5KP12CE3/TR13 Equivalent & Substitute Parts

Part Overview

The 5KP12CE3/TR13 is a bidirectional transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This through-hole component features a 12V reverse standoff voltage with a 22V maximum clamping voltage and 5000W peak pulse power rating. The device is actively produced and fully compliant with RoHS3 and REACH regulations. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when packaging format requirements differ.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP12CE3/TR13 are identified based on strict electrical and mechanical parameter matching within the TVS diode category. The substitution criteria are:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 12V
• Voltage - Breakdown (Min): 13.3V
• Bidirectional Channels: 1
• Mounting Type: Through Hole
• Package / Case: P600, Axial
• Power - Peak Pulse: 5000W
• Operating Temperature Range: -55°C to 175°C
• RoHS3 Compliance
• MSL Rating: 1 (Unlimited)

Allowable Variation Parameters:

• Voltage - Clamping (Max) @ Ipp: Acceptable range 19.9V to 22V
• Current - Peak Pulse (10/1000µs): Acceptable range 227A to 256.3A
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT) formats are interchangeable for component selection purposes

The 5KP12CA from Littelfuse Inc. meets all critical matching parameters and operates within the allowable variation range for clamping voltage and peak pulse current.

Parameter Comparison

Engineering Selection Recommendations

Both the 5KP12CE3/TR13 and 5KP12CA are active products with full RoHS3 compliance and REACH unaffected status, making them suitable for current design implementations and regulatory requirements.

The 5KP12CE3/TR13 (Microchip Technology) provides a clamping voltage of 22V with peak pulse current of 227A in Tape & Reel packaging format.

The 5KP12CA (Littelfuse Inc.) provides a clamping voltage of 19.9V with peak pulse current of 256.3A in Cut Tape packaging format. The lower clamping voltage and higher peak pulse current represent tighter voltage regulation characteristics within the same power class.

Selection between these parts should be based on packaging availability, lead time, inventory status, and specific application requirements for clamping voltage precision. Both devices maintain identical reverse standoff voltage, breakdown voltage, power rating, temperature range, and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the 5KP12CA substitute for the 5KP12CE3/TR13 in my circuit?

A: Yes. Both devices share identical reverse standoff voltage (12V), breakdown voltage (13.3V), peak pulse power (5000W), package type (P600 Axial), mounting method (Through Hole), operating temperature range (-55°C to 175°C), and regulatory compliance (RoHS3, REACH). The 5KP12CA operates within acceptable tolerance for clamping voltage and peak pulse current specifications.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel and Cut Tape are packaging and delivery formats for the same component. Tape & Reel is supplied on continuous carrier tape wound on a reel for automated assembly. Cut Tape is supplied as individual segments cut from the carrier tape. Both formats contain identical electronic components in the same P600 Axial package.

Q: Are there any temperature or compliance differences between these parts?

A: No. Both the 5KP12CE3/TR13 and 5KP12CA operate across the identical temperature range of -55°C to 175°C (TJ) and maintain the same RoHS3 compliance and REACH unaffected status. Moisture Sensitivity Level is 1 (Unlimited) for both devices.

Q: What does "Voltage - Clamping (Max) @ Ipp" mean?

A: This parameter specifies the maximum voltage across the TVS diode when peak pulse current (Ipp) flows through it during a transient event. The 5KP12CE3/TR13 clamps at a maximum of 22V, while the 5KP12CA clamps at 19.9V. Lower clamping voltage provides tighter protection of downstream circuitry.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes. Both devices use identical P600 Axial through-hole package dimensions and pinout, allowing direct mechanical and electrical substitution on the same printed circuit board layout.

Q: What is the significance of the 12V Reverse Standoff Voltage?

A: The 12V reverse standoff voltage indicates the maximum continuous voltage the TVS diode can withstand without conducting. The device remains in a high-impedance state below this threshold and activates to suppress transients above the breakdown voltage of 13.3V.
