SMAJ60CA-13 Equivalent & Substitute Parts

Part Overview

The SMAJ60CA-13 is a transient voltage suppressor (TVS) diode manufactured by Diodes Incorporated, designed for general-purpose overvoltage protection in surface-mount applications. This component features a 60V reverse standoff voltage with a 96.8V maximum clamping voltage and 4.1A peak pulse current capability in a DO-214AC (SMA) package. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the SMAJ60CA-13 is determined by strict equivalence across the following critical parameters:

Voltage - Reverse Standoff (Typ): 60V
Voltage - Breakdown (Min): 66.7V
Voltage - Clamping (Max) @ Ipp: 96.8V
Current - Peak Pulse (10/1000µs): 4.1A
Power - Peak Pulse: 400W
Package / Case: DO-214AC, SMA
Mounting Type: Surface Mount
Bidirectional Channels: 1
Type: Zener

All identified substitutes maintain identical electrical specifications across these parameters. Variations in operating temperature range, RoHS compliance status, and packaging format (tape & reel, cut tape, or bulk) do not affect functional equivalence in circuit applications.

Engineering Selection Recommendations

All three substitute parts are functionally equivalent to the SMAJ60CA-13 based on electrical specifications. Selection should be based on the following factors:

SMAJ60CA-13-F (Diodes Incorporated): Direct manufacturer equivalent with identical specifications and temperature range. ROHS3 compliant. Available in cut tape and Digi-Reel packaging. Recommended for designs requiring continuity with the original manufacturer.

SMAJ60CA (MDD): Alternative manufacturer source with ROHS3 compliance. Operating temperature range is -50°C to 150°C (1°C lower minimum). Highest inventory availability (17,241 pcs). Suitable for applications not requiring the full -55°C minimum temperature specification.

SMAJ60CA-TP (Micro Commercial Co): Manufacturer-recommended substitute with ROHS3 compliance and extended operating temperature range (-55°C to 175°C). Available in tape & reel packaging with highest inventory (104,544 pcs). Provides the widest temperature operating margin.

Frequently Asked Questions (FAQ)

Q: Can SMAJ60CA-13-F be used as a direct replacement for SMAJ60CA-13?

A: Yes. SMAJ60CA-13-F is a direct equivalent from the same manufacturer with identical electrical specifications, voltage ratings, current handling, and temperature range. The primary difference is product status (active vs. discontinued) and packaging format.

Q: What is the difference between SMAJ60CA-13 and SMAJ60CA (MDD)?

A: Both parts have identical electrical specifications (60V standoff, 96.8V clamping, 4.1A peak pulse). The MDD variant has a minimum operating temperature of -50°C instead of -55°C. Both are ROHS3 compliant. Selection depends on whether the -55°C minimum is required for your application.

Q: Is SMAJ60CA-TP compatible with existing PCB layouts designed for SMAJ60CA-13?

A: Yes. SMAJ60CA-TP uses the same DO-214AC (SMA) package and has identical electrical specifications. It can be used as a direct footprint replacement. The extended temperature range (-55°C to 175°C) provides additional operational margin.

Q: What does the packaging designation mean (CT, TP, bulk)?

A: CT (Cut Tape) and TP (Tape & Reel) refer to supply formats for automated assembly. Bulk packaging is for manual handling. All formats contain electrically identical components; packaging choice depends on assembly process requirements and order quantities.

Q: Are all substitutes RoHS compliant?

A: SMAJ60CA-13-F, SMAJ60CA (MDD), and SMAJ60CA-TP are all ROHS3 compliant. The original SMAJ60CA-13 is RoHS non-compliant. If RoHS compliance is required, use one of the three substitute parts.

Q: Which substitute has the best inventory availability?

A: SMAJ60CA-TP (Micro Commercial Co) has the highest inventory at 104,544 pcs, followed by SMAJ60CA (MDD) at 17,241 pcs, and SMAJ60CA-13-F at 1,900 pcs.
