Product details
Overview
SA6V0A-T from Diodes Incorporated is a unidirectional 500W transient voltage suppressor (TVS) diode in DO-15 package, rated for 6.0V reverse standoff voltage, 6.67–7.37V breakdown at 10mA, and clamping voltage of 10.3V at 48.5A peak pulse current. It operates from –65°C to +175°C and is used for primary overvoltage protection in DC power rails and I/O interfaces.
For engineers reviewing the SA6V0A-T datasheet, SA6V0A-T pinout, SA6V0A-T application, or SA6V0A-T equivalent, key selection criteria include clamping voltage margin vs. protected IC VMAX, peak pulse current capability under 10/1000µs waveform, thermal derating above 75°C lead temperature, and RoHS-compliant matte tin plating compatibility with lead-free reflow.
Technical Context
This TVS diode employs a glass-passivated silicon junction optimized for fast response (<1 ps typical) to ESD and surge transients per IEC 61000-4-2 (±30 kV contact) and IEC 61000-4-5 (40 A 8/20 µs). Its unidirectional configuration provides low-capacitance protection on positive-rail lines without reverse-bias leakage concerns.
The device is characterized using a 10×1000 µs double-exponential pulse (RE-A definition), with peak power derated linearly from 500W at TL = 25°C to zero at TL = 175°C. Clamping performance is guaranteed across the full operating temperature range with ±5.0 mV/°C VBR drift coefficient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 500 W @ 10×1000 µs waveform - sustains single high-energy surges without failure |
| Reverse Standoff Voltage (VR) | 6.0 V - maximum continuous DC voltage before significant leakage begins |
| Breakdown Voltage (VBR) | 6.67–7.37 V @ 10 mA - ensures reliable triggering above normal rail noise |
| Clamping Voltage (VC) | 10.3 V @ 48.5 A - limits transient voltage seen by downstream circuitry |
| Peak Pulse Current (IPP) | 48.5 A @ 10×1000 µs - quantifies surge-handling capacity under standard test condition |
| Operating Temperature | –65°C to +175°C - supports automotive under-hood and industrial ambient environments |
| Leakage Current (IR) | 600 µA @ 6.0 V - minimal standby power loss and signal integrity impact |
Pinout & Package
DO-15 axial-leaded package: molded plastic case (UL 94V-0), 9.5 mm lead length (board-mounted), 0.4 g mass. Cathode band denotes terminal polarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or return path; defines conduction direction in unidirectional mode |
| Cathode | High-side connection point | Connected to protected line; conducts during overvoltage events to clamp to VC |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die construction | Enables stable VBR and low leakage across temperature and lifetime |
| 500W peak pulse rating | Meets IEC 61000-4-5 Level 4 (4 kV) surge immunity requirements |
| Fast response time | <1 ps junction response - clamps before sensitive logic or analog circuitry is stressed |
| RoHS-compliant matte tin plating | Compatible with Pb-free reflow profiles up to 260°C peak, per J-STD-020C |
| Unidirectional configuration | Eliminates reverse-bias leakage risk on positive-rail applications like 5V/3.3V supply lines |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Card |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P6KE6V8A | Same DO-15 package; 6.8V VR, 7.63–8.44V VBR, 10.5V VC @ 47.6A | Slightly higher clamping voltage and lower IPP; designed for legacy P6KE series footprint compatibility | Select when replacing obsolete SA6V0A-T in existing P6KE-layout boards with minimal layout change |
| SMAJ6.0A | SMA package (surface-mount); 6.0V VR, 6.67–7.37V VBR, 10.3V VC @ 48.5A - identical electrical specs | Requires PCB redesign for SMD placement; eliminates axial lead assembly and improves board density | Prefer for new designs requiring automated assembly, space-constrained layouts, or improved thermal coupling to copper pour |
Compared with SA6V0A-T, P6KE6V8A offers mechanical interchangeability but trades 0.2V lower clamping margin, while SMAJ6.0A delivers identical protection performance in a surface-mount format-enabling higher reliability in vibration-prone environments and eliminating through-hole solder void risks.

FAQ
Is SA6V0A-T RoHS compliant and lead-free?
Yes. SA6V0A-T features matte tin-plated leads and conforms to RoHS Directive 2011/65/EU (Annex III exemptions applied per EU Directive Annex Notes 5 and 7). It is qualified for lead-free reflow up to 260°C peak temperature per J-STD-020C.
What is the maximum allowable lead temperature during soldering?
The maximum lead temperature for SA6V0A-T is 260°C for 10 seconds during hand soldering or wave soldering. For reflow, the peak temperature must not exceed 260°C, with time above 217°C limited to 60–150 seconds per J-STD-020C Level 1 profile.
Can SA6V0A-T be used in bidirectional configurations?
No. SA6V0A-T is unidirectional only (suffix "A"). Bidirectional variants use the "CA" suffix (e.g., SA6V0CA). Using SA6V0A-T in reverse-biased configurations will result in premature breakdown and potential failure due to lack of symmetrical clamping capability.
How does SA6V0A-T compare to SA6V0A (bulk) in electrical performance?
SA6V0A-T (tape-and-reel) and SA6V0A (bulk) share identical electrical specifications, thermal characteristics, and packaging dimensions. The only difference is packaging format: SA6V0A-T ships in 4,000-piece 13-inch tape-and-reel reels per AP02008 specification, enabling automated pick-and-place assembly.
