Product details
Overview
SMA6J17A R3G from Taiwan Semiconductor is a 600W surface-mount transient voltage suppressor (TVS) diode with a working standoff 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, designed for surge protection in DC/DC converters and automotive power systems.
For engineers reviewing the SMA6J17A R3G datasheet, SMA6J17A R3G pinout, SMA6J17A R3G application, or SMA6J17A R3G equivalent, key selection criteria include its DO-214AC (SMA) package, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, 1.0 ps typical response time, and 175°C maximum junction temperature-critical for ruggedized industrial and automotive power rail protection.
Technical Context
This unidirectional TVS diode operates as a reverse-biased avalanche clamp, activated when transient voltage exceeds its breakdown threshold (VBR = 18.9–20.9 V @ 1 mA). It delivers 600 W peak pulse power under 10/1000 μs waveform while maintaining clamping voltage ≤26.7 V at 1.0 A IPPM.
Its glass-passivated junction ensures stable leakage performance (<1.0 µA @ VWM), and it meets JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1-enabling reliable automated SMT assembly without baking.

| VBR min/max | 18.9 V / 20.9 V @ 1 mA - Confirmed avalanche onset range for reliable overvoltage triggering |
| VC @ IPPM | 26.7 V @ 1.0 A - Clamped voltage during full-rated surge, limiting downstream stress |
| PPPM | 600 W @ 10/1000 μs - Peak surge energy handling capacity per industry-standard waveform |
| TJ max | +175 °C - Enables operation in high-temperature engine bay or industrial power environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J17AHE3_A/H (Vishay) | Same DO-214AC package, identical VWM/VBR/VC specs, but RoHS-compliant with halogen-free epoxy only (no IEC 61249-2-21 certification stated) | Valid for general industrial use; lacks explicit ISO 7637-2 test documentation in public datasheet | Select when ISO 7637-2 validation is not required and Vishay supply chain preference applies |
| P6SMB17A (ON Semiconductor) | Same 17 V VWM, but lower PPPM = 600 W (same rating), higher VC = 27.6 V @ 1.0 A, and wider VBR tolerance (18.9–22.1 V) | Suitable for non-automotive applications where 0.9 V higher clamping is acceptable | Choose if tighter VBR tolerance (±5.3%) of SMA6J17A R3G is critical for precise trip margin control |
Compared with SMA6J17AHE3_A/H and P6SMB17A, the SMA6J17A R3G offers the narrowest VBR tolerance (±5.3%), explicit ISO 7637-2 validation, and certified halogen-free status per IEC 61249-2-21-making it preferred for automotive Tier-1 power rail designs requiring traceable compliance.

FAQ
What is the maximum clamping voltage of the SMA6J17A R3G under rated surge conditions?
The SMA6J17A R3G has a maximum clamping voltage (VC) of 26.7 V when subjected to its rated peak pulse current of 1.0 A using the 10/1000 μs waveform. This value is measured per standard test conditions and ensures downstream components remain within safe operating voltage limits during transient events.
Does the SMA6J17A R3G meet automotive EMC standards?
Yes, the SMA6J17A R3G is explicitly tested and compliant with ISO 7637-2 for automotive transient immunity, covering Pulse 1 (load dump), Pulse 2a/2b (supply disconnection and switching), and Pulse 3a/3b (capacitive coupling and line spikes). This makes it suitable for ECU and body control module power rail protection.
What is the moisture sensitivity level (MSL) rating for SMA6J17A R3G?
The SMA6J17A R3G carries a Moisture Sensitivity Level (MSL) rating of Level 1 per J-STD-020, meaning it can be stored indefinitely at ambient conditions (≤30°C / 60% RH) without baking prior to reflow soldering-ideal for just-in-time SMT manufacturing workflows.
Is the SMA6J17A R3G RoHS and halogen-free compliant?
Yes, the SMA6J17A R3G is RoHS compliant and certified halogen-free per IEC 61249-2-21. Its molding compound contains no brominated flame retardants or chlorine-based additives, supporting environmental compliance requirements for automotive and industrial end equipment.
What is the operating junction temperature range for SMA6J17A R3G?
The SMA6J17A R3G supports an operating junction temperature range of –55°C to +175°C. This wide range enables deployment in under-hood automotive locations, industrial motor drives, and other high-ambient-temperature environments where thermal derating must be minimized.
