PESD1CANVL Equivalent & Substitute Parts

Part Overview

The PESD1CANVL is a bidirectional Transient Voltage Suppressor (TVS) diode manufactured by Nexperia USA Inc., designed for CAN bus protection applications. This surface-mount component operates with a 24V reverse standoff voltage and provides 70V clamping at peak pulse current, making it suitable for automotive-grade transient suppression in CAN communication networks. The part carries a "Not For New Designs" status, necessitating identification of equivalent alternatives for ongoing production and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PESD1CANVL is determined by the following critical parameters:

Primary Substitution Criteria (Direct Equivalents):

• 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
• Bidirectional Channels: 2
• Package / Case: TO-236-3, SC-59, SOT-23-3
• Mounting Type: Surface Mount
• Applications: CAN
• Grade: Automotive
• RoHS Status: ROHS3 Compliant

Direct Equivalents maintain all critical electrical and mechanical parameters, differing only in manufacturer, product status, or packaging format (Cut Tape vs. Tape & Reel).

Similar Parts share the same voltage class and package footprint but may exhibit variations in clamping voltage, peak pulse current, or capacitance characteristics. These parts are suitable only when circuit design tolerances accommodate the parameter deviations.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Recommended for Replacement):

PESD1CAN,215, PESD1FLEX,215, and PESD24VL2BT,215 are functionally equivalent to PESD1CANVL, maintaining identical electrical specifications across voltage, current, and power parameters. All three parts are manufactured by Nexperia and carry "Not For New Designs" status. Selection between these options depends on packaging requirements: PESD1CAN,215 and PESD24VL2BT,215 are available in Tape & Reel format, while PESD1FLEX,215 offers flexible packaging options. PESD1CAN,215 carries AEC-Q101 qualification, providing enhanced reliability assurance compared to the AEC-Q100 qualification of the original part.

Active Production Alternative:

DESD1CAN2SOQ-7 (Diodes Incorporated) is an active-status direct electrical equivalent with identical voltage, current, and power specifications. This part maintains the same 24V reverse standoff, 70V clamping voltage, and 3A peak pulse current. It carries AEC-Q101 qualification and is available in active production, making it suitable for new designs requiring CAN bus protection. The part is supplied in SOT-23-3 package format.

Similar Parts (Limited Substitution):

CDSOT23-T24CAN (Bourns Inc.) shares the 24V voltage class and SOT-23-3 package but exhibits reduced clamping voltage (40V vs. 70V) and increased peak pulse current capability (8A vs. 3A). This part is suitable only when circuit design accommodates the lower clamping voltage specification.

CPDT-5V0C-HF (Comchip Technology) operates at 5V voltage class and is not suitable as a substitute for 24V CAN bus applications.

Frequently Asked Questions (FAQ)

Q: Can PESD1CAN,215 directly replace PESD1CANVL in existing designs?

A: Yes. PESD1CAN,215 maintains identical electrical specifications including 24V reverse standoff, 25.4V breakdown voltage, 70V clamping voltage, and 3A peak pulse current. Both parts are surface-mount in TO-236-3/SOT-23-3 packages. The primary difference is packaging format (Cut Tape vs. Tape & Reel) and AEC qualification level (AEC-Q101 vs. AEC-Q100).

Q: What is the difference between PESD1FLEX,215 and PESD1CAN,215?

A: Both parts are Nexperia products with identical electrical specifications. PESD1FLEX,215 is specified for general-purpose applications and features capacitance measurement at 5MHz, while PESD1CAN,215 is specified for CAN applications with capacitance measurement at 1MHz. Electrical performance parameters remain equivalent.

Q: Is DESD1CAN2SOQ-7 suitable for new CAN bus designs?

A: Yes. DESD1CAN2SOQ-7 is an active-status product with identical electrical specifications to PESD1CANVL. It maintains 24V reverse standoff, 70V clamping voltage, and 3A peak pulse current. AEC-Q101 qualification provides enhanced reliability assurance. The part is available in active production.

Q: Why does CDSOT23-T24CAN have different clamping voltage?

A: CDSOT23-T24CAN is a similar part from Bourns Inc. that operates in the same 24V voltage class but exhibits 40V clamping voltage compared to 70V in PESD1CANVL. This lower clamping voltage may be acceptable in applications with different transient suppression requirements, but circuit validation is necessary to confirm compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status, meeting environmental and material restriction requirements.

Q: What is the operating temperature range difference between parts?

A: PESD1CANVL, PESD1CAN,215, PESD1FLEX,215, and PESD24VL2BT,215 operate from -65°C to 150°C (TA). DESD1CAN2SOQ-7 operates from -65°C to 150°C (TJ). CDSOT23-T24CAN operates from -40°C to 150°C (TJ), providing a narrower low-temperature range.
