Product details
Overview
SMAJ60AHE3_A/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection on power and signal lines. It features a 60 V standoff voltage (VWM), 66.7–73.7 V breakdown range at 1 mA, 96.8 V maximum clamping voltage at 4.1 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform-used to safeguard MOSFETs, ICs, and sensor interfaces in automotive power systems.
For engineers reviewing the SMAJ60AHE3_A/I datasheet, SMAJ60AHE3_A/I pinout, SMAJ60AHE3_A/I application, or SMAJ60AHE3_A/I equivalent, key selection criteria include unidirectional polarity, SMA (DO-214AC) package compatibility, AEC-Q101 qualification status, and clamping performance under repetitive surge conditions in 12 V/24 V vehicle subsystems.
Technical Context
This TVS diode operates as a shunt-clamping device that remains high-impedance below VWM = 60 V and rapidly transitions to low-impedance conduction above its VBR threshold (66.7–73.7 V). Its glass-passivated junction ensures stable avalanche behavior, while thermal resistance RθJA = 120 °C/W and RθJL = 30 °C/W support reliable operation up to TJ = 150 °C.
Designed for automotive-grade reliability, SMAJ60AHE3_A/I meets AEC-Q101 stress testing requirements and is RoHS-compliant with matte tin-plated leads solderable per J-STD-002. The "HE3" suffix denotes AEC-Q101 qualification and RoHS compliance; "_A/I" indicates 7500-unit tape-and-reel packaging on 13″ reels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60A-E3/61 | Same electrical specs; RoHS-compliant but not AEC-Q101 qualified; packaged in 1800-unit 7″ reel. | Intended for commercial/industrial use where automotive qualification is not required. | Select when cost sensitivity outweighs automotive reliability requirements and smaller reel size is preferred. |
| SMCJ60AHE3_A/I | Higher 1500 W PPPM, same VWM/VC; larger SMC (DO-214AB) package with 7.11 mm × 6.22 mm footprint. | Used where higher surge margin is needed (e.g., alternator output lines), accepting larger board area. | Choose when system-level surge testing exceeds 400 W requirements and PCB layout allows SMC footprint. |
Compared with SMAJ60A-E3/61, SMAJ60AHE3_A/I adds AEC-Q101 validation and larger reel quantity; versus SMCJ60AHE3_A/I, it trades surge capacity for compact SMA footprint-making SMAJ60AHE3_A/I optimal for space-constrained automotive modules needing certified reliability.

FAQ
What is the clamping voltage of SMAJ60AHE3_A/I at its rated peak pulse current?
The SMAJ60AHE3_A/I has a maximum clamping voltage (VC) of 96.8 V at its specified peak pulse current (IPPM) of 4.1 A, measured using the standardized 10/1000 μs double-exponential surge waveform. This value is guaranteed per Vishay's datasheet revision 09-Jan-2024 and defines the upper voltage limit imposed on protected circuitry during transient events. The SMAJ60AHE3_A/I maintains this clamping performance across its full operating temperature range.
Is SMAJ60AHE3_A/I suitable for protecting CAN bus lines?
No-SMAJ60AHE3_A/I is not recommended for direct CAN bus line protection because its 60 V standoff voltage exceeds the typical ±15 V common-mode range of high-speed CAN transceivers. Using SMAJ60AHE3_A/I on CAN_H/CAN_L would risk false triggering or insufficient protection margin. For CAN-specific protection, lower-voltage TVS arrays like SM712 or specialized bidirectional CAN protectors are appropriate. SMAJ60AHE3_A/I is intended for 12 V/24 V power rail and high-side signal protection.
Does SMAJ60AHE3_A/I have bidirectional capability?
No-SMAJ60AHE3_A/I is a unidirectional TVS diode, as indicated by the "A" suffix (versus "CA" for bidirectional variants). It conducts only when the cathode is positive relative to the anode, making it suitable for DC power line protection where polarity is fixed. Bidirectional operation requires parts like SMAJ60CAHE3_A/I, which clamp symmetrically for AC or floating signal lines.
What does the "HE3" suffix mean in SMAJ60AHE3_A/I?
The "HE3" suffix in SMAJ60AHE3_A/I denotes RoHS-compliant construction with AEC-Q101 qualification-confirming the device has passed accelerated stress tests for automotive use, including temperature cycling, humidity bias, and high-temperature operating life. This distinguishes it from commercial-grade "E3" variants and ensures suitability for under-hood and safety-critical vehicle subsystems. The SMAJ60AHE3_A/I part number explicitly identifies this qualified version.
Can SMAJ60AHE3_A/I be used in parallel to increase surge current handling?
Parallel connection of SMAJ60AHE3_A/I devices is not recommended due to mismatch in dynamic impedance and breakdown voltage tolerance (±10 %), which causes uneven current sharing and potential thermal runaway. For higher surge ratings, select a single higher-power device such as SMCJ60AHE3_A/I (1500 W) or SMAJ60AHE3_A/I with external current-sharing resistors-though the latter degrades clamping performance. Always validate parallel configurations with empirical surge testing.
