CD214A-T5.0ALF Equivalent & Substitute Parts
Part Overview
The CD214A-T5.0ALF is a unidirectional Zener transient voltage suppressor (TVS) diode manufactured by Bourns Inc., designed for general-purpose overvoltage protection in surface-mount applications. This component features a 5V reverse standoff voltage, 9.2V maximum clamping voltage, and 44.6A peak pulse current capability in the DO-214AC (SMA) package. The part is classified as obsolete, necessitating identification of active equivalent and substitute components to maintain design continuity and ensure supply chain availability for new production and field replacements.

Substitute Part Grouping Explanation
Substitution of the CD214A-T5.0ALF is determined by strict equivalence across the following critical parameters:
- Voltage - Reverse Standoff (Typ): 5V
- Voltage - Breakdown (Min): 6.4V
- Voltage - Clamping (Max) @ Ipp: 9.2V
- Current - Peak Pulse (10/1000µs): 44.6A
- Power - Peak Pulse: 400W
- Package / Case: DO-214AC (SMA)
- Type: Unidirectional Zener
- RoHS3 Compliance
Substitute parts are categorized into two groups:
Direct Equivalents: Parts meeting all critical electrical parameters (5V standoff, 9.2V clamping, 44.6A peak pulse, 400W power rating) with identical package specifications and active product status.
Similar Alternatives: Parts with matching voltage standoff and breakdown specifications but differing in clamping voltage, peak pulse current, or power rating. These require application-level verification to confirm suitability for the intended circuit protection function.

Engineering Selection Recommendations
Direct Replacement Priority:
SMAJ5.0A-TP (Micro Commercial Co) and TV04A5V0J-G or TV04A5V0J-HF (Comchip Technology) are the primary direct equivalents. All three parts match the CD214A-T5.0ALF across voltage standoff, clamping voltage, peak pulse current, and power rating specifications. SMAJ5.0A-TP extends the upper operating temperature to 175°C compared to the original 150°C specification. TV04A5V0J-G and TV04A5V0J-HF maintain the original temperature range and offer peak pulse current of 43.48A, functionally equivalent to the 44.6A specification.
SMAJ5.0A (MDD) provides direct electrical equivalence but operates at a minimum temperature of -50°C versus the original -55°C lower limit. This part is suitable for applications where the lower temperature boundary is not critical.
Alternative Consideration:
SM4T6V7AY, SMA6J5.0A-TR, and SMAJ5.0A-TR (all STMicroelectronics) feature higher clamping voltages (13.4V) and significantly higher peak pulse currents. These parts are suitable only for applications where the circuit design can tolerate the elevated clamping voltage and where the enhanced current handling capability provides system-level benefit. These alternatives require circuit-level analysis to confirm compatibility.
All recommended substitutes maintain RoHS3 compliance, MSL Level 1 rating, and DO-214AC (SMA) package compatibility with the original design.
Frequently Asked Questions (FAQ)
Q: Can SMAJ5.0A-TP be used as a direct replacement for CD214A-T5.0ALF?
A: Yes. SMAJ5.0A-TP meets all critical electrical specifications: 5V reverse standoff, 9.2V clamping voltage, 44.6A peak pulse current, and 400W power rating. The part is in active production status and uses the same DO-214AC (SMA) package. The extended operating temperature range (-55 to 175°C) provides additional margin compared to the original specification.
Q: What is the difference between direct equivalents and similar alternatives?
A: Direct equivalents (SMAJ5.0A-TP, TV04A5V0J-G, TV04A5V0J-HF) match the CD214A-T5.0ALF across all critical protection parameters. Similar alternatives (SM4T6V7AY, SMA6J5.0A-TR, SMAJ5.0A-TR) maintain the 5V standoff voltage but feature higher clamping voltages (13.4V) and greater peak pulse current capability. Similar alternatives require application verification to ensure the higher clamping voltage does not exceed circuit protection thresholds.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All substitute parts listed in this reference meet RoHS3 compliance requirements and maintain MSL Level 1 (unlimited moisture sensitivity) classification, consistent with the original CD214A-T5.0ALF specification.
Q: Does the package type differ among substitute options?
A: No. All substitute parts use the DO-214AC (SMA) surface-mount package, ensuring mechanical and electrical compatibility with existing PCB layouts designed for the CD214A-T5.0ALF.
Q: Why is the CD214A-T5.0ALF classified as obsolete?
A: Obsolete status indicates the part is no longer manufactured by Bourns Inc. and is not available through standard distribution channels for new production orders. Existing inventory may be available through secondary sources, but direct equivalents in active production status are recommended for new designs and long-term supply assurance.
Q: Can TV04A5V0J-G and TV04A5V0J-HF be used interchangeably?
A: Yes. Both parts are manufactured by Comchip Technology and share identical electrical specifications (5V standoff, 9.2V clamping, 43.48A peak pulse, 400W power). The designation difference (-G versus -HF) reflects packaging or tape configuration variants. Verify tape format compatibility with assembly equipment before selection.
