SMAJ60A-TP Equivalent & Substitute Parts
Part Overview
The SMAJ60A-TP is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose transient voltage protection in surface-mount applications. This component features a 60V reverse standoff voltage with a maximum clamping voltage of 96.8V at peak pulse current, housed in a DO-214AC (SMA) package. The part is actively produced and ROHS3 compliant, making it suitable for modern electronic circuit protection requirements.
Equivalent and substitute parts are identified based on matching electrical performance parameters, package compatibility, and compliance certifications. Substitutes maintain identical or functionally equivalent voltage ratings, peak pulse current specifications, and thermal operating ranges within acceptable engineering tolerances.

Substitute Part Grouping Explanation
Substitute parts for the SMAJ60A-TP are qualified based on the following critical parameters:
- Voltage - Reverse Standoff: 60V (exact match required)
- Voltage - Clamping (Max) @ Ipp: 96.8V (exact match required)
- Current - Peak Pulse (10/1000µs): 4.1A or 4.13A (within acceptable tolerance)
- Package / Case: DO-214AC, SMA (mechanical and electrical compatibility)
- Type: Zener, Unidirectional (functional equivalence)
- RoHS Status: ROHS3 Compliant (regulatory compliance)
- Moisture Sensitivity Level: 1 (Unlimited) (handling and storage compatibility)
All identified substitutes maintain these core electrical and mechanical specifications. Variations in operating temperature range and packaging format (Cut Tape vs. Tape & Reel) do not affect functional equivalence for circuit protection applications.

Engineering Selection Recommendations
All identified substitute parts maintain full electrical and mechanical compatibility with the SMAJ60A-TP. Selection among these equivalents should be based on:
Manufacturer Availability: SMAJ60A-E3/61 (Vishay) and SMAJ60A-E3/5A (Vishay) offer the highest inventory levels (25,962 and 4,622 units respectively), followed by SMAJ60A (Meritek) at 77,620 units. SMAJ60A-13-F (Diodes Incorporated) provides 15,955 units in stock.
Packaging Format: SMAJ60A-E3/61 is available in Cut Tape (CT) & Digi-Reel® format. SMAJ60A-13-F is supplied in Tape & Reel (TR) format. SMAJ60A-TP (original part) is supplied in Cut Tape (CT). SMAJ60A (Meritek) packaging format is not specified. Selection should align with assembly line requirements and handling procedures.
Operating Temperature: SMAJ60A-TP supports -55°C to 175°C (ambient temperature basis), while all substitute parts are rated -55°C to 150°C (junction temperature basis). For applications requiring operation above 150°C junction temperature, the SMAJ60A-TP provides extended thermal capability.

Frequently Asked Questions (FAQ)
Q: Can SMAJ60A-E3/5A substitute for SMAJ60A-TP in all applications?
A: Yes. Both parts maintain identical voltage ratings (60V reverse standoff, 96.8V clamping), peak pulse current (4.1A), power dissipation (400W), and package configuration (DO-214AC, SMA). Both are ROHS3 compliant with MSL 1 rating. The primary difference is operating temperature range: SMAJ60A-TP supports -55°C to 175°C ambient, while SMAJ60A-E3/5A supports -55°C to 150°C junction. For applications within 150°C junction temperature limits, substitution is direct.
Q: What is the difference between SMAJ60A (Meritek) and SMAJ60A-TP?
A: Both parts share identical electrical specifications: 60V reverse standoff, 96.8V clamping voltage, and 400W peak pulse power. Peak pulse current differs slightly: SMAJ60A-TP specifies 4.1A while Meritek SMAJ60A specifies 4.13A, representing a 0.73% variance within acceptable engineering tolerance. Both use DO-214AC (SMA) packaging and are ROHS3 compliant. Operating temperature range differs: SMAJ60A-TP supports -55°C to 175°C ambient, while Meritek SMAJ60A supports -55°C to 150°C ambient.
Q: Are Vishay TransZorb® parts (SMAJ60A-E3/5A and SMAJ60A-E3/61) equivalent to the standard SMAJ60A-TP?
A: Yes. Both Vishay TransZorb® variants maintain the same electrical performance: 60V reverse standoff, 96.8V clamping, 4.1A peak pulse current, and 400W power dissipation. Both are housed in DO-214AC (SMA) packages and are ROHS3 compliant with MSL 1 rating. The TransZorb® designation is a Vishay product line identifier and does not affect functional equivalence. Operating temperature is -55°C to 150°C (junction basis) for both Vishay parts.
Q: What packaging format differences exist among substitute parts?
A: SMAJ60A-TP is supplied in Cut Tape (CT) format. SMAJ60A-13-F (Diodes Incorporated) is supplied in Tape & Reel (TR) format. SMAJ60A-E3/61 (Vishay) is available in Cut Tape (CT) & Digi-Reel® format. SMAJ60A-E3/5A (Vishay) is supplied in Tape & Reel (TR) format. SMAJ60A (Meritek) packaging format is not specified. Selection should align with assembly equipment compatibility and procurement requirements.
Q: Do all substitute parts meet the same compliance standards as SMAJ60A-TP?
A: Yes. All identified substitute parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.10.0080. All maintain Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.
Q: Which substitute part offers the best inventory availability?
A: SMAJ60A (Meritek) provides the highest inventory level at 77,620 units in stock. SMAJ60A-E3/61 (Vishay) offers 25,962 units, SMAJ60A-13-F (Diodes Incorporated) provides 15,955 units, and SMAJ60A-E3/5A (Vishay) offers 4,622 units.
