Product details
Overview
SMA6J17AH from Taiwan Semiconductor is a 600W surface-mount transient voltage suppressor (TVS) diode with a working stand-off voltage of 17 V, breakdown voltage range 18.9–20.9 V, and clamping voltage of 26.7 V at 1.0 A peak pulse current. It features AEC-Q101 qualification, DO-214AC (SMA) package, and is designed for automotive-grade surge protection in DC/DC converters and power supplies.
For engineers reviewing the SMA6J17AH datasheet, SMA6J17AH pinout, SMA6J17AH application, or SMA6J17AH equivalent, key selection criteria include its 17 V VWM, 26.7 V VC @ 1.0 A, AEC-Q101 qualification, ISO 7637-2 compliance, and DO-214AC mechanical footprint-critical for automotive ECU, infotainment, and body control module designs requiring robust transient immunity.
Technical Context
The SMA6J17AH is a unidirectional, single-die TVS diode optimized for fast clamping of high-energy transients using a glass-passivated junction. Its 10/1000 μs waveform rating delivers 600 W peak pulse power with sub-1 ps response time and clamps to ≤26.7 V at 1.0 A IPPM.
It operates across –55 °C to +175 °C junction temperature, supports 50 A non-repetitive forward surge current (8.3 ms half-sine), and meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity requirements-enabling use in reflow-soldered automotive modules.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ17A | VWM = 17 V, VC = 27.6 V @ 1.0 A, PPPM = 400 W, AEC-Q101 qualified | Lower peak power rating reduces margin against severe ISO 7637-2 Pulse 1 events | Acceptable where system-level testing confirms 400 W suffices; verify clamping margin with actual surge profile |
| ON Semiconductor SMA6J17A | VWM = 17 V, VC = 27.1 V @ 1.0 A, PPPM = 600 W, AEC-Q101 qualified, same DO-214AC package | Identical electrical specs and qualification; minor VC variation (27.1 V vs. 26.7 V) within tolerance band | Drop-in alternative with identical board fit and functional performance; suitable for dual-sourcing programs |
Compared with SMAJ17A, the SMA6J17AH offers 50% higher peak pulse power (600 W vs. 400 W), improving surge margin in harsh automotive environments; versus SMA6J17A, it provides tighter clamping (26.7 V vs. 27.1 V) and identical AEC-Q101/ISO 7637-2 compliance-making it preferred for next-gen BCM and ADAS power domains.

FAQ
What is the clamping voltage of the SMA6J17AH under a 10/1000 μs surge?
The SMA6J17AH has a maximum clamping voltage (VC) of 26.7 V when subjected to a 1.0 A peak pulse current with a 10/1000 μs waveform. This value is measured per standard test conditions and ensures downstream components remain below their absolute maximum voltage ratings during transient events. The SMA6J17AH maintains this clamping performance across its specified operating temperature range.
Is the SMA6J17AH qualified for automotive applications?
Yes, the SMA6J17AH is AEC-Q101 qualified and meets ISO 7637-2 requirements for Pulses 1, 2a, 2b, 3a, and 3b. It is rated for junction temperatures from –55 °C to +175 °C and complies with JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity-making it suitable for under-hood and chassis-mounted automotive electronics.
What package does the SMA6J17AH use, and is it compatible with standard SMT processes?
The SMA6J17AH uses the DO-214AC (SMA) surface-mount package with matte tin-plated leads that are solderable per J-STD-002. Its Level 1 moisture sensitivity rating means no dry-pack or baking is required prior to reflow. The low-profile design supports automated placement and is compatible with standard lead-free reflow profiles.
How does the SMA6J17AH compare to the SMA6J17A from ON Semiconductor?
The SMA6J17AH and ON Semiconductor's SMA6J17A share identical VWM (17 V), PPPM (600 W), DO-214AC package, and AEC-Q101 qualification. The SMA6J17AH specifies VC = 26.7 V @ 1.0 A, while SMA6J17A specifies 27.1 V-within typical process variation. Both are functionally interchangeable in most automotive designs requiring unidirectional TVS protection.
What is the maximum steady-state power dissipation for the SMA6J17AH?
The SMA6J17AH has a steady-state power dissipation (PD) rating of 4 W at TA = 25 °C. This value applies only to continuous DC or low-frequency operation-not transient suppression. For surge events, the device relies on its 600 W peak pulse power rating (10/1000 μs), and thermal design must account for junction-to-ambient resistance and PCB copper area to maintain TJ ≤ 175 °C.
