Substitute Part Grouping Explanation

Substitution of the SA58CA is determined by strict equivalence across the following electrical and mechanical parameters:

Voltage - Reverse Standoff (Typ): 58V
Voltage - Breakdown (Min): 64.4V
Voltage - Clamping (Max) @ Ipp: 93.6V
Current - Peak Pulse (10/1000µs): 5.3A minimum
Power - Peak Pulse: 500W
Type: Zener, single bidirectional channel
Mounting Type: Through Hole

Engineering Selection Recommendations

Primary Selection: SA58CA from Taiwan Semiconductor Corporation or SA58CA-E3/54 from Vishay General Semiconductor - Diodes Division. Both parts maintain active product status with full electrical equivalence and established supply availability.

Automotive Applications: SA58CAHE3/54 from Vishay General Semiconductor - Diodes Division is qualified to AEC-Q101 automotive standard and carries active product status, suitable for automotive-grade transient voltage suppression requirements.

Extended Temperature Range: P5KE58CA series (P5KE58CA-AP, P5KE58CA-BP, P5KE58CA-TP) from Micro Commercial Co provides -65°C to 175°C operating temperature range, exceeding standard -55°C to 175°C specifications.

Packaging Considerations: All substitute parts maintain DO-15 axial through-hole package compatibility. Taiwan Semiconductor Corporation and Vishay parts specify DO-204AC designation, which is equivalent to DO-15 in physical form factor.

Frequently Asked Questions (FAQ)

Q: Can SA58CA-E3/54 directly replace the obsolete onsemi SA58CA?

A: Yes. SA58CA-E3/54 meets all electrical specifications: 58V reverse standoff voltage, 64.4V minimum breakdown voltage, 93.6V maximum clamping voltage, and 5.3A peak pulse current. Physical package compatibility is maintained in DO-204AC (DO-15) axial configuration.

Q: What is the difference between SA58CA variants from different manufacturers?

A: Electrical specifications remain identical across manufacturers. Differences exist in peak pulse current ratings (5.3A vs 5.4A), operating temperature ranges (-55°C to 175°C vs -65°C to 175°C), and product status (active vs obsolete). All variants maintain 58V standoff and 93.6V clamping specifications.

Q: Are P5KE58CA and SA58CA parts interchangeable?

A: Yes, for general-purpose applications. Both series meet identical voltage and current specifications. P5KE58CA series provides extended lower temperature rating (-65°C vs -55°C minimum). Physical package remains DO-15 axial through-hole.

Q: Which substitute part is recommended for new automotive designs?

A: SA58CAHE3/54 from Vishay General Semiconductor - Diodes Division carries AEC-Q101 automotive qualification and active product status, meeting automotive-grade transient voltage suppression requirements.

Q: Do all substitute parts support the same 500W peak pulse power rating?

A: Yes. All listed substitute parts maintain 500W peak pulse power specification, ensuring thermal performance equivalence in transient suppression applications.

Q: What packaging options are available for SA58CA substitutes?

A: All substitute parts are supplied in DO-15 axial through-hole package configuration. Taiwan Semiconductor Corporation and Vishay parts specify DO-204AC designation, which is the standardized equivalent to DO-15.
