CPDER12V Equivalent & Substitute Parts Reference

Part Overview

The CPDER12V is a transient voltage suppressor (TVS) diode manufactured by Comchip Technology, designed for general-purpose overvoltage protection applications. This surface-mount component features a 12V reverse standoff voltage with a 25V maximum clamping voltage and 1A peak pulse current rating in the 0503/SOD-723F package. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating, making it suitable for standard industrial and commercial electronic applications requiring transient voltage suppression.

Alternative part numbers may be required due to inventory availability, packaging format preferences, or specific application constraints where substitute electrical characteristics remain within acceptable operating parameters.

Substitute Part Grouping Explanation

The substitute parts listed for CPDER12V are D5V0L1B2LP-7B and D5V0L1B2LP4-7B, both manufactured by Diodes Incorporated. These substitutes are identified based on the following criteria:

Substitution Logic:

• Both substitute parts maintain Zener diode type classification with single bidirectional channel configuration
• Surface-mount technology compatibility is preserved across all parts
• RoHS3 compliance and MSL 1 (Unlimited) rating are maintained
• General-purpose application category alignment
• Active product status across all alternatives

Critical Parameters for Substitution Assessment:

• Voltage - Reverse Standoff: Substitute parts operate at 5V (Max), which differs from the 12V specification of CPDER12V
• Voltage - Breakdown (Min): Substitute parts specify 6V minimum versus 13V for CPDER12V
• Voltage - Clamping (Max) @ Ipp: Substitute parts clamp at 14V maximum versus 25V for CPDER12V
• Current - Peak Pulse (8/20µs): Substitute parts support 6A versus 1A for CPDER12V
• Power - Peak Pulse: Substitute parts dissipate 84W versus 25W for CPDER12V
• Package / Case: Substitute parts use 0402 (1006 Metric) versus 0503 (1308 Metric) for CPDER12V

These substitutes represent different voltage protection classes and are not electrically interchangeable with CPDER12V for applications requiring 12V standoff voltage protection.

Parameter Comparison

Engineering Selection Recommendations

Component selection between CPDER12V and the listed substitutes must be based on the specific voltage protection requirements of the target application:

CPDER12V Selection Criteria:

• Applications requiring 12V reverse standoff voltage protection
• Circuits where transient clamping must not exceed 25V
• Systems designed for 1A peak pulse current handling
• Designs utilizing 0503/SOD-723F package footprint
• Tape & Reel packaging requirement for automated assembly

D5V0L1B2LP-7B and D5V0L1B2LP4-7B Selection Criteria:

• Applications requiring 5V reverse standoff voltage protection
• Circuits where transient clamping must not exceed 14V
• Systems designed for 6A peak pulse current handling
• Designs utilizing 0402 (1006 Metric) package footprint
• D5V0L1B2LP-7B: Cut Tape or Digi-Reel® packaging format
• D5V0L1B2LP4-7B: Tape & Reel packaging format

All three parts maintain active product status, full RoHS3 compliance, and unlimited moisture sensitivity rating, ensuring regulatory and environmental compatibility across all options.

Frequently Asked Questions (FAQ)

Q: Can D5V0L1B2LP-7B or D5V0L1B2LP4-7B be used as direct replacements for CPDER12V?

A: No. These parts operate in different voltage protection classes. CPDER12V provides 12V standoff voltage protection with 25V maximum clamping, while the Diodes Incorporated substitutes provide 5V standoff voltage protection with 14V maximum clamping. Direct substitution is only appropriate when the application voltage protection requirements match the component specifications.

Q: What is the difference between D5V0L1B2LP-7B and D5V0L1B2LP4-7B?

A: Both parts are electrically identical with matching voltage, current, and power specifications. The primary difference is packaging format: D5V0L1B2LP-7B is supplied in Cut Tape (CT) or Digi-Reel® format, while D5V0L1B2LP4-7B is supplied in Tape & Reel (TR) format. Selection depends on assembly process requirements and inventory handling preferences.

Q: Are there package compatibility considerations when substituting these TVS diodes?

A: Yes. CPDER12V uses the 0503 (1308 Metric) package, while both Diodes Incorporated substitutes use the 0402 (1006 Metric) package. These are different physical footprints requiring separate PCB layout designs. Package selection must align with the target circuit board design specifications.

Q: Do all three parts meet the same compliance standards?

A: Yes. CPDER12V, D5V0L1B2LP-7B, and D5V0L1B2LP4-7B all maintain RoHS3 compliance, REACH Unaffected status, MSL 1 (Unlimited) rating, and active product status. Regulatory and environmental requirements are equivalent across all options.

Q: What peak pulse current capacity should be considered when selecting between these parts?

A: CPDER12V handles 1A peak pulse current (8/20µs), while both Diodes Incorporated substitutes handle 6A peak pulse current (8/20µs). Applications requiring higher transient current suppression capacity may benefit from the increased current rating of the substitute parts, provided voltage protection requirements align with the 5V standoff specification.
