Product details
Overview
SMA6J10AHR3G from Taiwan Semiconductor is a 600W surface-mount transient voltage suppressor (TVS) diode with 10V working standoff voltage, 11.1–12.3V breakdown voltage at 1mA, and 38.2V maximum clamping voltage at 5.0A peak pulse current. It uses a DO-214AC (SMA) package and is designed for surge protection in DC/DC converters and automotive power supplies.
For engineers reviewing the SMA6J10AHR3G datasheet, SMA6J10AHR3G pinout, SMA6J10AHR3G application, or SMA6J10AHR3G equivalent, key selection criteria include clamping voltage under 10/1000μs surge, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, moisture sensitivity level 1 rating, and RoHS/halogen-free qualification.
Technical Context
This unidirectional TVS diode features a glass-passivated silicon junction and responds to transients in less than 1.0ps. Its single-die configuration delivers precise clamping performance with 5.0μA max reverse leakage at 10V and 175°C maximum junction temperature.
The device operates across –55°C to +175°C and sustains 50A non-repetitive forward surge current (8.3ms half-sine). Its DO-214AC package supports automated placement and meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J10AHE3/61 | Same electrical specs; differs only in tape-and-reel packaging (7,500 pcs vs. 3,000 pcs) | No functional difference; identical mounting and thermal behavior | Select based on volume procurement needs and assembly line reel compatibility |
| SMCJ10A | Higher PPPM = 1500W; larger DO-214AB (SMB) package; VC = 17.0V @ 53.3A | Better suited for higher-energy surges but requires PCB area increase and layout revision | Choose SMA6J10AHR3G when space-constrained designs demand 600W capability in minimal footprint |
Compared with SMA6J10AHE3/61, SMA6J10AHR3G offers identical protection performance in a different reel configuration; versus SMCJ10A, it trades peak power for DO-214AC size reduction-critical for compact adapters and automotive ECUs where board area is premium.

FAQ
What is the maximum clamping voltage of SMA6J10AHR3G at its rated peak pulse current?
The SMA6J10AHR3G has a maximum clamping voltage (VC) of 38.2 V when subjected to its rated peak pulse current of 5.0 A under the standard 10/1000μs waveform. This value is measured per JEDEC test conditions and ensures predictable overvoltage limiting for downstream components in the SMA6J10AHR3G protection circuit.
Does SMA6J10AHR3G meet automotive surge immunity standards?
Yes, SMA6J10AHR3G meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b requirements for transient immunity in 12V automotive systems. Its verified clamping performance, fast response time (<1.0 ps), and 175°C junction rating make it suitable for engine control units, body electronics, and infotainment power rails where SMA6J10AHR3G is deployed.
What is the moisture sensitivity level (MSL) rating for SMA6J10AHR3G?
SMA6J10AHR3G is rated MSL Level 1 per J-STD-020, meaning it may be stored indefinitely at ambient conditions and does not require baking prior to surface-mount reflow. This simplifies manufacturing flow and eliminates yield risk from moisture-related popcorning during soldering of the SMA6J10AHR3G device.
How does the DO-214AC package of SMA6J10AHR3G compare to DO-214AB in size and thermal performance?
The DO-214AC (SMA) package of SMA6J10AHR3G measures 4.5 × 2.7 × 2.1 mm, smaller than DO-214AB (SMB) at 5.3 × 3.6 × 2.3 mm. While SMA6J10AHR3G's thermal resistance is higher (RθJA ≈ 120°C/W vs. ~80°C/W for SMB), its 600W rating remains valid under short-duration pulses due to low thermal mass and optimized junction design.
Is SMA6J10AHR3G halogen-free and RoHS compliant?
Yes, SMA6J10AHR3G is both RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, supporting environmental compliance for export to EU, China, and other regulated markets where SMA6J10AHR3G is specified in end-product BOMs.
