Product details
Overview
SMA6J16AHR3G from Taiwan Semiconductor is a 600W surface-mount transient voltage suppressor (TVS) diode with a 16V working standoff voltage (VWM), 17.8–19.7V breakdown voltage (VBR), and 25.2V maximum clamping voltage (VC) at 23.8A peak pulse current, designed for surge protection in DC/DC converters and automotive power systems.
For engineers reviewing the SMA6J16AHR3G datasheet, SMA6J16AHR3G pinout, SMA6J16AHR3G application, or SMA6J16AHR3G equivalent, key selection criteria include clamping performance under ISO 7637-2 Pulse 1/2a/2b/3a/3b, DO-214AC (SMA) package compatibility, and 175°C junction temperature rating for harsh-environment deployment.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction to achieve sub-1.0ps response time and stable clamping across repetitive transients. Its single-die DO-214AC configuration supports automated placement and meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity requirements.
The device operates within –55°C to +175°C junction temperature range and delivers 600W peak pulse power (10/1000μs waveform) with 4W steady-state dissipation. Polarity is indicated by cathode band; terminals are matte tin-plated for solderability per J-STD-002.

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-Q | AEC-Q200 qualified version; identical electrical specs but validated for automotive use | Required for ASIL-B compliant modules; not needed for industrial-only designs | Select SMA6J16A-Q only when automotive qualification is mandated |
| SMB6J16A | Same VWM/VBR/VC but in DO-214AA (SMB) package - 2.5mm wider body, higher thermal mass | Better thermal dissipation in high-ambient-temp PCB layouts; requires larger pad area | Choose SMB6J16A if board space allows and thermal margin is critical |
Compared with SMA6J16AHR3G, SMA6J16A-Q adds AEC-Q200 validation without electrical change, while SMB6J16A trades smaller footprint for improved thermal handling - both require layout review but offer verified alternatives for VWM=16V TVS needs.

FAQ
What is the clamping voltage of SMA6J16AHR3G at its rated peak pulse current?
The SMA6J16AHR3G has a maximum clamping voltage (VC) of 25.2 V at 23.8 A peak pulse current (IPPM), measured under the standard 10/1000 μs waveform. This value ensures downstream components see limited overvoltage during surge events, directly supporting design margin calculations for 3.3V, 5V, and 12V logic rails. The SMA6J16AHR3G datasheet specifies this parameter at TA = 25°C with defined test conditions.
Does SMA6J16AHR3G meet automotive surge immunity standards?
Yes, SMA6J16AHR3G meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b requirements for transient immunity in 12V and 24V automotive systems. Its 600W peak pulse power rating and sub-1.0ps response time enable compliance without external circuitry. While SMA6J16AHR3G itself is not AEC-Q200 certified, its electrical and mechanical specifications align with those standards - for full qualification, consider the pin-compatible SMA6J16A-Q variant.
What is the package type and mounting compatibility of SMA6J16AHR3G?
SMA6J16AHR3G uses the DO-214AC (SMA) surface-mount package with cathode band marking, matte tin-plated leads, and UL 94V-0 molding compound. It is compatible with standard reflow profiles per J-STD-020 Level 1 and supports automated pick-and-place. The SMA6J16AHR3G footprint matches industry-standard SMA land patterns, enabling drop-in replacement for other DO-214AC TVS diodes with matching voltage ratings.
What is the maximum operating temperature for SMA6J16AHR3G?
The SMA6J16AHR3G has a maximum junction temperature (TJ max) of +175°C and an operating junction temperature range of –55°C to +175°C. This enables reliable deployment in under-hood automotive locations, industrial motor drives, and outdoor power equipment. Derating curves in the SMA6J16AHR3G datasheet define allowable power dissipation versus ambient temperature for thermal design validation.
How does SMA6J16AHR3G compare to SMA6J15A in terms of voltage rating and clamping performance?
SMA6J16AHR3G has a 16V working standoff voltage (VWM) and 17.8–19.7V breakdown range, versus SMA6J15A's 15V VWM and 16.7–18.5V VBR. Clamping voltage rises from 23.6V (SMA6J15A) to 25.2V (SMA6J16AHR3G) at respective IPPM values, reflecting tighter voltage margin control for 16V nominal systems. Both share identical 600W PPPM and DO-214AC packaging, making SMA6J16AHR3G the preferred choice for 16V rail protection where precise VWM alignment is required.
