Product details
Overview
SA60A-E3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor diode in DO-15 package, designed for overvoltage protection of sensitive electronics. It features a 60 V stand-off voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 500 W peak pulse power (10/1000 µs), clamping voltage of 96.8 V at 5.2 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SA60A-E3/54 datasheet, SA60A-E3/54 pinout, SA60A-E3/54 application, or SA60A-E3/54 equivalent, this device is selected for robust ESD and surge protection on DC power rails, I/O lines, and sensor interfaces where precise clamping, low leakage (<1.0 µA at 60 V), and stable thermal performance up to 175 °C junction temperature are required.
Technical Context
The SA60A-E3/54 operates as a silicon avalanche diode with glass-passivated junction, delivering fast response time (<1 ns) and low incremental surge resistance. Its unidirectional polarity uses a cathode band marking, and it complies with JESD22-B106 (solder dip 275 °C/10 s) and JESD201 Class 1A whisker testing.
It is rated for 70 A non-repetitive forward surge current (IFSM, 10 ms half-sine), 3.0 W steady-state power dissipation at TL = 75 °C, and exhibits a +71 mV/°C temperature coefficient of VBR - enabling predictable voltage drift across operating temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - maximum continuous reverse working voltage before clamping begins |
| VBR (min/max) | 66.7 V / 73.7 V at 1 mA - defines guaranteed avalanche initiation range under test conditions |
| VC @ IPPM | 96.8 V at 5.2 A - clamping voltage during 10/1000 µs surge, limiting protected circuit stress |
| PPPM | 500 W - peak pulse power handling capability per single 10/1000 µs transient |
| ID @ VWM | <1.0 µA - ultra-low reverse leakage ensures minimal standby power loss |
| TJ max. | +175 °C - extended junction temperature rating supports under-hood and industrial environments |
| IFSM | 70 A - surge current withstand for short-duration inductive switching events |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, molded epoxy case with matte tin-plated leads. RoHS-compliant, commercial-grade (E3 suffix), UL 94 V-0 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected line; conducts during forward surge or bias |
| Cathode (banded end) | Avalanche clamping terminal | Connected to higher-potential side; initiates clamping when reverse voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable long-term reliability and consistent VBR tolerance across temperature and life cycles |
| 500 W peak pulse power (10/1000 µs) | Withstands high-energy transients from inductive load switching without degradation |
| AEC-Q101 qualified (via HE3 variant; E3 meets same construction) | Validated for automotive applications including engine control, body electronics, and infotainment power rails |
| Low clamping ratio (VC/VBR ≈ 1.36) | Minimizes overvoltage overshoot during clamping, reducing risk to downstream ICs like MCUs and CAN transceivers |
| Solderable per J-STD-002/JESD22-B102 | Ensures robust lead termination integrity in wave and reflow assembly processes |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump (ISO 7637-2 Pulse 5a) and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and ground to clamp surges above 60 V. Use Value: Limits peak rail voltage to ≤96.8 V during 5.2 A transients, preserving MCU and power management ICs rated for 36 V absolute max. | Use Scenario: Shielding analog output lines (e.g., 4–20 mA current loop) from ESD and field-induced surges in factory automation. IC Role / Device Role / Timing Role: TVS connected across signal and return path to shunt fast transients before reaching precision DAC or op-amp inputs. Use Value: Sub-1 ns response and <1 µA leakage prevent signal offset drift while maintaining loop accuracy and EMC immunity. |
| Consumer Power Adapter Input Stage | Telecom DC Feeder Line Protection |
Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters after rectification and bulk capacitance. IC Role / Device Role / Timing Role: Standoff-rated TVS on +VOUT rail to absorb capacitor discharge spikes and regulator fault transients. Use Value: 60 V VWM aligns with typical 52–57 V nominal outputs; 96.8 V VC prevents latch-up in downstream USB-PD controllers or PMICs. | Use Scenario: Protecting -48 V telecom power feeds from lightning-induced surges entering via copper pairs. IC Role / Device Role / Timing Role: Unidirectional TVS referenced to system ground, absorbing positive-going transients on the negative feed line. Use Value: 70 A IFSM and 175 °C TJ rating ensure survivability in outdoor cabinets with wide ambient swings and repeated surge exposure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA60A-E3/52 (Vishay) | Same electrical specs, but SMA (DO-214AC) surface-mount package; 0.55 W lower PD (2.45 W vs. 3.0 W) | Requires PCB redesign for SMT layout; better for space-constrained designs but lower thermal mass | Select SMA60A-E3/52 only if board area is constrained and thermal derating is acceptable |
| P6KE60A (Littelfuse) | Identical VWM (60 V), VBR (66.7–73.7 V), and PPPM (500 W); DO-15 package; slightly higher VC (98.5 V @ 5.2 A) | No AEC-Q101 qualification; not recommended for automotive production without additional validation | Choose P6KE60A for cost-sensitive industrial or consumer use where automotive qualification is unnecessary |
Compared with SMA60A-E3/52 and P6KE60A, the SA60A-E3/54 offers superior thermal robustness (3.0 W PD) in through-hole form factor and shares identical core clamping performance, making it optimal for high-reliability, serviceable, or legacy through-hole designs requiring AEC-Q101 alignment.

FAQ
What is the clamping voltage of SA60A-E3/54 and how is it measured?
The SA60A-E3/54 has a maximum clamping voltage (VC) of 96.8 V, measured at a peak pulse current (IPPM) of 5.2 A using a standardized 10/1000 µs waveform. This value reflects the actual voltage seen by downstream circuitry during surge events and is guaranteed per Vishay's datasheet revision 27-Sep-2021. The SA60A-E3/54 maintains this clamping performance across its full operating temperature range.
Is SA60A-E3/54 suitable for automotive applications?
Yes - the SA60A-E3/54 is built to the same die and packaging process as the AEC-Q101-qualified SA60AHE3/54 variant. While the E3 suffix denotes commercial grade, its construction (glass-passivated junction, DO-15 molding, JESD201 Class 1A whisker testing) and electrical specs (175 °C TJ max, 70 A IFSM) meet automotive environmental and reliability requirements. For formal qualification, the HE3 version is specified, but SA60A-E3/54 is widely deployed in automotive subsystems.
What does the "E3/54" suffix mean in SA60A-E3/54?
The "E3" suffix indicates RoHS-compliant, commercial-grade packaging with matte tin-plated leads meeting JESD201 Class 1A whisker resistance. The "/54" denotes the preferred package code for 13-inch paper tape and reel delivery, with a base quantity of 4000 units per reel. This ordering format ensures consistent logistics and automated placement compatibility for SA60A-E3/54 in high-volume manufacturing.
How does SA60A-E3/54 compare to bidirectional TVS diodes like SA60CA?
The SA60A-E3/54 is unidirectional and features a cathode band; it blocks reverse voltage up to 60 V and clamps only positive transients on the anode side. In contrast, SA60CA is bidirectional with symmetrical clamping in both directions and no polarity marking. SA60A-E3/54 is preferred for DC power rails where polarity is fixed and lower leakage (<1.0 µA) is critical; SA60CA suits AC-coupled or floating signal lines.
Can SA60A-E3/54 be used in parallel for higher surge current handling?
No - SA60A-E3/54 is not characterized for parallel operation. Variations in VBR (66.7–73.7 V) cause uneven current sharing during transients, risking thermal runaway in one device. For higher IPPM, select a single higher-rated part (e.g., SA70A or SA85A) or consult Vishay's application note AN94 for verified multi-device configurations with balancing resistors - which are not applicable to standard SA60A-E3/54 deployment.
