Product details
Overview
SMBJ160AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in the 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, and 600 W peak pulse power rating with 10/1000 µs waveform.
For engineers reviewing the SMBJ160AHE3_A/H datasheet, SMBJ160AHE3_A/H pinout, SMBJ160AHE3_A/H application, or SMBJ160AHE3_A/H equivalent, this device is selected for high-reliability industrial power supply input protection, automotive body control module (BCM) interface surge suppression, and telecom line card transient immunity where AEC-Q101 qualification, low clamping ratio, and stable thermal performance up to +150 °C junction temperature are required.
Technical Context
This TVS diode operates as a unidirectional clamping device: under normal bias it presents high impedance (>1 µA leakage at 160 V), but triggers into low-impedance conduction when reverse voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5%) and fast response time (<1 ns), enabling effective suppression of ESD, lightning-induced surges, and inductive switching transients.
The SMBJ160AHE3_A/H is rated for 100 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine), exhibits a 0.108 %/°C temperature coefficient of VBR, and achieves thermal resistance of 100 °C/W (junction-to-ambient) on standard 0.2" × 0.2" copper pads - confirming suitability for compact PCB layouts without active cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 160 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC rail protection level. |
| VBR (min/max) | 178 V / 197 V at IT = 1 mA - Confirmed breakdown range ensuring reliable triggering margin above VWM. |
| VC @ IPPM | 259 V at 2.3 A - Clamping voltage during 10/1000 µs surge; limits downstream IC stress to ≤259 V. |
| PPPM | 600 W - Peak pulse power handling capability; supports IEC 61000-4-5 Level 4 (4 kV) surge testing. |

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), same VWM/VBR/VC, identical SMB package and pinout. | Approved for industrial/commercial use only; not validated for automotive temperature cycling or humidity testing. | Select when cost sensitivity outweighs automotive qualification requirements and ambient temperature remains <125 °C. |
| SMCJ160AHE3_A/H | Same electrical specs but in larger SMC (DO-214AB) package; 1500 W PPPM rating; RθJA = 40 °C/W. | Higher power handling and lower thermal resistance enable use in high-energy surge zones (e.g., AC front-end). | Choose when system-level surge tests exceed 600 W or board layout permits larger footprint for improved thermal margin. |
Compared with SMBJ160A-E3/52, the SMBJ160AHE3_A/H adds AEC-Q101 qualification for automotive deployment, while versus SMCJ160AHE3_A/H it trades 900 W extra pulse power for 40% smaller PCB area and tighter placement flexibility near sensitive nodes.

FAQ
What is the maximum clamping voltage of SMBJ160AHE3_A/H at its rated peak pulse current?
The SMBJ160AHE3_A/H has a maximum clamping voltage (VC) of 259 V at its specified peak pulse current (IPPM) of 2.3 A using the 10/1000 µs waveform. This value is measured under standardized test conditions per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBJ160AHE3_A/H maintains this clamping performance across its full operating temperature range.
Is SMBJ160AHE3_A/H suitable for automotive applications?
Yes, SMBJ160AHE3_A/H is AEC-Q101 qualified, meaning it has passed rigorous stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing - specifically validating its use in automotive subsystems such as body control modules, lighting drivers, and infotainment power rails. The "HE3" suffix explicitly denotes this qualification, distinguishing it from commercial-grade variants like SMBJ160A-E3/52.
What does the "A" suffix indicate in SMBJ160AHE3_A/H?
The "A" in SMBJ160AHE3_A/H denotes unidirectional polarity - confirming that the device functions as a single-ended TVS diode with cathode band marking, intended for DC rail protection where surge direction is known and controlled. This contrasts with "CA" suffix parts (e.g., SMBJ160CA), which are bidirectional and used in AC-coupled or differential signal paths where polarity reversal may occur.
How does SMBJ160AHE3_A/H compare to SMAJ160AHE3_A/H in terms of power handling?
SMBJ160AHE3_A/H delivers 600 W peak pulse power (10/1000 µs), whereas SMAJ160AHE3_A/H is rated for only 400 W in the smaller SMA (DO-214AC) package. The SMB outline provides greater thermal mass and lower thermal resistance (RθJA = 100 °C/W vs. ~130 °C/W for SMAJ), making SMBJ160AHE3_A/H more robust for repeated surge exposure in high-reliability applications like industrial controls or automotive ECUs.
What is the reverse leakage current specification for SMBJ160AHE3_A/H at its stand-off voltage?
At the rated stand-off voltage (VWM) of 160 V and ambient temperature of 25 °C, the SMBJ160AHE3_A/H exhibits a maximum reverse leakage current (ID) of 1.0 µA. This low leakage ensures minimal power loss and no measurable loading on the protected 160 V DC rail during normal operation, preserving efficiency and stability in always-on systems such as telecom power supplies or automotive always-live circuits.
