulse current (IPPM) of 2.3 A using the 10/1000 μs waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during transient events. The SMBG160AHE3/52 maintains this clamping performance across its specified operating temperature range.
Is SMBG160AHE3/52 suitable for automotive applications requiring AEC-Q101 qualification?
Yes, SMBG160AHE3/52 is explicitly AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation (Document Number: 88456, Revision: 09-Jan-2024). It undergoes rigorous stress testing including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing. The SMBG160AHE3/52 meets all requirements for use in automotive powertrain, body control, and ADAS subsystems.
What is the thermal resistance specification for SMBG160AHE3/52, and how does it affect PCB layout?
The SMBG160AHE3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead (RθJL) of 20 °C/W, measured on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads. To maintain thermal performance, PCB layout must follow Vishay's recommended pad dimensions and avoid excessive copper isolation. The SMBG160AHE3/52 relies on thermal conduction through its leads and pads - not air convection - for heat dissipation.
Does SMBG160AHE3/52 have bidirectional capability, and how is polarity identified?
No, SMBG160AHE3/52 is a unidirectional TVS diode, indicated by the "A" suffix (vs. "CA" for bidirectional). Polarity is marked by a cathode band on the SMBG package body; the banded end is the cathode and must be connected toward the protected line, while the anode connects to ground. Bidirectional variants like SMBG160CA are functionally distinct and not interchangeable with SMBG160AHE3/52.
What is the peak forward surge current rating for SMBG160AHE3/52, and under what conditions is it specified?
The SMBG160AHE3/52 has a peak forward surge current (IFSM) rating of 100 A, specified for a single 8.3 ms half-sine wave at TA = 25 °C. This rating applies only to unidirectional devices and reflects capability to withstand inrush or fault currents without degradation. The SMBG160AHE3/52 must be used within this limit to ensure long-term reliability - repeated surges above 10% of IFSM require thermal derating per Figure 2 in the datasheet.
