SA30A-TP Equivalent & Substitute Parts

Part Overview

The SA30A-TP is a unidirectional Zener-type Transient Voltage Suppressor (TVS) diode designed for general-purpose transient protection applications. Manufactured by Micro Commercial Co, this through-hole component operates across a temperature range of -55°C to 175°C and is currently in active production status. The SA30A-TP is specified for applications requiring 30V reverse standoff voltage protection with a 500W peak pulse power rating. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SA30A-TP is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): Must be 30V to maintain circuit protection threshold
• Voltage - Breakdown (Min): Must be 33.3V minimum to ensure consistent trigger behavior
• Mounting Type: Must be Through Hole to maintain PCB assembly compatibility
• Package / Case: Must support DO-204AC or DO-15 axial configuration for mechanical fit
• Type: Must be Zener-type unidirectional TVS diode
• Unidirectional Channels: Must be 1 channel
• Operating Temperature Range: Must support -55°C to 175°C minimum
• Power - Peak Pulse: Must be 500W or greater

The SA30A substitute part meets all critical substitution criteria while maintaining functional equivalence within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the SA30A-TP and SA30A substitute part maintain active product status with full RoHS3 and REACH compliance. Selection between these components should be based on availability and packaging requirements. The SA30A is supplied in Tape & Reel (TR) packaging with significantly higher inventory availability (45,100 pcs), while the SA30A-TP is supplied in Cut Tape (CT) packaging. Both components share identical reverse standoff voltage, breakdown voltage, operating temperature range, and peak pulse power specifications. The SA30A exhibits marginally higher clamping voltage (64.3V vs 48.4V) and peak pulse current (10.8A vs 10.5A), which remain within acceptable substitution parameters for general-purpose transient protection applications.

Frequently Asked Questions (FAQ)

Q: Can the SA30A substitute for the SA30A-TP in all applications?

A: Yes, the SA30A meets all critical electrical and mechanical substitution criteria. Both components share identical reverse standoff voltage (30V), breakdown voltage (33.3V minimum), operating temperature range (-55°C to 175°C), and peak pulse power (500W). Both are Zener-type unidirectional TVS diodes in DO-15/DO-204AC axial through-hole packages.

Q: What is the difference in clamping voltage between these parts?

A: The SA30A-TP specifies a maximum clamping voltage of 48.4V at peak pulse current, while the SA30A specifies 64.3V. Both values are within acceptable operating parameters for 30V standoff voltage protection circuits.

Q: Are there packaging differences between SA30A-TP and SA30A?

A: Yes. The SA30A-TP is supplied in Cut Tape (CT) packaging, while the SA30A is supplied in Tape & Reel (TR) packaging. Both use identical DO-15/DO-204AC axial through-hole package configurations and are mechanically interchangeable on PCBs.

Q: Do both parts meet regulatory compliance requirements?

A: Yes. Both the SA30A-TP and SA30A are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.

Q: What is the peak pulse current difference?

A: The SA30A-TP is rated for 10.5A peak pulse current (10/1000µs), while the SA30A is rated for 10.8A. This minor difference does not affect substitution eligibility for general-purpose transient protection applications.
