Product details
Overview
SA58CAHE3/54 from Vishay 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 stand-off voltage (VWM), 64.4–71.2 V breakdown voltage (VBR) at 1 mA, 500 W peak pulse power (10/1000 µs), 93.6 V max clamping voltage at 5.3 A, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SA58CAHE3/54 datasheet, SA58CAHE3/54 pinout, SA58CAHE3/54 application, or SA58CAHE3/54 equivalent, this device is selected for robust ESD and surge protection in automotive sensor interfaces, industrial I/O lines, and telecom line cards where bidirectional clamping, low leakage (<1 µA at 58 V), and high-temperature operation (−55 °C to +175 °C) are required.
Technical Context
The SA58CAHE3/54 operates as a symmetrical avalanche diode with identical forward and reverse breakdown characteristics, enabling bidirectional transient suppression without polarity sensitivity. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and low incremental surge resistance, critical for consistent clamping under repetitive surges.
It delivers 500 W peak pulse power per 10/1000 µs waveform at TA = 25 °C, derating linearly above 25 °C per Vishay's Fig. 2, and supports steady-state dissipation of 3.0 W on an infinite heatsink at TL = 75 °C. The device meets JESD22-B106 solderability (275 °C, 10 s) and JESD201 Class 2 whisker resistance (HE3 suffix).
Key Specifications
| Parameter | Value and Actual Design Meaning |

| VWM | 58 V - Maximum continuous reverse voltage before clamping begins; sets operating margin for 48 V automotive or 48 V PoE systems. |
| VBR (min/max) | 64.4 V / 71.2 V at 1 mA - Confirmed breakdown range ensures reliable turn-on within ±5 % tolerance for predictable protection threshold. |
| VC @ IPPM | 93.6 V at 5.3 A - Clamping voltage during full-rated 500 W surge; limits downstream voltage stress to safe levels for 75 V-rated ICs. |
| IPPM | 5.3 A - Peak pulse current capability with 10/1000 µs waveform; defines maximum surge energy the device can absorb without failure. |
| PPPM | 500 W - Peak pulse power rating per standard 10/1000 µs waveform; enables compliance with IEC 61000-4-5 Level 3 (1 kV/2 Ω) testing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58CA | DO-214AA package (SMB), 5.0 mm × 4.6 mm footprint; same VWM/VBR/PPPM, but lower IPPM (5.0 A vs. 5.3 A) and higher thermal resistance. | Surface-mount alternative for space-constrained PCBs; less suitable for high-vibration environments due to SMT mechanical retention. | Select SMBJ58CA when board area is limited and reflow compatibility is required; verify mechanical shock survivability in automotive mounting. |
| 1.5KE58CA | DO-201AD package; 1500 W PPPM, higher VC (96.0 V), larger size (7.1 mm × 5.3 mm); not AEC-Q101 qualified. | Higher-energy surge handling for AC mains or heavy industrial equipment; lacks automotive qualification and tighter VBR tolerance. | Choose 1.5KE58CA only for non-automotive, high-energy applications where 1500 W rating outweighs footprint and qualification needs. |
Compared with SMBJ58CA and 1.5KE58CA, the SA58CAHE3/54 offers optimal balance of AEC-Q101 qualification, axial-leaded mechanical robustness, and precise 58 V clamping margin - making it preferred for automotive and industrial field-deployed systems requiring long-term reliability and vibration resistance.

FAQ
What is the exact breakdown voltage range for SA58CAHE3/54?
The SA58CAHE3/54 has a minimum breakdown voltage (VBR) of 64.4 V and a maximum of 71.2 V at 1 mA test current, per Vishay Document 88378 Rev. 27-Sep-2021. This ±5 % tolerance ensures predictable clamping onset and is confirmed for the CA (bidirectional) variant. The SA58CAHE3/54 must be used within this specified VBR window for compliant surge protection design.
Is SA58CAHE3/54 suitable for automotive applications?
Yes, SA58CAHE3/54 is AEC-Q101 qualified (HE3 suffix), tested per stress requirements for automotive electronics including temperature cycling, humidity bias, and mechanical shock. Its −55 °C to +175 °C operating range, glass-passivated junction, and DO-15 mechanical robustness make SA58CAHE3/54 appropriate for under-hood and chassis-mounted automotive modules.
What does the "HE3/54" suffix mean in SA58CAHE3/54?
The "HE3" denotes RoHS-compliant construction with JESD201 Class 2 whisker resistance and AEC-Q101 qualification; "54" specifies the preferred package code for 13-inch paper tape and reel packaging with 4000 units per reel. This ordering code ensures traceable, automotive-grade SA58CAHE3/54 delivery aligned with Vishay's standardized logistics protocol.
How does SA58CAHE3/54 compare to unidirectional SA58A variants?
SA58CAHE3/54 is bidirectional with symmetrical clamping in both polarities and no cathode marking, whereas SA58A is unidirectional with a cathode band and forward conduction capability. SA58CAHE3/54 cannot replace SA58A in DC-biased circuits requiring forward rectification, but is superior for AC-coupled or differential signal lines like CAN or telecom pairs where polarity is undefined.
What is the maximum clamping voltage of SA58CAHE3/54 during a 500 W surge?
The maximum clamping voltage (VC) of SA58CAHE3/54 is 93.6 V at its rated peak pulse current of 5.3 A (10/1000 µs waveform), per Vishay's electrical characteristics table. This value defines the upper voltage limit imposed on protected circuitry during worst-case surge events and is guaranteed across the full operating temperature range.
