CD214B-T36CALF Equivalent & Substitute Parts
Part Overview
The CD214B-T36CALF 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 with a 36V reverse standoff voltage and 58.1V clamping voltage, delivering 10.3A peak pulse current in a compact SMB (DO-214AA) package. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation
Substitution for the CD214B-T36CALF is determined by the following critical electrical and mechanical parameters:
Primary Substitution Criteria:
- Voltage - Reverse Standoff (Typ): 36V
- Voltage - Clamping (Max) @ Ipp: 58.1V
- Current - Peak Pulse (10/1000µs): 10.3A minimum
- Package / Case: DO-214AA, SMB (surface mount)
- Bidirectional Channels: 1
- Power - Peak Pulse: 600W
Direct Equivalents maintain identical electrical specifications within the allowed tolerances for the voltage and current parameters listed above.
Similar Substitutes operate within the same voltage class but may have variations in clamping voltage (±5V range) and peak pulse current (±2A range). These parts are functionally compatible for general-purpose transient suppression applications where the exact clamping characteristics are not critical to circuit performance.

Engineering Selection Recommendations
Direct Equivalent: SMBJ36CA (MDD) is the primary direct equivalent. It maintains identical reverse standoff voltage (36V), breakdown voltage (40V), and clamping voltage (58.1V) specifications. Peak pulse current is 10.4A, within acceptable tolerance of the original 10.3A specification. The part is currently in active production status, ensuring long-term availability. ROHS3 compliance and MSL 1 rating match the original part requirements. Operating temperature range is -50°C to 150°C, which covers the original -55°C to 150°C range except at the lower extreme.
Similar Substitutes for Extended Voltage Range Applications: Vishay P6SMB series parts (P6SMB36CA-M3/52, P6SMB39CA-M3/52, P6SMB43CA-M3/52) offer active production status and extended operating temperature range (-65°C to 150°C). These parts are suitable where slightly different clamping voltages are acceptable within circuit design margins. P6SMB36CA-M3/52 provides the closest voltage match (49.9V clamping) with higher peak pulse current (12A). P6SMB43CA-M3/52 offers clamping voltage closest to the original (59.3V) with slightly lower peak pulse current (10.1A). All Vishay options include AEC-Q101 automotive qualification on select variants and ROHS3 compliance.
Frequently Asked Questions (FAQ)
Q: Can SMBJ36CA directly replace CD214B-T36CALF without circuit modification? A: Yes. SMBJ36CA maintains the same reverse standoff voltage (36V), breakdown voltage (40V), and clamping voltage (58.1V). Peak pulse current is 10.4A versus 10.3A, which is within normal component tolerance. Both are bidirectional zener diodes in DO-214AA SMB packages. The only consideration is the operating temperature range: SMBJ36CA operates to -50°C minimum versus -55°C for the original. Verify your application's minimum operating temperature requirement.
Q: What is the difference between direct equivalents and similar substitutes? A: Direct equivalents (SMBJ36CA) match all critical electrical parameters: reverse standoff voltage, breakdown voltage, and clamping voltage. Similar substitutes (Vishay P6SMB series) operate in the same voltage class but with different clamping voltages. For example, P6SMB36CA-M3/52 clamps at 49.9V instead of 58.1V. Use similar substitutes only when your circuit design can tolerate the voltage variation, typically in general-purpose transient suppression where exact clamping is not critical.
Q: Are all substitute parts available in the same SMB package? A: Yes. All listed substitutes use the DO-214AA SMB package, ensuring identical PCB footprint and mounting compatibility. Packaging variants (Tape & Box versus Tape & Reel) do not affect electrical performance or physical dimensions.
Q: What compliance certifications should I verify for my application? A: All listed parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. If your application requires automotive qualification, the Vishay P6SMB36CAHE3_A/H variant includes AEC-Q101 qualification, though it is classified as obsolete. For active production automotive-qualified options, consult Vishay's current P6SMB automotive product line.
Q: Can I use P6SMB39CA or P6SMB43CA if SMBJ36CA is unavailable? A: These are similar substitutes with different clamping voltages. P6SMB39CA clamps at 53.9V (4.2V lower than original), and P6SMB43CA clamps at 59.3V (1.2V higher than original). Use only if your circuit design allows this voltage variation. Both maintain 600W peak pulse power and are suitable for general-purpose transient suppression. Verify your specific circuit's transient voltage limits before substitution.
