CD214L-T36CALF Equivalent & Substitute Parts

Part Overview

The CD214L-T36CALF is a transient voltage suppressor (TVS) diode manufactured by Bourns Inc., designed for general-purpose overvoltage protection in surface mount applications. This component features a 36V reverse standoff voltage with a 58.1V maximum clamping voltage and 51.6A peak pulse current capability in a DO-214AB (SMC) package. The part is currently obsolete, making equivalent substitutes necessary for ongoing design support and production requirements.

Substitute Part Grouping Explanation

Substitution for the CD214L-T36CALF is determined by strict electrical and mechanical parameter matching:

Critical Matching Parameters:

Voltage - Reverse Standoff (Typ): 36V
Voltage - Clamping (Max) @ Ipp: 58.1V
Voltage - Breakdown (Min): 40V
Package / Case: DO-214AB, SMC
Mounting Type: Surface Mount
Bidirectional Channels: 1

Substitute parts are grouped into two categories based on peak pulse current and power dissipation capabilities:

Direct Equivalents (3kW Class): Parts with 51.6A to 51.7A peak pulse current and 3000W power rating maintain identical electrical performance to the original component.

Enhanced Performance Substitutes (5kW Class): Parts with 86.1A peak pulse current and 5000W power rating provide superior transient protection while maintaining voltage specifications. These are suitable for applications requiring higher surge capacity.

Engineering Selection Recommendations

For Direct Replacement (Identical Performance): SMLJ36CA (Bourns Inc.) and SMDJ36CA (Alpha & Omega Semiconductor Inc.) provide electrical equivalence to the original CD214L-T36CALF with matching 51.6A to 51.7A peak pulse current and 3000W power dissipation. Both are active products with ROHS3 compliance. SMLJ36CA is available in Tape & Reel packaging, while SMDJ36CA is available in bulk form.

For Enhanced Protection (Higher Surge Capacity): 5.0SMDJ36CA (HY Electronic) and 5.0SMDJ36CA-T7 (Littelfuse Inc.) maintain identical voltage specifications while providing 86.1A peak pulse current and 5000W power dissipation. These parts are suitable for applications requiring superior transient suppression. 5.0SMDJ36CA-T7 offers extended operating temperature range to 175°C and is available in Tape & Reel packaging.

For Cost-Optimized Applications: SMCJ36CA (EVVO Semi) and SMCJ36CA-TP (Micro Commercial Co) provide voltage-compliant substitution with reduced peak pulse current (25.9A) and power rating (1500W). These are appropriate for applications with lower transient energy requirements. SMCJ36CA-TP supports extended operating temperature to 175°C.

All substitute parts maintain ROHS3 compliance and DO-214AB (SMC) package compatibility with the original component.

Frequently Asked Questions (FAQ)

Q: Can SMCJ36CA replace CD214L-T36CALF in all applications? A: SMCJ36CA maintains voltage specifications (36V standoff, 58.1V clamping) but has reduced peak pulse current (25.9A vs. 51.6A) and power dissipation (1500W vs. 3000W). It is suitable only for applications with lower transient energy requirements.

Q: What is the difference between 3kW and 5kW rated substitutes? A: The 5kW-rated parts (5.0SMDJ36CA and 5.0SMDJ36CA-T7) handle higher peak pulse currents (86.1A) and provide greater surge protection capability. Voltage specifications remain identical. Selection depends on the transient energy profile of the application.

Q: Are all substitutes compatible with the original DO-214AB footprint? A: Yes. All listed substitutes use the DO-214AB (SMC) package and are mechanically compatible with the original CD214L-T36CALF footprint.

Q: Does packaging type affect electrical performance? A: No. Tape & Reel (TR) and bulk packaging formats contain identical components. Packaging selection is based on production volume and assembly process requirements.

Q: Which substitute offers the widest operating temperature range? A: SMCJ36CA-TP and 5.0SMDJ36CA-T7 both support -55°C to 175°C operating range, compared to the original -55°C to 150°C specification.

Q: Are all substitutes ROHS3 compliant? A: Yes. All listed substitutes meet ROHS3 compliance requirements, matching the original component's environmental certification.
