CD214B-T60CALF Equivalent & Substitute Parts

Part Overview

The CD214B-T60CALF is a transient voltage suppressor (TVS) diode manufactured by Bourns Inc., designed for general-purpose overvoltage protection in surface-mount applications. This bidirectional zener diode operates at 60V reverse standoff with a 96.8V maximum clamping voltage and 6.2A peak pulse current capability in a DO-214AA (SMB) package.

Substitute Part Grouping Explanation

Substitution for the CD214B-T60CALF is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

Voltage - Reverse Standoff: 60V (exact match required)
Voltage - Clamping (Max) @ Ipp: 96.8V (exact match required)
Current - Peak Pulse (10/1000µs): 6.2A (exact match required)
Power - Peak Pulse: 600W (exact match required)
Package / Case: DO-214AA, SMB (exact match required)
Bidirectional Channels: 1 (exact match required)
Mounting Type: Surface Mount (exact match required)

Direct Equivalents maintain all electrical specifications and package requirements, enabling drop-in replacement without circuit redesign.

Similar Parts share the same package and general application category but differ in voltage ratings or current specifications. These require circuit-level evaluation to confirm compatibility with the intended protection scheme.

Engineering Selection Recommendations

Direct Replacement (Electrical Equivalents):

SMBJ60CA (MDD), SMBJ60CA-TP (Micro Commercial Co), and TV06B600JB-HF (Comchip Technology) are direct electrical equivalents with identical voltage and current specifications. All three are active products with ROHS3 compliance. SMBJ60CA-TP offers the widest operating temperature range (-55°C to 175°C) and is recommended for applications requiring extended thermal performance. SMBJ60CA provides the highest inventory availability (125,100 units) for procurement continuity.

Alternative Voltage Ratings (Circuit Evaluation Required):

SMBJ51CA and SMBJ51CA-HR operate at 51V reverse standoff with 82.4V clamping voltage, suitable only for circuits designed for lower voltage protection thresholds. SMBJ58CA (58V standoff, 93.6V clamp) and TPSMB62CA (53V standoff, 85V clamp) provide intermediate voltage options. TPSMB68CA (58.1V standoff, 92V clamp) is qualified to AEC-Q101 automotive standards and operates across -65°C to 175°C, appropriate for automotive and extended-temperature applications.

All substitute parts maintain DO-214AA (SMB) package compatibility, single bidirectional channel configuration, 600W peak pulse power rating, and ROHS3 compliance with MSL 1 (unlimited moisture sensitivity).

Frequently Asked Questions (FAQ)

Q: Can SMBJ60CA directly replace CD214B-T60CALF without circuit modification?

A: Yes. SMBJ60CA matches all critical electrical parameters: 60V reverse standoff, 96.8V clamping voltage, 6.2A peak pulse current, and 600W power rating. The DO-214AA (SMB) package is identical. No circuit redesign is required.

Q: What is the difference between SMBJ60CA and SMBJ60CA-TP?

A: Both are 60V/96.8V/6.2A equivalents with identical electrical performance. SMBJ60CA-TP extends the operating temperature range to 175°C (versus 150°C for standard SMBJ60CA) and is manufactured by Micro Commercial Co rather than MDD. Select SMBJ60CA-TP for high-temperature applications.

Q: Can I use SMBJ51CA as a substitute?

A: SMBJ51CA is not a direct equivalent. It operates at 51V reverse standoff with 82.4V clamping voltage, compared to the CD214B-T60CALF's 60V/96.8V specification. Use SMBJ51CA only if your circuit is designed for 51V protection thresholds. Substitution requires circuit-level verification.

Q: Are the TPSMB series parts (TPSMB62CA, TPSMB68CA) suitable replacements?

A: TPSMB series parts differ in voltage ratings and are qualified to AEC-Q101 automotive standards. TPSMB62CA operates at 53V/85V and TPSMB68CA at 58.1V/92V. These are not direct equivalents and require circuit evaluation. Select these only if your application requires automotive qualification or extended temperature operation (-65°C to 175°C).

Q: Do all substitute parts have the same package footprint?

A: Yes. All listed substitutes use the DO-214AA (SMB) package with identical mechanical dimensions and land pattern. PCB layout changes are not required for direct electrical equivalents.

Q: What is the inventory status for each substitute?

A: SMBJ60CA (MDD) has the highest availability at 125,100 units. SMBJ60CA-TP provides 18,400 units. TV06B600JB-HF has limited stock at 940 units. For long-term procurement, SMBJ60CA is recommended due to superior availability.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed parts maintain ROHS3 compliance and MSL 1 (unlimited) moisture sensitivity rating, matching the original CD214B-T60CALF specifications.
