Product details
Overview
SMA6J13AH from Taiwan Semiconductor is a 600W surface-mount transient voltage suppressor (TVS) diode with a 14.4V minimum breakdown voltage, 15.9V maximum breakdown voltage, and 20.4V clamping voltage at 1A peak pulse current; designed for automotive-grade overvoltage protection in DC/DC converters and power adapters.
For engineers reviewing the SMA6J13AH datasheet, SMA6J13AH pinout, SMA6J13AH application, or SMA6J13AH equivalent, key selection criteria include its AEC-Q101 qualification, DO-214AC (SMA) package, 1.0µA max reverse leakage at 13V working stand-off, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, and 175°C junction temperature rating.
Technical Context
This unidirectional TVS diode uses a glass-passivated junction to achieve fast response time (<1.0ps) and stable clamping performance under repetitive transients. Its single-die configuration in DO-214AC supports automated placement and meets JESD201 Class 2 whisker resistance.
The device operates across –55°C to +175°C junction temperature range and delivers 600W peak pulse power (10/1000μs waveform) with 29.4A maximum peak impulse current. It exhibits 1.0µA max reverse leakage at VWM = 13V and maintains clamping voltage ≤20.4V at rated IPPM.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J13A (ON Semiconductor) | Same DO-214AC package; VBR = 14.4–15.9V, VC = 20.4V @ 1A, but not AEC-Q101 qualified | Lacks automotive qualification; suitable only for commercial/industrial environments | Select SMA6J13AH when AEC-Q101 compliance is mandatory for vehicle subsystems |
| 1.5SMC13AH (Littelfuse) | Same VWM/VBR/VC specs; 600W rating; DO-214AB (SMB) package - 1.6mm wider than SMA | Requires PCB pad revision due to larger footprint and different thermal mass | Choose SMA6J13AH for space-constrained layouts where DO-214AC's 4.5mm × 2.7mm outline is critical |
Compared with SMA6J13A and 1.5SMC13AH, SMA6J13AH uniquely combines AEC-Q101 qualification, DO-214AC footprint, and verified ISO 7637-2 immunity-making it the preferred choice for automotive power rail protection where qualification, size, and standard compliance are jointly required.

FAQ
What is the maximum clamping voltage of SMA6J13AH at its rated peak pulse current?
The SMA6J13AH has a maximum clamping voltage (VC) of 20.4V at 1A peak pulse current (IPPM) under the standardized 10/1000μs waveform. This value is measured per the device's electrical specifications table and ensures protected circuits remain below critical voltage thresholds during surge events. The SMA6J13AH maintains this clamping performance across its full operating temperature range.
Is SMA6J13AH qualified for automotive applications?
Yes, SMA6J13AH is AEC-Q101 qualified and explicitly tested to meet ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b requirements. Its construction-including glass-passivated junction, DO-214AC package with JESD201 Class 2 whisker resistance, and moisture sensitivity level 1-supports deployment in engine control units, body electronics, and ADAS power domains where reliability under thermal and mechanical stress is mandatory.
What is the working stand-off voltage (VWM) of SMA6J13AH, and why does it matter?
The SMA6J13AH has a working stand-off voltage (VWM) of 13V, meaning it remains in high-impedance state with ≤1.0µA reverse leakage up to this DC or RMS voltage. This parameter ensures no functional interference with nominal 12V automotive or industrial rails while guaranteeing rapid avalanche conduction when transients exceed VBR. Selecting a VWM ≥110% of system nominal voltage prevents false triggering.
Does SMA6J13AH require special PCB layout considerations?
Yes-SMA6J13AH should be placed as close as possible to the protected node (e.g., IC power pin or connector) with minimal trace length to reduce inductance. Its DO-214AC (SMA) package requires the recommended pad layout from TSC's datasheet (Version A2102, Page 5), including thermal relief for soldering and clearance from adjacent copper. Avoid routing high-dI/dt traces near its cathode-anode path to prevent coupling.
What is the peak pulse power rating of SMA6J13AH, and under what test condition is it specified?
The SMA6J13AH is rated for 600W peak pulse power (PPPM) under the non-repetitive 10/1000μs double-exponential waveform defined by R.E.A. and referenced in IEC 61000-4-5. This rating reflects the device's ability to absorb transient energy without failure, provided the pulse repetition rate remains low enough to allow junction temperature recovery between events-as confirmed in the Pulse Derating Curve (Fig.2) of the datasheet.
