Equivalent & Substitute Parts for SA16C-E3/73 Transient Voltage Suppressors (TVS)

Part Overview

The Vishay General Semiconductor SA16C-E3/73 is a TransZorb® transient voltage suppressor (TVS) diode designed for general-purpose overvoltage protection applications. This through-hole TVS diode features a 16V reverse standoff voltage, 28.8V maximum clamping voltage at a peak pulse current of 17.4A, and is housed in the DO-204AC (DO-15) axial package. The product is currently classified as obsolete, necessitating the identification of alternate models with matching electrical and mechanical specifications for continued maintenance and design compatibility within existing systems.

Engineering Selection Recommendations

Given the obsolete status of SA16C-E3/73, suitable substitutes include SA16CA (Taiwan Semiconductor Corporation) and SA16CA-TP (Micro Commercial Co). Both substitutes are compliant with ROHS3, REACH, and have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), ensuring equivalent handling and regulatory status. Both substitutes provide compatible mechanical packages and supplier device formats, supporting drop-in replacement in the DO-204AC (DO-15) through-hole category.

Frequently Asked Questions (FAQ)

Q1: What are the primary parameters for selecting substitutes for SA16C-E3/73?
A1: Selection is based on matching type, bidirectional channel count, reverse standoff voltage, breakdown voltage, clamping voltage at peak pulse current, peak pulse current, power rating, operating temperature range, and mechanical package. Compliance parameters such as RoHS, REACH, and MSL are also considered.

Q2: Are the recommended substitutes in the same package as SA16C-E3/73?
A2: Yes, all listed substitutes use the DO-204AC (DO-15) axial through-hole package, ensuring mechanical compatibility.

Q3: How do substitute TVS diodes compare in electrical performance?
A3: Substitute diodes SA16CA and SA16CA-TP maintain the same reverse standoff and breakdown voltage, with clamping voltages and peak pulse currents that support the intended protection functions in general-purpose applications.

Q4: What compliance standards do substitutes meet?
A4: All substitutes meet ROHS3 compliance, REACH unaffected status, MSL 1 (Unlimited), ECCN EAR99, and HTSUS 8541.10.0080 requirements.
