CD214C-T36ALF Equivalent & Substitute Parts

Part Overview

The CD214C-T36ALF is a 36V Transient Voltage Suppressor (TVS) diode manufactured by Bourns Inc., packaged in DO-214AB (SMC) surface mount configuration. This unidirectional Zener diode is designed for general-purpose transient voltage protection with a peak pulse power rating of 1500W and peak pulse current of 25.8A at 10/1000µs waveform. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. Alternative sources provide functionally equivalent or enhanced performance options while maintaining compatibility with the original electrical specifications.

Electrical Parameters:

Voltage - Reverse Standoff (Typ): 36V
Voltage - Breakdown (Min): 40V
Voltage - Clamping (Max) @ Ipp: 58.1V
Current - Peak Pulse (10/1000µs): 25.8A minimum
Power - Peak Pulse: 1500W minimum

Mechanical Parameters:

Package / Case: DO-214AB, SMC (surface mount)
Mounting Type: Surface Mount
Unidirectional Channels: 1

Compliance Parameters:

RoHS3 Compliant
MSL: 1 (Unlimited)

Substitute parts are grouped into two categories:

Direct Equivalents: Parts with identical electrical specifications (36V standoff, 58.1V clamp, 25.8-25.9A peak pulse current, 1500W power rating) and matching DO-214AB SMC package. These provide pin-for-pin and functional compatibility.

Enhanced Performance Alternatives: Parts with identical voltage specifications but higher peak pulse current (86.1A) and power ratings (5000W). These provide superior transient protection capability while maintaining the same voltage protection thresholds and package form factor.

Engineering Selection Recommendations

Direct Replacement (Identical Specifications):

SMCJ36A-13-F (Diodes Incorporated) and SMCJ36A-HR (Littelfuse Inc.) are the primary direct replacements for CD214C-T36ALF. Both maintain identical electrical parameters (36V standoff, 58.1V clamp, 25.8-25.9A peak pulse current, 1500W power), matching DO-214AB SMC package, and active product status. Both are ROHS3 compliant with MSL 1 rating. SMCJ36A-13-F supports extended operating temperature range (-55°C ~ 150°C), while SMCJ36A-HR extends to -65°C minimum. SMCJ36A-TP (Micro Commercial Co) offers the widest temperature range (-55°C ~ 175°C) with identical electrical specifications.

Enhanced Performance Alternative:

5.0SMDJ36A-T7 (Littelfuse Inc.) and 5.0SMDJ36A (Taiwan Semiconductor Corporation) provide superior transient protection with 86.1A peak pulse current and 5000W power rating while maintaining the same 36V standoff and 58.1V clamping voltages. Both use DO-214AB SMC package and are ROHS3 compliant. These are suitable for applications requiring higher transient energy absorption. 5.0SMDJ36A-T7 supports -65°C ~ 150°C operating range, while 5.0SMDJ36A extends to -55°C ~ 175°C.

Package Consideration:

SMCJ36A (EVVO Semi) uses DO-214AC SMA package instead of DO-214AB SMC. While electrically equivalent (36V standoff, 58.1V clamp, 25.9A peak pulse current), the different package form factor requires PCB layout modification and is not a direct pin-for-pin replacement.

All recommended substitutes are ROHS3 compliant and carry MSL 1 rating, meeting the compliance requirements of the original part.

Frequently Asked Questions (FAQ)

Q: Can SMCJ36A (EVVO Semi) be used as a direct replacement for CD214C-T36ALF?

A: SMCJ36A is electrically equivalent but uses DO-214AC SMA package instead of DO-214AB SMC. This requires PCB layout modification. For direct pin-for-pin replacement without layout changes, use SMCJ36A-13-F or SMCJ36A-HR instead.

Q: What is the difference between the direct equivalents and the 5.0SMDJ36A series?

A: Direct equivalents (SMCJ36A-13-F, SMCJ36A-HR, SMCJ36A-TP) maintain identical peak pulse current (25.8-25.9A) and power rating (1500W). The 5.0SMDJ36A series provides enhanced performance with 86.1A peak pulse current and 5000W power rating. Both maintain the same voltage protection thresholds (36V standoff, 58.1V clamp). Select 5.0SMDJ36A series for applications requiring higher transient energy absorption.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) rating, matching the compliance profile of the original CD214C-T36ALF.

Q: Which substitute offers the widest operating temperature range?

A: SMCJ36A-TP (Micro Commercial Co) and 5.0SMDJ36A (Taiwan Semiconductor Corporation) both support -55°C ~ 175°C operating range, providing the widest temperature coverage among available substitutes.

Q: Can I use SMCJ36A-HR variants interchangeably?

A: SMCJ36A-HR, SMCJ36A-HRA, and SMCJ36A-HRAT7 share identical electrical specifications (36V standoff, 58.1V clamp, 25.9A peak pulse current, 1500W power) and DO-214AB SMC package. All are active products from Littelfuse with ROHS3 compliance. They are functionally interchangeable for the same application requirements.

Q: What is the impact of lower power rating in SMCJ36A (EVVO Semi)?

A: SMCJ36A (EVVO Semi) has 600W peak pulse power rating compared to 1500W in the original CD214C-T36ALF. This reduced power rating may limit transient energy absorption capability. Use this part only if application transient energy requirements are confirmed to be within 600W limits. For equivalent power handling, use SMCJ36A-13-F, SMCJ36A-HR, or SMCJ36A-TP instead.
