SMAJ100CA-TP Equivalent & Substitute Parts

Part Overview

The SMAJ100CA-TP is a Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose transient voltage protection in surface-mount applications. This bidirectional Zener diode operates with a 100V reverse standoff voltage and provides 162V maximum clamping voltage at peak pulse current. The component is actively produced and widely used in circuit protection applications requiring DO-214AC (SMA) package form factor. Substitute parts are identified when electrical characteristics and mechanical compatibility align with the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMAJ100CA-TP are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Voltage - Reverse Standoff (Typ): 100V
• Voltage - Breakdown (Min): 111V
• Voltage - Clamping (Max) @ Ipp: 162V
• Current - Peak Pulse (10/1000µs): 2.5A
• Power - Peak Pulse: 400W
• Type: Zener
• Bidirectional Channels: 1

Mechanical Parameters (Must Match):

• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount

Compliance Parameters (Must Match):

• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts maintain identical electrical performance and mechanical compatibility with the original SMAJ100CA-TP specification.

Parameter Comparison

Engineering Selection Recommendations

All three parts meet the core electrical and mechanical requirements for direct substitution. Selection should be based on the following factors:

SMAJ100CA (MDD): This part maintains all critical electrical parameters and compliance certifications. Operating temperature range is -50°C to 150°C (TJ), which is narrower than the original specification. This part is suitable for applications where the ambient temperature remains within this range.

SMAJ100CA-13-F (Diodes Incorporated): This part maintains all critical electrical parameters, compliance certifications, and REACH status. Operating temperature range is -55°C to 150°C (TJ), providing broader low-temperature coverage than the MDD variant. Packaging is specified as Tape & Reel (TR), consistent with the original SMAJ100CA-TP format.

SMAJ100CA-TP (Micro Commercial Co): The original part specification with operating temperature range of -55°C to 175°C (TA), providing the widest temperature coverage. REACH status is confirmed as REACH Unaffected.

All parts are actively produced and carry ROHS3 compliance with MSL 1 (Unlimited) moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can SMAJ100CA (MDD) be used as a direct replacement for SMAJ100CA-TP?

A: Yes, for applications operating within -50°C to 150°C. All electrical parameters (100V standoff, 162V clamping, 2.5A peak pulse) and mechanical specifications (DO-214AC SMA package, surface mount) are identical. Verify your application's operating temperature range does not exceed these limits.

Q: What is the difference between SMAJ100CA-TP and SMAJ100CA-13-F?

A: Both parts have identical electrical characteristics and package form factor. The primary difference is operating temperature range: SMAJ100CA-TP operates -55°C to 175°C (TA), while SMAJ100CA-13-F operates -55°C to 150°C (TJ). SMAJ100CA-13-F is supplied in Tape & Reel packaging.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three parts carry ROHS3 Compliant certification and MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and handling requirements.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. All parts use identical DO-214AC (SMA) package specifications and surface-mount technology. PCB footprints and assembly processes remain unchanged across all three variants.

Q: Which part should I select for high-temperature applications?

A: The SMAJ100CA-TP (Micro Commercial Co) supports the highest operating temperature at 175°C (TA). For applications requiring operation above 150°C, this part is the appropriate selection.
