Product details
Overview
SA60CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 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), 5.2 A peak pulse current (IPPM), and clamps to ≤96.8 V at rated IPPM. It protects MOSFETs and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the SA60CA-E3/54 datasheet, SA60CA-E3/54 pinout, SA60CA-E3/54 application, or SA60CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, AEC-Q101 qualification, 175 °C max junction temperature, and low incremental surge resistance for robust ESD and lightning surge immunity.
Technical Context
The SA60CA-E3/54 operates as a silicon avalanche diode with glass-passivated junction, enabling symmetrical clamping in both polarities. Its bidirectional architecture eliminates polarity marking and supports AC-coupled lines without orientation constraints. The device responds in <1 ps to transients and maintains stable VBR over temperature via a +71 mV/°C coefficient.
It delivers 500 W peak pulse power under standardized 10/1000 μs waveform with 0.01% duty cycle, and sustains 3.0 W steady-state power at TL = 75 °C. Thermal derating begins above 25 °C ambient, and maximum junction temperature is rated at 175 °C - critical for under-hood automotive deployments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before clamping initiates; defines safe working range for protected circuitry. |
| VBR (min/max) | 66.7 V / 73.7 V at IT = 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | ≤96.8 V at 5.2 A - Clamped voltage under full-rated transient; determines worst-case stress on downstream components. |
| PPPM | 500 W (10/1000 μs) - Surge energy handling capacity; validates protection against IEC 61000-4-5 Level 4 surges. |
| ID @ VWM | ≤1.0 μA - Reverse leakage at stand-off voltage; ensures minimal quiescent power loss and signal integrity. |
| TJ max. | +175 °C - Maximum junction temperature rating; enables use in high-ambient environments like engine control units. |
| AEC-Q101 | Qualified - Certified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22. |
Pinout & Package
SA60CA-E3/54 is housed in DO-15 (DO-204AC) axial-leaded package: molded epoxy body, matte tin-plated leads solderable per J-STD-002, UL 94 V-0 rated compound, and no polarity marking (bidirectional).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (unmarked ends) | Bidirectional avalanche junction terminals | Electrically symmetric; either lead may connect to line or ground - simplifies PCB layout and eliminates orientation checks. |
Key Features

| 500 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 4th-level surge immunity (4 kV line-earth, 2 kV line-line) in compact DO-15 form factor. |
| AEC-Q101 qualified | Validated for automotive applications including powertrain, body electronics, and ADAS sensor interfaces. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ISO 7637-2 pulse 1/2a/5a), improving system-level robustness. |
| Solder dip 275 °C max. (10 s) | Compatible with standard wave-soldering processes without parametric shift or bond wire damage. |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting LIN bus or 12 V supply rails in door modules and lighting ECUs from load dump and inductive switching spikes. IC Role / Device Role: Bidirectional clamping element placed between power rail and chassis ground. Use Value: Limits transient voltage to ≤96.8 V, preventing latch-up or gate oxide damage in connected MCUs and drivers. |

IC Role / Device Role: Low-capacitance TVS across differential signal pair (e.g., 4–20 mA loop) and ground. Use Value: Sub-1 μA leakage at 60 V preserves signal accuracy; bidirectional symmetry avoids polarity-dependent failure modes. |
| Telecom DC Power Input Protection | Consumer Appliance Motor Drive Protection |

Use Value: 500 W rating handles repeated 10/1000 μs surges per IEC 61000-4-5; DO-15 footprint allows easy retrofit into legacy designs. |
Use Scenario: Suppressing commutation spikes from brushed DC motors in washing machines and HVAC blowers. IC Role / Device Role: Across motor terminals to clamp inductive kickback during PWM switching. Use Value: 175 °C TJ rating withstands enclosure temperatures >105 °C; AEC-Q101 qualification ensures longevity in high-vibration environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA60CA | Same VWM/VBR/PPPM specs but in smaller SMA (DO-214AC) surface-mount package; 1.5 A lower IPPM (3.7 A vs. 5.2 A). | Preferred for space-constrained PCBs where reflow assembly is used; unsuitable for through-hole or high-current leaded layouts. | Select SMA60CA only when board real estate is critical and peak surge current remains below 3.7 A. |
| 1.5KE60CA | Higher PPPM (1500 W), larger DO-201AD package, same VWM/VBR; 10× higher IPPM (23.3 A), but not AEC-Q101 qualified. | Used in industrial mains-input protection where automotive qualification is unnecessary and surge energy exceeds 500 W. | Choose 1.5KE60CA for non-automotive, high-energy surge scenarios - avoid where AEC-Q101 compliance or DO-15 footprint is mandatory. |
Compared with SMA60CA and 1.5KE60CA, SA60CA-E3/54 uniquely balances AEC-Q101 qualification, DO-15 through-hole compatibility, and 500 W surge rating - making it optimal for automotive and industrial control boards requiring proven reliability and serviceability.

FAQ
What is the clamping voltage of SA60CA-E3/54 under full-rated surge current?
The SA60CA-E3/54 clamps to a maximum of 96.8 V when subjected to its rated peak pulse current of 5.2 A (10/1000 μs waveform). This value is measured per Figure 9 in the official Vishay datasheet (Doc. #88378) and defines the upper voltage limit imposed on protected circuitry during transient events.
Is SA60CA-E3/54 suitable for automotive applications?
Yes, SA60CA-E3/54 is AEC-Q101 qualified per the Vishay datasheet revision dated 27-Sep-2021. It has passed stress tests including high-temperature reverse bias, temperature cycling, and ESD, making it appropriate for under-hood and body electronics applications where reliability under thermal and electrical stress is critical.
Does SA60CA-E3/54 have polarity markings?
No, SA60CA-E3/54 is a bidirectional TVS diode and carries no polarity marking on its DO-15 package. Both leads are functionally identical - the device clamps symmetrically in either direction, eliminating orientation concerns during manual or automated assembly.
What is the maximum junction temperature rating for SA60CA-E3/54?
The SA60CA-E3/54 has a maximum junction temperature (TJ max.) of +175 °C, as specified in the "Maximum Ratings" table of the Vishay datasheet. This rating supports operation in high-ambient environments such as engine compartments or enclosed industrial enclosures without thermal derating penalties up to that limit.
How does SA60CA-E3/54 differ from unidirectional SA60A-E3/54?
SA60CA-E3/54 is bidirectional with symmetrical clamping in both directions and no cathode band, while SA60A-E3/54 is unidirectional with a cathode marking and conducts forward current only. Their VWM, VBR, and PPPM ratings are identical, but SA60A-E3/54 exhibits forward voltage drop (~3.5 V at 100 A) and is unsuitable for AC or floating-line protection where polarity reversal occurs.
