Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PESD1FLEX,215 is determined by the following critical parameters:

• Voltage - Reverse Standoff: 24V (Max)
• Voltage - Breakdown (Min): 25.4V
• Voltage - Clamping (Max) @ Ipp: 70V
• Current - Peak Pulse (8/20µs): 3A
• Power - Peak Pulse: 200W
• Package / Case: TO-236-3, SC-59, SOT-23-3
• Bidirectional Channels: 2
• Mounting Type: Surface Mount

Substitute parts are classified into two categories:

Direct Substitutes maintain all critical electrical parameters (voltage standoff, breakdown voltage, clamping voltage, and peak pulse current) and identical package specifications. These parts are functionally interchangeable with the PESD1FLEX,215.

Similar Substitutes share the same package and mounting type but exhibit variations in one or more electrical parameters, such as clamping voltage, peak pulse current, or frequency-dependent capacitance. These parts require engineering evaluation for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Nexperia USA Inc. Parts):

PESD1CAN,215, PESD1CANVL, and PESD24VL2BT,215 are direct electrical and mechanical equivalents to the PESD1FLEX,215. All three parts maintain identical voltage ratings, clamping characteristics, and peak pulse current specifications. Selection among these Nexperia parts should be based on packaging format availability (Tape & Reel versus Cut Tape & Digi-Reel) and application-specific requirements. PESD1CAN,215 and PESD1CANVL carry AEC-Q101 qualification, providing enhanced reliability documentation for automotive CAN bus applications.

Active Alternative (Diodes Incorporated):

DESD1CAN2SOQ-7 from Diodes Incorporated provides equivalent electrical performance with Active product status, eliminating obsolescence concerns associated with "Not For New Designs" classifications. This part maintains all critical voltage and current parameters and carries AEC-Q101 qualification. The SOT-23-3 package is mechanically compatible with the TO-236AB footprint.

Similar Alternatives (Parameter Variations):

CDSOT23-T24CAN (Bourns Inc.) and ESDCAN01-2BLY (STMicroelectronics) exhibit reduced clamping voltage (40V versus 70V) and increased peak pulse current capability (8A and 5.5A respectively). These parts are suitable only for applications where the lower clamping voltage is acceptable and the higher current handling provides design margin. ESDCAN01-2BLY maintains automotive qualification (AEC-Q101) and Active product status.

Frequently Asked Questions (FAQ)

Q: Can PESD1CAN,215 directly replace PESD1FLEX,215 in existing designs?

A: Yes. PESD1CAN,215 is a direct electrical and mechanical equivalent with identical voltage ratings, clamping characteristics, and package specifications. The primary difference is packaging format (Cut Tape & Digi-Reel versus Tape & Reel) and enhanced automotive qualification (AEC-Q101).

Q: What is the significance of the "Not For New Designs" status?

A: This designation indicates the manufacturer is not recommending the part for new circuit designs. However, the part remains available for existing production and maintenance applications. Direct substitutes with Active status, such as DESD1CAN2SOQ-7, are preferred for new designs.

Q: Are CDSOT23-T24CAN and ESDCAN01-2BLY suitable replacements?

A: These parts share the same package and mounting type but feature reduced clamping voltage (40V versus 70V) and increased peak pulse current. They are suitable only if the application can tolerate lower clamping voltage and does not require the 70V clamping specification of the original part.

Q: What is the difference between TO-236AB and SOT-23-3 packages?

A: TO-236AB and SOT-23-3 are equivalent package designations for the same three-lead surface-mount component. Both packages are mechanically and electrically compatible for this TVS diode application.

Q: Which substitute offers the best long-term availability?

A: DESD1CAN2SOQ-7 from Diodes Incorporated carries Active product status, indicating ongoing manufacturer support and availability. This part is recommended for new designs requiring long-term component availability assurance.

Q: Are all listed substitutes RoHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), matching the environmental and handling specifications of the PESD1FLEX,215.
