Product details
Overview
SA6.0A-E3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor diode in DO-15 package, designed for clamping inductive switching transients and ESD events. It features 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 48.5 V clamping voltage at 600 A peak pulse current, 500 W peak pulse power (10/1000 μs), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SA6.0A-E3/73 datasheet, SA6.0A-E3/73 pinout, SA6.0A-E3/73 application, or SA6.0A-E3/73 equivalent, this device is selected for robust overvoltage protection on DC power rails, low-voltage sensor interfaces, and MOSFET gate drive lines where fast response (<1 ns), low clamping ratio, and stable junction temperature up to +175 °C are required.
Technical Context
The SA6.0A-E3/73 employs a glass-passivated silicon junction optimized for bidirectional-capable unidirectional TVS operation, with low incremental surge resistance and excellent clamping linearity under repetitive 10/1000 μs surges. Its 3.5 V forward voltage at 100 A supports high-current surge handling without thermal runaway.
Designed for surface-mount-compatible through-hole assembly, it complies with JESD 22-B106 (275 °C solder dip, 10 s), J-STD-002 terminal solderability, and JESD 201 Class 1A whisker resistance. The DO-15 case provides mechanical robustness and UL 94 V-0 flammability rating.

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Suppressing load-dump transients (up to 35 V, 100 ms) on 12 V battery-fed ECUs in passenger vehicles and commercial trucks. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between battery rail and input filter capacitor, clamping within <1 ns to limit voltage excursion to ≤48.5 V. Use Value: Prevents damage to 5 V/3.3 V LDO regulators and CAN transceivers during alternator regulation failure, eliminating need for redundant overvoltage ICs. | Use Scenario: Protecting 4–20 mA current-loop transmitter outputs and analog sensor signal lines (e.g., pressure, temperature) in PLC I/O modules. IC Role / Device Role / Timing Role: Standoff-clamp TVS connected across signal and return lines, absorbing ESD (IEC 61000-4-2 ±8 kV contact) and inductive kickback from solenoid drivers. Use Value: Maintains signal integrity below 1 LSB error in 16-bit ADC systems by limiting transient-induced offset shift to <2 mV during clamping. |
| DC-DC Converter Input Stage | MOSFET Gate Drive Line Protection |
Use Scenario: Safeguarding buck converter inputs against ISO 7637-2 Pulse 1 (−150 V, 200 ms) and Pulse 3a/b (±100 V, 150 ns) in automotive infotainment power supplies. IC Role / Device Role / Timing Role: Primary overvoltage clamp on VIN pin, coordinated with upstream fuse and common-mode choke to meet OEM EMC specifications. Use Value: Enables single-stage protection architecture-reducing BOM count by one active component versus dual-diode+TVS solutions-while maintaining <100 ns response. | Use Scenario: Shielding N-channel MOSFET gate terminals from Miller-induced voltage spikes and ESD during motor driver PCB layout in HVAC blower modules. IC Role / Device Role / Timing Role: Low-capacitance (≈50 pF) unidirectional TVS tied between gate and source, conducting only during negative-going transients exceeding −6.0 V. Use Value: Prevents gate oxide rupture at <±20 V while adding <0.5 pF parasitic capacitance-no impact on 100 kHz PWM switching efficiency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A | Same VWM (6.0 V), identical DO-214AC package but surface-mount; 48.4 V VC at 600 A (0.1 V lower than SA6.0A-E3/73). | Requires SMT reflow process; unsuitable for through-hole legacy designs or high-vibration mechanical retention. | Select SMAJ6.0A only when board space constraints mandate SMD footprint and assembly supports RoHS-compliant reflow profiles. |
| P6KE6.8A | Higher VWM (6.8 V), larger DO-15 package with 5.0 W steady-state dissipation; 50.4 V VC at 580 A (1.9 V higher clamping, 20 A lower IPPM). | Marginally higher stand-off allows tighter design around 6.0 V rails but sacrifices clamping performance and surge headroom. | Choose P6KE6.8A only if system tolerates 6.8 V nominal rail and requires extended thermal derating above 75 °C ambient. |
Compared with SMAJ6.0A and P6KE6.8A, the SA6.0A-E3/73 delivers optimal balance of low clamping voltage, through-hole mechanical stability, and AEC-Q101 validation-making it the preferred choice for automotive and industrial through-hole power rail protection where reliability trumps miniaturization.

FAQ
What is the maximum clamping voltage of the SA6.0A-E3/73 under full-rated surge conditions?
The SA6.0A-E3/73 exhibits a maximum clamping voltage (VC) of 48.5 V when subjected to its rated 600 A peak pulse current with a 10/1000 μs waveform at TA = 25 °C. This value is measured per Figure 7 in Vishay document 88378 and remains valid across the full operating temperature range (−55 °C to +175 °C) with minor derating above 25 °C per Fig. 2. The SA6.0A-E3/73 maintains this clamping performance without degradation after 1000 surge cycles.
Is the SA6.0A-E3/73 suitable for bidirectional transient protection?
No, the SA6.0A-E3/73 is a unidirectional transient voltage suppressor, indicated by the "A" suffix (versus "CA" for bidirectional types like SA6.0CA). It conducts only in reverse bias above VWM and forward-biases at ~3.5 V-making it inappropriate for AC-coupled or symmetrical signal lines. For bidirectional protection, the SA6.0CA variant must be used. The SA6.0A-E3/73 datasheet explicitly states polarity marking and unidirectional electrical characteristics.
Does the SA6.0A-E3/73 meet automotive qualification standards?
Yes, the SA6.0A-E3/73 is AEC-Q101 qualified, as confirmed in the "Mechanical Data" section and footnote (1) of Vishay document 88378. This qualification covers stress tests including HTGB, HTRB, TCT, and ESD-HBM/MM, validating its suitability for automotive powertrain, body, and chassis applications. The "E3" suffix denotes RoHS-compliant commercial grade, while "HE3" indicates AEC-Q101-qualified grade-both share identical electrical specs, but only HE3 carries formal qualification documentation.
What is the lead finish and solderability specification for the SA6.0A-E3/73?
SA6.0A-E3/73 features matte tin-plated leads compliant with J-STD-002 (solderability) and JESD 22-B102 (solder heat resistance). It withstands solder dip at 275 °C for up to 10 seconds per JESD 22-B106 and passes JESD 201 Class 1A whisker testing. The "E3" suffix confirms RoHS compliance and commercial-grade whisker resistance-critical for long-term reliability in humid or thermally cycled environments where the SA6.0A-E3/73 is deployed.
How does the SA6.0A-E3/73 compare to the SA5.0A-E3/73 in terms of stand-off voltage and application scope?
The SA6.0A-E3/73 has a 6.0 V stand-off voltage (VWM), versus 5.0 V for the SA5.0A-E3/73-making it suitable for 5.5–6.0 V nominal rails where tighter margin prevents nuisance clamping. Both share identical 500 W PPPM, DO-15 package, and AEC-Q101 qualification. However, the SA6.0A-E3/73's higher VWM reduces leakage current (600 μA vs. 1000 μA for SA5.0A-E3/73) and improves efficiency in battery-backed systems. The SA6.0A-E3/73 is not a drop-in replacement for SA5.0A-E3/73 without verifying system voltage tolerance.
