CD214A-T36ALF Equivalent & Substitute Parts

Part Overview

The CD214A-T36ALF is a Transient Voltage Suppressor (TVS) diode manufactured by Bourns Inc., designed for general-purpose overvoltage protection in surface-mount applications. This part operates with a 36V reverse standoff voltage and provides 58.1V clamping at peak pulse current. The CD214A-T36ALF is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Active alternatives with identical or compatible electrical specifications are available from multiple manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD214A-T36ALF is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 36V
• Voltage - Breakdown (Min): 40V
• Voltage - Clamping (Max) @ Ipp: 58.1V
• Current - Peak Pulse (10/1000µs): 6.9A (±0.02A tolerance acceptable)
• Power - Peak Pulse: 400W
• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount
• Type: Zener, Unidirectional

Substitute parts must maintain identical voltage specifications and current ratings within the specified tolerance band. Package compatibility (DO-214AC/SMA) and surface-mount configuration are mandatory for direct board-level replacement. All listed substitutes meet these criteria and are classified as active products with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are active products with current manufacturing availability, addressing the obsolescence of the CD214A-T36ALF. Selection among substitutes should be based on the following criteria:

SMAJ36A (MDD) provides direct electrical equivalence with active product status and high inventory availability (7870 pcs). This part is suitable for standard applications requiring the specified 36V/58.1V protection characteristics.

SMAJ36A-TP (Micro Commercial Co) offers the widest operating temperature range (-55°C ~ 175°C) and is supplied in Tape & Reel packaging, making it appropriate for high-volume production environments. This variant extends thermal performance beyond the original specification.

SZ1SMA36AT3G (Littelfuse) includes automotive-grade qualification (AEC-Q101) and the lowest operating temperature rating (-65°C ~ 150°C), with documented capacitance specification (345pF @ 1MHz). This part is suitable for automotive and temperature-critical applications.

TV04A360J-G (Comchip) maintains electrical equivalence with peak pulse current of 6.88A (within tolerance of the 6.9A specification) and is available in active production status. This part provides an alternative source for supply chain diversification.

All substitute parts maintain ROHS3 compliance and identical package/case specifications (DO-214AC, SMA) for direct board-level replacement without design modification.

Frequently Asked Questions (FAQ)

Q: Can SMAJ36A-TP be used as a direct replacement for CD214A-T36ALF?

A: Yes. SMAJ36A-TP meets all electrical specifications (36V standoff, 40V breakdown, 58.1V clamping, 6.9A peak pulse) and uses the identical DO-214AC/SMA package. The extended operating temperature range (-55°C ~ 175°C) provides additional thermal margin compared to the original part.

Q: What is the difference between SMAJ36A and SMAJ36A-TP?

A: Both parts are electrically identical with 36V/58.1V specifications. SMAJ36A-TP is supplied in Tape & Reel (TR) packaging and has an extended upper operating temperature limit (175°C vs. 150°C). SMAJ36A is available in standard packaging. Selection depends on production volume requirements and thermal operating conditions.

Q: Is SZ1SMA36AT3G suitable for non-automotive applications?

A: Yes. SZ1SMA36AT3G meets all electrical requirements for the CD214A-T36ALF replacement and is ROHS3 compliant. The automotive qualification (AEC-Q101) indicates higher reliability standards but does not restrict use in general-purpose applications. The lower temperature rating (-65°C minimum) provides additional margin for cold-environment operation.

Q: What is the significance of the 6.88A peak pulse current in TV04A360J-G versus 6.9A in other parts?

A: The 6.88A specification in TV04A360J-G represents a 0.02A difference from the 6.9A baseline, which is within typical manufacturing tolerance for TVS diodes in this class. This part remains electrically equivalent for the specified 400W peak pulse power rating and 58.1V clamping voltage.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts use DO-214AC/SMA surface-mount packaging, enabling direct board-level replacement without PCB redesign. SMAJ36A-TP is additionally specified with Tape & Reel (TR) supply format for automated assembly processes.

Q: Which substitute part has the best long-term availability?

A: SMAJ36A (MDD) and SZ1SMA36AT3G (Littelfuse) both have active product status with high inventory levels (7870 pcs and 9042 pcs respectively), indicating established manufacturing and supply chain support. Both are suitable for designs requiring long-term component availability.
