SMAJ60CE3/TR13 Equivalent & Substitute Parts

Part Overview

The SMAJ60CE3/TR13 is a transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection in surface-mount applications. This bidirectional Zener diode operates with a 60V reverse standoff voltage and provides peak pulse current handling of 4.7A with a maximum clamping voltage of 107V. The component is packaged in DO-214AC (SMA) format and is currently in active production status with RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are necessary when the original SMAJ60CE3/TR13 is unavailable due to inventory constraints, supply chain disruptions, or when alternative manufacturers' versions meet the electrical and mechanical requirements of the application.

Substitute Part Grouping Explanation

Substitution of the SMAJ60CE3/TR13 is determined by strict electrical and mechanical compatibility criteria. All substitute parts must meet the following requirements:

Critical Matching Parameters:

Voltage - Reverse Standoff (Typ): 60V
Voltage - Breakdown (Min): 66.7V
Package / Case: DO-214AC, SMA
Mounting Type: Surface Mount
Type: Zener
Bidirectional Channels: 1
RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

Voltage - Clamping (Max) @ Ipp: Substitute parts may have lower clamping voltage (96.8V vs. 107V) provided the application does not require the higher clamping specification
Current - Peak Pulse (10/1000µs): Substitute parts may have lower peak pulse current (4.1A vs. 4.7A) provided the application does not require the higher current specification
Power - Peak Pulse: Substitute parts may have lower peak pulse power (400W vs. 500W) as a consequence of lower current rating
Operating Temperature Range: Substitute parts may have different temperature ranges provided the application operates within the substitute part's specified range

All substitute parts listed are active products with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Engineering Selection Recommendations

All listed substitute parts are active products with ROHS3 compliance and unlimited moisture sensitivity rating, making them suitable for direct substitution in applications where the electrical parameter variations are acceptable.

SMAJ60CA (MDD): This substitute offers identical voltage specifications and is available in high inventory (17,241 pcs). The reduced peak pulse current (4.1A vs. 4.7A) and clamping voltage (96.8V vs. 107V) are acceptable for applications not requiring the higher specifications of the original part. Operating temperature range is -50 to 150°C.

SMAJ60CA-13-F (Diodes Incorporated): This substitute provides the same electrical characteristics as the MDD variant with 1,900 pcs in stock. Packaging is Cut Tape (CT) & Digi-Reel® format. Operating temperature range is -55 to 150°C, providing slightly lower minimum temperature coverage than the original part.

SMAJ60CA-E3/61 (Vishay General Semiconductor - Diodes Division): This substitute is part of the TransZorb® series and offers the same electrical characteristics as other SMAJ60CA variants. High inventory availability (36,400 pcs) and Tape & Reel packaging support production requirements. Operating temperature range is -55 to 150°C.

SMAJ60CA-TP (Micro Commercial Co): This substitute provides the widest operating temperature range (-55 to 175°C) and the highest inventory availability (104,544 pcs). Electrical characteristics match other SMAJ60CA variants. Tape & Reel packaging is standard.

Selection among substitute parts should be based on inventory availability, packaging format requirements, temperature range requirements, and lead time considerations. All parts are electrically compatible for applications where the reduced peak pulse current and clamping voltage specifications are acceptable.

Frequently Asked Questions (FAQ)

Q: Can SMAJ60CA variants be used as direct replacements for SMAJ60CE3/TR13?

A: SMAJ60CA variants are electrically compatible substitutes provided the application does not require the higher peak pulse current (4.7A) or clamping voltage (107V) specifications of the original part. All variants maintain the critical 60V reverse standoff voltage and 66.7V minimum breakdown voltage. Package and mounting specifications are identical.

Q: What is the difference between the clamping voltage specifications?

A: The SMAJ60CE3/TR13 has a maximum clamping voltage of 107V, while all SMAJ60CA variants have a maximum clamping voltage of 96.8V. This 10.2V difference represents the maximum voltage the diode will clamp transient events to at peak pulse current. Applications requiring the lower clamping voltage of the SMAJ60CA variants will experience slightly higher voltage suppression performance.

Q: Are there packaging differences between substitute parts?

A: All substitute parts use the DO-214AC (SMA) package for surface-mount applications. Packaging format variations exist: SMAJ60CA (MDD) and SMAJ60CA-E3/61 (Vishay) are supplied in Tape & Reel (TR) format; SMAJ60CA-13-F (Diodes Incorporated) is supplied in Cut Tape (CT) & Digi-Reel® format; SMAJ60CA-TP (Micro Commercial Co) is supplied in Tape & Reel (TR) format. Select based on assembly equipment compatibility.

Q: What are the operating temperature range differences?

A: The original SMAJ60CE3/TR13 operates from -65°C to 150°C (TJ). Substitute parts have narrower minimum temperature specifications: SMAJ60CA (MDD) operates from -50°C to 150°C; SMAJ60CA-13-F (Diodes Incorporated) operates from -55°C to 150°C; SMAJ60CA-E3/61 (Vishay) operates from -55°C to 150°C; SMAJ60CA-TP (Micro Commercial Co) operates from -55°C to 175°C (TA). Select based on application temperature requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), matching the compliance status of the original SMAJ60CE3/TR13.

Q: What is the peak pulse current difference between the original and substitute parts?

A: The SMAJ60CE3/TR13 handles 4.7A peak pulse current, while all SMAJ60CA variants handle 4.1A peak pulse current. This 0.6A difference represents a 13% reduction in peak pulse current capability. Applications with transient events exceeding 4.1A peak current require the original part specification.

Q: Which substitute part has the best inventory availability?

A: SMAJ60CA-TP (Micro Commercial Co) has the highest inventory availability with 104,544 pcs in stock, followed by SMAJ60CA-E3/61 (Vishay) with 36,400 pcs, SMAJ60CA (MDD) with 17,241 pcs, and SMAJ60CA-13-F (Diodes Incorporated) with 1,900 pcs.
