Product details
Overview
SA58CA-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 58 V standoff voltage (VWM), 64.4–71.2 V breakdown voltage (VBR) at 1 mA, 500 W peak pulse power (10/1000 μs), 93.6 V maximum clamping voltage at 5.3 A, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SA58CA-E3/54 datasheet, SA58CA-E3/54 pinout, SA58CA-E3/54 application, or SA58CA-E3/54 equivalent, this page provides verified electrical parameters, clamping behavior under surge conditions, DO-15 mechanical interface details, automotive-grade reliability data, and direct alternatives for circuit protection design.
Technical Context
The SA58CA-E3/54 operates as a bidirectional avalanche diode, symmetrically clamping transient overvoltages in both polarities without polarity marking. Its silicon junction is glass passivated for stable leakage and long-term reliability, with low incremental surge resistance enabling effective energy diversion during 10/1000 μs surges up to 5.3 A.
It delivers 500 W peak pulse power per IEC 61000-4-5 and ANSI/IEEE C62.35 standards, with thermal derating above 25 °C and operation across -55 °C to +175 °C junction temperature. The device meets JESD 22-B106 solderability and JESD 201 class 1A whisker resistance requirements.

Applications
| Automotive Power Line Protection | Industrial Sensor Interface |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump (ISO 7637-2 Pulse 5a) and alternator transients. IC Role / Device Role: Primary clamping element placed upstream of LDOs and microcontrollers.

IC Role / Device Role: Bidirectional shunt protector on transmitter output node. Use Value: Sub-μA leakage at 58 V avoids signal offset; symmetrical clamping preserves DC accuracy during ±8 kV contact ESD events. |

IC Role / Device Role: Standoff-rated protector between USB connector and power management IC. Use Value: 58 V VWM exceeds USB 2.0 spec (5.25 V) by wide margin, allowing use on 12 V auxiliary power rails without false triggering. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ58CA | Same VWM (58 V), lower PPPM (400 W), SMA package (smaller footprint, lower thermal mass) | Preferred for space-constrained PCBs; reduced surge margin requires verification against IEC 61000-4-5 Level 2. | Select SMAJ58CA when board area is critical and peak surge energy is ≤400 W. |
| 1.5KE58CA | Same VWM and PPPM (500 W), but DO-201 package (larger body, higher thermal inertia) | Better sustained surge handling in high-temperature ambient; less suitable for dense automotive modules. | Choose 1.5KE58CA for industrial power supplies where thermal cycling stability outweighs size constraints. |
Compared with SMAJ58CA and 1.5KE58CA, the SA58CA-E3/54 offers balanced surge capability and automotive qualification in the widely adopted DO-15 form factor-making it optimal for cost-sensitive, volume automotive and industrial designs requiring proven field reliability.

FAQ
What is the clamping voltage of the SA58CA-E3/54 under maximum rated surge current?
The SA58CA-E3/54 exhibits a maximum clamping voltage (VC) of 93.6 V when subjected to its peak pulse current (IPPM) of 5.3 A under a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. The SA58CA-E3/54 maintains this clamping performance across its qualified temperature range.
Is the SA58CA-E3/54 suitable for automotive applications?
Yes, the SA58CA-E3/54 is AEC-Q101 qualified, having passed stress tests including high-temperature operating life (HTOL), temperature cycling (TCT), and electrostatic discharge (HBM/MM). Its DO-15 package, 175 °C maximum junction temperature, and stable leakage below 1.0 μA at 58 V make the SA58CA-E3/54 appropriate for engine control units, body electronics, and infotainment power rails.
How does the bidirectional nature of the SA58CA-E3/54 affect its PCB layout?
The SA58CA-E3/54 has no polarity marking and functions identically in either orientation, simplifying layout and eliminating risk of reverse installation. Engineers may place the SA58CA-E3/54 across any two nodes requiring symmetrical overvoltage protection-such as differential signal pairs or AC-coupled power rails-without regard to anode/cathode assignment.
What is the maximum steady-state power dissipation for the SA58CA-E3/54?
The SA58CA-E3/54 has a maximum steady-state power dissipation (PD) of 3.0 W when mounted on an infinite heatsink at lead temperature (TL) = 75 °C. At room temperature, derating applies per Figure 5 in the datasheet; actual usable power depends on PCB copper area, airflow, and ambient conditions. This rating governs continuous leakage-related heating-not transient surge duty.
Does the SA58CA-E3/54 meet RoHS and lead-free assembly requirements?
Yes, the SA58CA-E3/54 carries the "E3" suffix, indicating RoHS compliance and qualification to JESD 201 class 1A whisker resistance. Its matte tin-plated leads are solderable per J-STD-002 and withstand solder dip at 275 °C for up to 10 seconds, supporting both wave and reflow processes in lead-free manufacturing environments.
