Product details
Overview
SMA6J16A R3G from Taiwan Semiconductor is a 600W surface-mount transient voltage suppressor (TVS) diode with a working standoff voltage of 16 V, breakdown voltage range 17.8–19.7 V, and clamping voltage of 25.2 V at 23.8 A peak pulse current under 10/1000 µs waveform; used for surge protection in DC/DC converters and automotive power supplies.
For engineers reviewing the SMA6J16A R3G datasheet, SMA6J16A R3G pinout, SMA6J16A R3G application, or SMA6J16A R3G equivalent, key selection criteria include clamping voltage (25.2 V), peak pulse power (600 W), junction temperature range (−55 °C to +175 °C), compliance with ISO 7637-2 Pulse 1/2a/2b/3a/3b, and DO-214AC (SMA) package compatibility.
Technical Context
The SMA6J16A R3G is a unidirectional, single-die TVS diode designed for fast transient suppression in low-voltage DC power rails. It features glass-passivated junction construction, <1.0 ps response time, and meets JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1 requirements.
Its electrical behavior follows standard TVS diode characteristics: reverse-biased operation with sharp avalanche breakdown above VBR, low leakage (<1.0 µA at 16 V), and stable clamping performance across −55 °C to +175 °C operating junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - Maximum continuous reverse voltage before significant leakage; defines safe operating DC rail limit. |
| VBR @ IT=1 mA | 17.8–19.7 V - Breakdown onset range; ensures reliable turn-on during transients exceeding 16 V. |
| VC @ IPPM=23.8 A | 25.2 V - Clamped voltage during 10/1000 µs surge; limits downstream IC stress to ≤25.2 V. |
| PPPM | 600 W - Peak pulse power handling per 10/1000 µs waveform; supports high-energy automotive load dump events. |
| TJ Range | −55 °C to +175 °C - Full industrial/automotive junction temperature range; enables under-hood deployment. |
| Package | DO-214AC (SMA) - Standardized surface-mount outline with cathode band polarity marking and 0.060 g mass. |
Pinout & Package
DO-214AC (SMA) package: molded plastic case with matte tin-plated leads, UL 94V-0 rated compound, cathode indicated by band. Polarity-critical for unidirectional TVS operation.

Applications
| Automotive Body Control Module (BCM) | Industrial DC/DC Converter Input Stage |
|---|---|
Use Scenario: Protects microcontroller I/O and CAN transceiver power rails from load dump and jump-start surges in 12 V vehicle systems. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between 16 V supply rail and ground to shunt transient energy before it reaches downstream regulators. Use Value: Limits voltage excursion to 25.2 V during 600 W pulses, preventing latch-up or gate oxide damage in 3.3 V/5 V logic devices. | Use Scenario: Shields primary-side controller ICs and MOSFET gates from switching-induced spikes in isolated flyback or buck-boost converters. IC Role / Device Role / Timing Role: Standoff-rated TVS connected across input capacitor terminals to absorb reflected energy from transformer leakage inductance.

| LED Driver Power Input | USB-C PD Adapter Secondary Side |
Use Scenario: Guards constant-current LED driver ICs against ESD and lightning-induced surges on 12–24 V input lines in outdoor lighting fixtures. IC Role / Device Role / Timing Role: Primary overvoltage protection element located immediately after input connector, before bulk capacitance and EMI filter. Use Value: Withstands repeated 10/1000 µs transients up to 600 W without degradation, ensuring >10-year field life in harsh environments. | Use Scenario: Safeguards secondary-side synchronous rectifier controllers and output monitoring circuits in compact USB-C power adapters. IC Role / Device Role / Timing Role: Low-capacitance TVS placed across 16 V bias rail feeding optocoupler feedback circuitry. Use Value: Delivers 25.2 V clamping with <1.0 µA leakage at 16 V, avoiding interference with precision voltage feedback loops. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J16AHE3_A/H (Vishay) | Same DO-214AC package, identical VWM/VBR/VC specs, but rated for higher IFSM (60 A vs. 50 A). | Better suited for systems requiring higher single-pulse forward surge tolerance, e.g., alternator load dump with extended duration. | Select when surge current margin beyond 50 A is required; otherwise, SMA6J16A R3G offers full functional equivalence. |
| P6SMB16A (ON Semiconductor) | Same 16 V VWM, but lower PPPM (600 W same), slightly higher VC (26.0 V vs. 25.2 V), and wider VBR tolerance (17.8–20.8 V). | Marginally reduced clamping headroom may impact 3.3 V logic protection in tight-margin designs. | Acceptable where 0.8 V higher clamping is tolerable; verify downstream device absolute maximum ratings before substitution. |
Compared with SMA6J16AHE3_A/H and P6SMB16A, the SMA6J16A R3G provides the tightest VBR range (17.8–19.7 V) and lowest clamping voltage (25.2 V), delivering superior voltage limiting precision for noise-sensitive or low-voltage tolerant circuits.

FAQ
What is the clamping voltage of the SMA6J16A R3G at its rated peak pulse current?
The SMA6J16A R3G has a maximum clamping voltage (VC) of 25.2 V at 23.8 A peak pulse current under the standardized 10/1000 µs waveform. This value is measured per JEDEC test conditions and guarantees that protected circuitry will not experience voltages exceeding 25.2 V during a 600 W transient event. The SMA6J16A R3G maintains this clamping performance across its full operating temperature range.
Does the SMA6J16A R3G meet automotive surge immunity standards?
Yes, the SMA6J16A R3G meets ISO 7637-2 requirements for Pulse 1, 2a, 2b, 3a, and 3b, making it suitable for 12 V automotive power network protection. Its 600 W peak pulse power rating, −55 °C to +175 °C junction temperature range, and glass-passivated junction ensure robustness against load dump, jump-start, and coupled transients. The SMA6J16A R3G is explicitly qualified for these tests per Taiwan Semiconductor's E2102 specification document.
What is the package type and polarity marking of the SMA6J16A R3G?
The SMA6J16A R3G uses the DO-214AC (SMA) surface-mount package with matte tin-plated leads and a cathode band marking the cathode terminal. The anode is the unmarked end. This polarity is critical because the SMA6J16A R3G is a unidirectional TVS diode-reverse-biased during normal operation and conducting only when the cathode-to-anode voltage exceeds the breakdown threshold. The SMA6J16A R3G's DO-214AC footprint matches industry-standard layouts for automated placement.
How does the SMA6J16A R3G compare to the SMA6J15A in terms of voltage ratings?
The SMA6J16A R3G has a working standoff voltage (VWM) of 16 V and breakdown voltage range of 17.8–19.7 V, whereas the SMA6J15A specifies VWM = 15 V and VBR = 16.7–18.5 V. The SMA6J16A R3G provides higher DC blocking capability and tighter VBR tolerance, making it preferable for 16 V nominal rails where margin above 15 V is required. Both share identical 600 W PPPM, DO-214AC package, and thermal ratings.
Is the SMA6J16A R3G RoHS and halogen-free compliant?
Yes, the SMA6J16A R3G is RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound meets UL 94V-0 flammability rating, and its matte tin-plated leads are solderable per J-STD-002. These compliance attributes are confirmed in Taiwan Semiconductor's E2102 datasheet revision and apply directly to the SMA6J16A R3G manufacturing lot. No exemptions or exceptions apply to the SMA6J16A R3G.
