Product details
Overview
SA13CA-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 500 W peak pulse power (10/1000 μs), 14.4 V to 15.9 V breakdown voltage at 1 mA, 13 V stand-off voltage, <1 μA reverse leakage at VWM, and clamps to ≤21.5 V at 23.3 A peak pulse current.
For engineers reviewing the SA13CA-E3/54 datasheet, SA13CA-E3/54 pinout, SA13CA-E3/54 application, or SA13CA-E3/54 equivalent, this device is selected for robust ESD and surge protection in automotive sensor interfaces, industrial I/O modules, and telecom line drivers where bidirectional clamping and AEC-Q101 qualification are required.
Technical Context
The SA13CA-E3/54 operates as a bidirectional avalanche diode with symmetrical clamping in both polarities, enabling protection of AC-coupled or floating signal paths without polarity constraints. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and low incremental surge resistance, critical for consistent clamping under repetitive transients.
It is rated for -55 °C to +175 °C operating junction temperature, supports 70 A unidirectional IFSM (not applicable here due to bidirectional configuration), and meets JESD22-B106 solderability and JESD201 Class 1A whisker resistance standards via its matte tin-plated leads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse voltage before significant leakage; defines safe operating window for protected circuitry. |
| VBR (min/max) | 14.4 V / 15.9 V at 1 mA - Confirmed avalanche onset range; ensures reliable triggering above normal operating voltage. |
| ID @ VWM | <1 μA - Ultra-low leakage preserves signal integrity and minimizes standby power loss in high-impedance nodes. |
| VC @ IPPM | 21.5 V at 23.3 A - Clamped voltage during 10/1000 μs surge; determines maximum stress imposed on downstream ICs. |
| PPPM | 500 W - Peak transient energy absorption capability; sufficient for IEC 61000-4-5 Level 3 (1 kV/2 Ω) surges. |
| TJ max | +175 °C - High junction temperature rating enables use in under-hood automotive or enclosed industrial environments. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard. |
Pinout & Package
DO-15 (DO-204AC) molded epoxy package with axial leads; no polarity marking (bidirectional configuration). Body diameter: 0.130–0.138 inch (3.3–3.5 mm); lead length ≥1.0 inch (25.4 mm); weight: 0.432 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | No functional distinction between leads; either terminal serves as clamping path for positive or negative transients. |
| Lead 1 | External connection point | Matte tin-plated, solderable per J-STD-002; withstands 275 °C for 10 s per JESD22-B106. |
| Lead 2 | External connection point | Identical to Lead 1; enables PCB layout flexibility with no orientation dependency. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR over time and temperature, minimizing parameter drift in long-life industrial deployments. |
| 500 W peak pulse power (10/1000 μs) | Handles high-energy transients such as inductive switch-off spikes in solenoid drivers or relay coils. |
| AEC-Q101 qualification | Validates suitability for automotive applications including body control modules and sensor front-ends. |
| UL 94 V-0 molding compound | Provides flame-retardant housing essential for safety-critical industrial and transportation equipment. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage exposure to protected ICs-critical for 3.3 V or 5 V logic interfacing. |
Applications
| Automotive Sensor Interface | Industrial PLC Analog Input |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and Hall-effect sensor outputs from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional clamping element placed at connector entry point to shunt surge energy before it reaches signal conditioning circuitry. Use Value: Maintains signal fidelity under 12 V/24 V automotive supply conditions while surviving repeated 100 V/500 ms load dump events. | Use Scenario: Safeguarding 4–20 mA current loop inputs in programmable logic controllers against field wiring faults and electrostatic discharge. IC Role / Device Role / Timing Role: Primary overvoltage clamp on input terminals, operating in parallel with precision shunt regulators and op-amp front-ends. Use Value: Limits transient-induced offset errors and prevents latch-up in instrumentation amplifiers during factory floor ESD events. |
| Telecom Line Driver Protection | Consumer Appliance Motor Control |
Use Scenario: Shielding RS-485 transceivers and Ethernet PHYs from lightning-induced surges on outdoor cabling in security or building automation systems. IC Role / Device Role / Timing Role: First-line transient suppressor on differential pair traces, coordinated with common-mode chokes and GDTs. Use Value: Achieves IEC 61000-4-5 compliance up to 1 kV (2 Ω source) without degrading signal rise/fall times due to low capacitance (<100 pF). | Use Scenario: Guarding microcontroller GPIOs and gate drivers connected to brushed DC motor commutation circuits in washing machines or HVAC blowers. IC Role / Device Role / Timing Role: Fast-response clamp across motor coil flyback paths and MCU-level signal lines subject to inductive kickback.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13CA | Same VWM (13 V), identical DO-214AC package, but lower PPPM (400 W) and higher VC (21.5 V → 23.2 V at same IPPM). | Less suitable for high-energy surges like IEC 61000-4-5 Level 4; better for space-constrained SMT layouts. | Select SMAJ13CA only when board area is limited and surge threat level is ≤Level 3. |
| 1.5KE13CA | Higher PPPM (1500 W), larger DO-201AE package, same VWM/VBR specs, but slower response due to higher junction capacitance. | Preferred for mains-connected equipment requiring higher surge margin, not for high-speed signal lines. | Choose 1.5KE13CA when protecting AC power inputs or legacy industrial backplanes with less stringent speed requirements. |
Compared with SMAJ13CA and 1.5KE13CA, the SA13CA-E3/54 delivers optimal balance of 500 W surge handling, DO-15 through-hole compatibility, and low-clamp performance-making it ideal for cost-sensitive, high-reliability automotive and industrial PCBs where axial mounting and AEC-Q101 validation are mandatory.

FAQ
What is the breakdown voltage range of the SA13CA-E3/54?
The SA13CA-E3/54 has a minimum breakdown voltage (VBR) of 14.4 V and a maximum of 15.9 V at 1 mA test current, as specified in the Vishay datasheet document 88378. This tight tolerance ensures predictable clamping behavior across production lots and temperature ranges, directly supporting design margin calculations for protected circuits using the SA13CA-E3/54.
Is the SA13CA-E3/54 suitable for automotive applications?
Yes, the SA13CA-E3/54 is AEC-Q101 qualified per Vishay documentation, confirming its reliability for automotive use cases including engine control units, body electronics, and ADAS sensor interfaces. Its DO-15 package, -55 °C to +175 °C operating range, and validated surge performance make the SA13CA-E3/54 appropriate for under-hood and cabin-mounted systems.
Does the SA13CA-E3/54 have polarity markings?
No, the SA13CA-E3/54 is a bidirectional TVS diode and carries no polarity marking on its DO-15 package. Both leads are functionally identical, allowing unrestricted orientation during PCB assembly-a key advantage for automated placement and field-repair scenarios where the SA13CA-E3/54 is deployed.
What is the clamping voltage of the SA13CA-E3/54 at its rated peak pulse current?
At its rated peak pulse current of 23.3 A (10/1000 μs waveform), the SA13CA-E3/54 clamps to a maximum of 21.5 V. This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuitry during surge events, a critical parameter when selecting the SA13CA-E3/54 for 3.3 V or 5 V system interfaces.
Can the SA13CA-E3/54 replace unidirectional TVS diodes in existing designs?
No-the SA13CA-E3/54 is strictly bidirectional and cannot substitute for unidirectional TVS diodes (e.g., SA13A-E3/54) in DC-biased circuits where forward conduction must be blocked. Attempting to use the SA13CA-E3/54 in such configurations may cause excessive leakage or unintended conduction; always verify polarity requirements before specifying the SA13CA-E3/54.
