Product details
Overview
SA6.0A from Taiwan Semiconductor is a unidirectional 500W transient voltage suppressor (TVS) diode with 6.67–7.37V breakdown voltage, 6.0V working stand-off voltage, and 50.0A peak pulse current at 10/1000μs waveform. It features low clamping voltage (10.3V), fast response (<1.0ps), and DO-204AC (DO-15) package for automotive and industrial overvoltage protection.
For engineers reviewing the SA6.0A datasheet, SA6.0A pinout, SA6.0A application, or SA6.0A equivalent, this page delivers verified electrical parameters, polarity-aware terminal mapping, AEC-Q101 qualification status, clamping performance under standardized surge waveforms, and real-world ESD/inductive load protection use cases.
Technical Context
The SA6.0A operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its VBR range (6.67–7.37V at 10mA test current). Its clamping action limits transient energy to ≤10.3V at 50.0A, enabling robust protection of downstream 5V–6V logic interfaces and power rails.
Designed for non-repetitive 10/1000μs surges up to 500W, it sustains 70A single half-sine forward surge (8.3ms), exhibits <1μA leakage above 10V, and maintains stable operation across –55°C to +175°C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before conduction begins; sets system-level overvoltage trip threshold. |
| VBR min/max | 6.67 V / 7.37 V @ 10 mA - Confirmed breakdown window ensures reliable turn-on without premature leakage or delayed clamping. |
| VC @ IPPM | 10.3 V @ 50.0 A - Clamping voltage during full-rated 500W surge; defines worst-case voltage seen by protected IC. |
| IPPM | 50.0 A - Peak pulse current capability at 10/1000μs waveform; directly supports IEC 61000-4-5 Level 4 immunity testing. |
| TJ max | +175 °C - Maximum junction temperature rating enables deployment in under-hood automotive and high-ambient industrial environments. |
| Leakage IR | <1 μA @ 6.0 V - Ultra-low reverse leakage preserves battery life and signal integrity in always-on circuits. |
| Response time | <1.0 ps - Sub-picosecond turn-on ensures protection against nanosecond-scale ESD events per IEC 61000-4-2. |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with cathode band marking for unidirectional polarity. Meets UL 94V-0 flammability and JESD 201 Class 2 whisker resistance standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Surge return path | Connected to ground or low-impedance return plane; completes clamping loop during transients. |
| Cathode | Reverse-biased input / Protected line connection | Connected to line being protected (e.g., 5V rail); conducts only when VKA ≥ VBR. |
Key Features

Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting LIN bus transceivers and microcontroller I/O pins from load dump and alternator ripple in 12V vehicle systems. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VCC and GND to clamp positive-going transients while blocking reverse conduction. Use Value: Limits voltage excursions to ≤10.3V during 500W surges, preserving 6V-rated CAN/LIN interface ICs and preventing latch-up. | Use Scenario: Shielding analog front-end inputs of pressure/temperature sensors in PLC modules exposed to relay coil flyback. IC Role / Device Role / Timing Role: Standoff protection device mounted at sensor connector to absorb inductive kickback before reaching ADC input stage. Use Value: Fast <1.0ps response captures sub-nanosecond edge transients; 6.0V VWM avoids interference with 5V sensor supply rails. |
| LED Driver Output Protection | USB Port ESD Suppression |
Use Scenario: Safeguarding constant-current LED driver outputs against open-circuit voltage spikes during hot-plug or cable disconnect events. IC Role / Device Role / Timing Role: Unidirectional TVS connected anode-to-ground, cathode-to-driver output to clamp positive overshoot only. Use Value: 10.3V clamping prevents damage to MOSFET gate oxides and output capacitors rated for ≤12V DC working voltage. | Use Scenario: Adding secondary-level ESD protection on USB 2.0 D+/D− lines after primary TVS array, targeting ±8kV contact discharge per IEC 61000-4-2. IC Role / Device Role / Timing Role: Discrete unidirectional suppressor placed inline with data lines to limit transient voltage without adding capacitance-induced signal distortion. Use Value: Junction capacitance <100pF (typical at 0V) avoids USB 2.0 eye diagram degradation; <1μA leakage prevents bus pull-down errors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A | Same DO-214AC package; slightly higher VC (10.5V vs. 10.3V) and lower IPPM (48.2A vs. 50.0A). | Marginally reduced clamping performance; identical footprint but different thermal mass and leadframe geometry. | Select SMAJ6.0A only if DO-214AC SMT layout is required instead of axial DO-15 through-hole mounting. |
| P6SMB6.0A | DO-214AA package; VBR range 6.67–7.37V matches SA6.0A, but PPK rated at 600W (vs. 500W) and VC = 10.3V identical. | Higher surge rating allows extended duty cycle in repetitive transient environments; same clamping voltage enables direct functional substitution. | Choose P6SMB6.0A when system-level surge testing requires >500W headroom or when DO-214AA SMT placement is preferred. |
Compared with SMAJ6.0A and P6SMB6.0A, the SA6.0A offers optimal balance of axial-mount mechanical robustness, AEC-Q101 qualification, and precise 10.3V clamping-making it preferred for automotive harness-located protection where vibration resistance and proven qualification outweigh minor SMT footprint advantages.

FAQ
What is the breakdown voltage range of the SA6.0A?
The SA6.0A has a guaranteed breakdown voltage range of 6.67 V to 7.37 V at 10 mA test current, measured per ANSI/IEEE C62.35. This narrow VBR window ensures predictable turn-on behavior and minimizes variation in clamping onset across production lots, critical for consistent protection in 5V–6V system designs.
Is the SA6.0A suitable for automotive applications?
Yes, the SA6.0A is AEC-Q101 qualified and explicitly rated for automotive use. Its –55°C to +175°C operating junction temperature range, DO-204AC mechanical robustness, and compliance with load dump and ISO 7637-2 transient immunity requirements make it suitable for engine control units, body control modules, and infotainment power supplies where reliability under thermal and vibration stress is mandatory.
What is the maximum clamping voltage of the SA6.0A during a 500W surge?
The SA6.0A clamps to a maximum of 10.3 V at 50.0 A peak pulse current (10/1000μs waveform), corresponding to its full 500W surge rating. This value is measured under standardized conditions and represents the highest voltage imposed on the protected circuit during worst-case transient events, ensuring compatibility with 6V-tolerant ICs and regulators.
Does the SA6.0A have bidirectional capability?
No, the SA6.0A is a unidirectional TVS diode, indicated by the absence of "C" or "CA" suffix and confirmed by its single cathode band marking. It conducts only during positive transients applied to the cathode relative to anode. For bidirectional protection, select SA6.0CA or equivalent bipolar variants with symmetric VBR characteristics in both directions.
What packaging options are available for the SA6.0A?
The SA6.0A is supplied in DO-204AC (DO-15) axial package, available in 3,500-piece tape-and-reel (SA6.0A) and 1,500-piece ammo box (SA6.0A0G) configurations. The part marking includes date code (YWW) and factory code (F), with green compound (G) indicating RoHS/halogen-free compliance per IEC 61249-2-21.
