TV06B401JB-HF Equivalent & Substitute Parts

Part Overview

The TV06B401JB-HF is a Transient Voltage Suppressor (TVS) diode manufactured by Comchip Technology, designed for general-purpose overvoltage protection applications. This bidirectional zener diode operates at 400V reverse standoff voltage with a 648V maximum clamping voltage and 930mA peak pulse current capability in a surface-mount DO-214AA (SMB) package. The component is Active status and RoHS3 compliant. Substitute parts are identified to provide equivalent electrical performance and mechanical compatibility for applications requiring TVS protection in the 400V class.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TV06B401JB-HF are qualified based on the following electrical and mechanical parameters:

• Voltage - Reverse Standoff: 400V (identical)
• Voltage - Breakdown (Min): 447V (identical)
• Voltage - Clamping (Max) @ Ipp: 648V (identical)
• Current - Peak Pulse (10/1000µs): 900–930mA (within tolerance)
• Power - Peak Pulse: 600W (identical)
• Package / Case: DO-214AA, SMB (identical)
• Mounting Type: Surface Mount (identical)
• Type: Zener, Bidirectional (identical)
• RoHS Status: ROHS3 Compliant (identical)

The SMBJ400CA from Good-Ark Semiconductor meets all critical electrical specifications and mechanical requirements, with peak pulse current of 900mA representing a 3.2% variance from the original 930mA specification, which remains within acceptable operating margins for general-purpose TVS applications.

Parameter Comparison

Engineering Selection Recommendations

Both the TV06B401JB-HF and SMBJ400CA are Active status components with ROHS3 compliance and REACH unaffected status. The SMBJ400CA provides equivalent electrical performance across all critical parameters with a minor 30mA reduction in peak pulse current (900mA vs. 930mA), representing a 3.2% variance. Both components are packaged identically in DO-214AA (SMB) surface-mount format with MSL rating 1 (Unlimited), ensuring compatibility in standard PCB assembly processes. The SMBJ400CA offers significantly higher inventory availability (59,400 pcs vs. 932 pcs), making it a practical alternative for production applications requiring sustained supply.

Frequently Asked Questions (FAQ)

Q: Can the SMBJ400CA directly replace the TV06B401JB-HF in existing designs?

A: Yes. Both components share identical voltage ratings (400V standoff, 447V breakdown, 648V clamping), identical power dissipation (600W peak pulse), and identical packaging (DO-214AA, SMB). The 30mA difference in peak pulse current (900mA vs. 930mA) represents a 3.2% variance and does not affect functional compatibility in general-purpose TVS applications.

Q: Are there any package or mounting differences between these parts?

A: No. Both the TV06B401JB-HF and SMBJ400CA use the DO-214AA (SMB) surface-mount package with identical pinout and footprint. No PCB layout modifications are required for substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (Unlimited). They meet identical environmental and regulatory requirements.

Q: What is the significance of the 30mA peak pulse current difference?

A: The SMBJ400CA operates at 900mA peak pulse current compared to the TV06B401JB-HF at 930mA. This 3.2% variance remains within acceptable operating margins for general-purpose transient voltage suppression and does not compromise protection performance in standard applications.

Q: Which part should be selected for new designs?

A: Selection should be based on availability and supply chain requirements. The SMBJ400CA offers substantially higher inventory (59,400 pcs) compared to the TV06B401JB-HF (932 pcs), making it the preferred choice for production applications requiring sustained component supply.
