SMAJ60C Equivalent & Substitute Parts
Part Overview
The SMAJ60C is a transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection in surface-mount applications. This component features a 60V reverse standoff voltage, 101.64V maximum clamping voltage, and 4.1A peak pulse current capability in a DO-214AC (SMA) package. The SMAJ60C is classified as obsolete, necessitating identification of active equivalent and substitute parts that maintain electrical and mechanical compatibility for ongoing production and repair applications.

Substitute Part Grouping Explanation
Substitute parts for the SMAJ60C are grouped based on strict electrical parameter compatibility within the TVS diode category. The primary substitution criteria are:
Critical Parameters for Substitution:
- Reverse standoff voltage: 60V (all substitutes maintain this specification)
- Package / Case: DO-214AC, SMA (all substitutes use identical package)
- Mounting type: Surface Mount (all substitutes are surface-mount compatible)
- Bidirectional channels: 1 (all substitutes are single-channel devices)
- Type: Zener (all substitutes are Zener-type TVS diodes)
- RoHS Status: ROHS3 Compliant (all substitutes meet this compliance requirement)
- Moisture Sensitivity Level: 1 (Unlimited) (all substitutes match this specification)
Allowable Parameter Variations: Substitute parts may vary in clamping voltage (96.8V to 107V range), peak pulse current (4.1A to 5.2A), peak pulse power (400W to 500W), and operating temperature ranges, provided these variations remain within the functional requirements of the application circuit. Manufacturer and product status may differ, with active substitutes preferred over obsolete parts.

Engineering Selection Recommendations
All listed substitute parts are active products with ROHS3 compliance and MSL 1 (Unlimited) ratings, making them suitable for production environments. The SMAJ60CA-TP (Micro Commercial Co) offers the widest operating temperature range (-55°C to 175°C), providing flexibility for extended thermal applications. The SMAJ60CAE3/TR13 and SMAJ60CE3/TR13 (Microchip Technology) provide enhanced peak pulse power ratings (500W) compared to the original 400W specification, offering additional margin for transient protection. SMAJ60CA (MDD) and TV04A600JB-G / TV04A600JB-HF (Comchip Technology) maintain electrical parameters closely aligned with the original SMAJ60C specifications. Selection should prioritize availability, packaging format requirements, and thermal operating range compatibility with the target application.
Frequently Asked Questions (FAQ)
Q: Can SMAJ60CA be used as a direct replacement for SMAJ60C? A: Yes. SMAJ60CA maintains the same 60V reverse standoff voltage, DO-214AC (SMA) package, and equivalent peak pulse current (4.1A). The clamping voltage is 96.8V compared to the original 101.64V, which is within acceptable substitution parameters for general-purpose TVS applications.
Q: What is the difference between SMAJ60CAE3/TR13 and SMAJ60CE3/TR13? A: Both are Microchip Technology products with identical electrical specifications except for clamping voltage. SMAJ60CAE3/TR13 clamps at 96.8V with 5.2A peak pulse current and 500W power rating. SMAJ60CE3/TR13 clamps at 107V with 4.7A peak pulse current and 500W power rating. Selection depends on the specific clamping voltage requirement of the circuit.
Q: Are all substitute parts available in Tape & Reel packaging? A: Most substitutes are available in Tape & Reel (TR) format. SMAJ60CA (MDD) does not specify packaging format in the provided data. SMAJ60CA-13-F (Diodes Incorporated) is available in Cut Tape (CT) and Digi-Reel® formats. Verify packaging availability with the supplier for production requirements.
Q: What is the temperature range difference between SMAJ60CA-TP and other substitutes? A: SMAJ60CA-TP (Micro Commercial Co) operates from -55°C to 175°C (TA), providing a 25°C higher maximum temperature compared to most other substitutes which operate to 150°C (TJ). This extended range is beneficial for high-temperature applications.
Q: Do all substitute parts meet RoHS3 compliance? A: Yes. All listed substitute parts are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity ratings, meeting current environmental and reliability standards for electronic component manufacturing.
Q: Can TV04A600JB-G and TV04A600JB-HF be used interchangeably? A: Yes. Both Comchip Technology parts are electrically identical with 60V reverse standoff, 96.8V clamping voltage, and 4.13A peak pulse current. The suffix difference (-G versus -HF) indicates different packaging or lead finish specifications but does not affect electrical performance.
