Product details
Overview
SMA6J16AH from Taiwan Semiconductor is a 600W surface-mount transient voltage suppressor (TVS) diode with a 16V working stand-off voltage, 17.8–19.7V breakdown range at 1mA, and 25.2V maximum clamping voltage at 23.8A peak pulse current. It features AEC-Q101 qualification, DO-214AC (SMA) package, and is designed for automotive-grade DC/DC converter protection against ISO 7637-2 transients.
For engineers reviewing the SMA6J16AH datasheet, SMA6J16AH pinout, SMA6J16AH application, or SMA6J16AH equivalent, key selection criteria include clamping performance under 10/1000μs surge, junction temperature rating up to +175°C, compliance with automotive pulse immunity standards, and lead-free, halogen-free construction per J-STD-020 Level 1 and IEC 61249-2-21.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction to achieve sub-1ps response time and stable clamping across repeated transients. Its single-die DO-214AC configuration supports automated SMT placement and delivers 600W peak pulse power handling with <1.0μA reverse leakage at 16V.
The device operates over –55°C to +175°C junction temperature and meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b test requirements-making it suitable for harsh automotive environments where load dump and inductive switching surges occur on 12V/24V supply rails.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J16A (ON Semiconductor) | Same DO-214AC package, identical VWM/VBR/VC specs, but not AEC-Q101 qualified | Lacks automotive qualification; unsuitable for OEM vehicle ECUs requiring AEC compliance | Select SMA6J16AH when AEC-Q101 validation is mandatory for production release |
| SMC6J16A (Littelfuse) | Higher package thermal mass (DO-214AB), 600W rating, same electrical specs, AEC-Q101 qualified | Requires PCB pad redesign due to larger SMC footprint; better thermal dissipation for high-duty-cycle surges | Choose SMC6J16A only if board layout allows larger package and enhanced steady-state power handling is needed |
Compared with SMA6J16A and SMC6J16A, the SMA6J16AH uniquely combines AEC-Q101 qualification, DO-214AC form factor, and verified 25.2V clamping at 23.8A-making it the optimal choice for space-constrained automotive modules needing certified surge robustness without footprint change.

FAQ
What is the maximum clamping voltage of the SMA6J16AH under a 10/1000μs surge?
The SMA6J16AH has a maximum clamping voltage (VC) of 25.2 V when subjected to its rated peak pulse current of 23.8 A under the standardized 10/1000μs waveform. This value is measured and guaranteed per the manufacturer's electrical specifications table and ensures protected downstream components remain within safe voltage limits during transient events.
Is the SMA6J16AH suitable for automotive applications requiring AEC-Q101 qualification?
Yes, the SMA6J16AH is explicitly AEC-Q101 qualified as stated in its official datasheet features list. This certification validates its reliability for use in automotive electronic control units, including body control modules and powertrain subsystems, where extended temperature operation and mechanical stress resistance are required.
What is the working stand-off voltage (VWM) of the SMA6J16AH?
The SMA6J16AH has a working stand-off voltage (VWM) of 16 V, meaning it remains non-conductive under normal operating conditions up to this reverse voltage. This parameter ensures minimal leakage current (<1.0 μA) while providing sufficient margin below the 17.8–19.7 V breakdown range for stable system operation.
Does the SMA6J16AH meet ISO 7637-2 immunity requirements?
Yes, the SMA6J16AH is specified to meet ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b test requirements. Its 600W peak pulse power rating and controlled clamping behavior enable compliant protection of 12V and 24V automotive supply rails against conducted transients generated by switching loads and battery disconnection events.
What package type does the SMA6J16AH use, and what are its key mechanical attributes?
The SMA6J16AH uses the DO-214AC (SMA) surface-mount package with matte tin-plated leads, UL 94V-0 rated molding compound, and cathode band polarity marking. Its weight is approximately 0.060 g, and it complies with JESD 201 Class 2 whisker testing and J-STD-020 Moisture Sensitivity Level 1-enabling standard reflow without pre-baking.
