ATV15C201JB-HF Equivalent & Substitute Parts

Part Overview

The ATV15C201JB-HF is a bidirectional Transient Voltage Suppressor (TVS) diode manufactured by Comchip Technology, designed for surface mount applications in the DO-214AB (SMC) package. This component provides transient overvoltage protection with a 200V reverse standoff voltage and 324V maximum clamping voltage. The part is actively produced and carries AEC-Q101 automotive qualification, making it suitable for automotive and industrial protection circuits. Identifying equivalent substitute parts ensures design flexibility, supply chain continuity, and access to alternative inventory sources while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ATV15C201JB-HF are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Electrical Parameters (Must Match):

• Voltage - Reverse Standoff (Typ): 200V
• Voltage - Breakdown (Min): 224V
• Voltage - Clamping (Max) @ Ipp: 324V
• Current - Peak Pulse (10/1000µs): 4.6A
• Power - Peak Pulse: 1500W

Mechanical Parameters (Must Match):

• Package / Case: DO-214AB (SMC)
• Mounting Type: Surface Mount
• Bidirectional Channels: 1

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Operating Temperature Range: -55°C to 150°C

The SMCJ200CA from Good-Ark Semiconductor meets all specified electrical, mechanical, and compliance requirements and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the ATV15C201JB-HF and SMCJ200CA are active production parts with identical electrical specifications and mechanical packaging. Selection between these parts should be based on:

Availability and Lead Time: The SMCJ200CA currently has higher inventory availability (1830 pcs) compared to the ATV15C201JB-HF (795 pcs), making it suitable for applications requiring expedited procurement.

Compliance and Qualification: The ATV15C201JB-HF carries AEC-Q101 automotive qualification, making it the preferred choice for automotive applications requiring formal qualification documentation. The SMCJ200CA meets equivalent electrical and environmental specifications but does not specify automotive qualification status in the provided data.

Supply Chain Strategy: For non-automotive applications or where supply chain redundancy is required, either part provides equivalent performance. For automotive designs, the ATV15C201JB-HF is the primary selection with SMCJ200CA as a secondary option pending qualification review.

Frequently Asked Questions (FAQ)

Q: Can SMCJ200CA be used as a direct replacement for ATV15C201JB-HF in automotive applications?

A: Both parts share identical electrical parameters (200V standoff, 324V clamping, 4.6A peak pulse, 1500W power rating) and mechanical packaging (DO-214AB SMC). However, the ATV15C201JB-HF carries AEC-Q101 automotive qualification. Use of SMCJ200CA in automotive designs requires verification of qualification requirements for your specific application.

Q: Are there packaging differences between these parts?

A: Both parts use the DO-214AB (SMC) surface mount package. The ATV15C201JB-HF is supplied in Tape & Reel (TR) packaging, while SMCJ200CA is available in Cut Tape (CT) and Digi-Reel® formats. All formats are compatible with standard surface mount assembly equipment.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution is determined by matching: Reverse Standoff Voltage (200V), Breakdown Voltage (224V minimum), Clamping Voltage (324V maximum), Peak Pulse Current (4.6A), and Peak Pulse Power (1500W). Any deviation in these parameters disqualifies a part as a direct substitute.

Q: Do both parts meet environmental and compliance standards?

A: Both parts are ROHS3 compliant, REACH unaffected, and rated for -55°C to 150°C operating temperature. Both have MSL 1 (unlimited moisture sensitivity level), indicating no special storage requirements.

Q: Which part should be selected for new designs?

A: For automotive applications, select ATV15C201JB-HF due to AEC-Q101 qualification. For general industrial applications, either part is suitable based on availability and lead time requirements.
