SAC5.0-TP Transient Voltage Suppressor (TVS) Diode - Equivalent & Substitute Parts

Part Overview

The SAC5.0-TP is a unidirectional Zener-type transient voltage suppressor manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection applications. This through-hole component operates across a temperature range of -55°C to 175°C and is ROHS3 compliant with unlimited moisture sensitivity rating. The part is currently active in production with 1023 units in stock. Equivalent and substitute parts are identified based on matching electrical performance characteristics and mechanical compatibility within the DO-15 package family.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SAC5.0-TP is determined by the following critical parameters:

Primary Matching Criteria:

• Voltage - Reverse Standoff (Typ): 5V
• Voltage - Clamping (Max) @ Ipp: 10V maximum
• Current - Peak Pulse (10/1000µs): minimum 44A
• Package / Case: DO-204AC or DO-15 (axial through-hole)
• Mounting Type: Through Hole
• Type: Zener, Unidirectional (1 channel)
• RoHS Status: ROHS3 Compliant

Acceptable Variation Range:

• Voltage - Breakdown (Min): 6.4V to 7.6V
• Voltage - Clamping (Max) @ Ipp: up to 10V
• Current - Peak Pulse: 44A or greater
• Power - Peak Pulse: 500W minimum
• Operating Temperature: -55°C to 175°C or wider

Parts meeting these criteria are classified as direct equivalents or functionally compatible substitutes for general-purpose transient voltage suppression applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Identical Electrical Performance):

SAC5.0 (Littelfuse Inc.) and SAC5.0-E3/54 (Vishay General Semiconductor - Diodes Division) are direct equivalents to the SAC5.0-TP. Both parts maintain identical voltage ratings (5V reverse standoff, 7.6V breakdown minimum, 10V clamping maximum) and current specifications (44A peak pulse). All three parts are ROHS3 compliant, carry unlimited MSL ratings, and operate across the full -55°C to 175°C temperature range. These parts are suitable for one-to-one replacement in existing designs.

Functionally Compatible Substitutes (Enhanced Performance):

SA5.0A (Taiwan Semiconductor Corporation) and SA5.0A-B (Littelfuse Inc.) are functionally compatible substitutes with improved current handling. Both parts maintain the 5V reverse standoff specification but feature lower breakdown voltage (6.4V minimum) and lower clamping voltage (9.2V maximum). Peak pulse current ratings are higher at 57A and 55.4A respectively, providing enhanced transient suppression capability. These parts are suitable for applications where improved current capacity is beneficial and the lower clamping voltage is acceptable.

All substitute parts are active products with ROHS3 compliance and unlimited moisture sensitivity ratings, ensuring long-term availability and environmental compliance equivalent to the main part.

Frequently Asked Questions (FAQ)

Q: Can SAC5.0 (Littelfuse) be used as a direct replacement for SAC5.0-TP?

A: Yes. SAC5.0 is a direct equivalent with identical electrical specifications: 5V reverse standoff, 7.6V breakdown minimum, 10V clamping maximum, and 44A peak pulse current. Both parts use the DO-15 package and are ROHS3 compliant. The primary difference is packaging format (Tape & Reel for SAC5.0-TP versus Cut Tape for SAC5.0).

Q: What is the difference between SAC5.0-E3/54 and SAC5.0-TP?

A: SAC5.0-E3/54 (Vishay) and SAC5.0-TP are electrically identical with matching voltage and current ratings. Both are unidirectional Zener TVS diodes in DO-15 packages. The designation suffix indicates different manufacturer series and packaging specifications, but electrical performance is equivalent.

Q: Can SA5.0A be substituted for SAC5.0-TP?

A: SA5.0A is a functionally compatible substitute with enhanced current capacity (57A versus 44A). The 5V reverse standoff voltage matches, but breakdown voltage is lower (6.4V minimum versus 7.6V) and clamping voltage is lower (9.2V maximum versus 10V). This part is suitable when improved current handling is required and the lower clamping voltage is acceptable for the application.

Q: Are all substitute parts available in the same package?

A: All substitute parts use the DO-204AC or DO-15 axial through-hole package, ensuring mechanical compatibility. Packaging format (Tape & Reel, Cut Tape, or Bulk) varies by manufacturer and supplier, but the physical component package remains identical.

Q: What compliance certifications apply to all listed parts?

A: All parts listed are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1). All parts are REACH unaffected and carry EAR99 export classification. All parts operate across the -55°C to 175°C temperature range.

Q: Which substitute part offers the best current handling?

A: SA5.0A provides the highest peak pulse current rating at 57A, followed by SA5.0A-B at 55.4A. Both exceed the SAC5.0-TP specification of 44A. Selection should be based on application requirements and acceptable clamping voltage limits.
