TV06B351J-HF Equivalent & Substitute Parts

Part Overview

The TV06B351J-HF is a unidirectional Zener transient voltage suppressor (TVS) diode manufactured by Comchip Technology, designed for general-purpose overvoltage protection applications. This surface-mount component operates with a 350V reverse standoff voltage and provides 567V maximum clamping voltage at peak pulse current. The part is currently active in production and RoHS3 compliant, making it suitable for modern electronic circuit protection requirements.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified parameter range, ensuring reliable circuit protection without redesign.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TV06B351J-HF, SMBJ350A, and SMBJ350A-13-F—are active production components with identical RoHS3 compliance and MSL ratings. Selection between these parts may be based on:

• Availability: SMBJ350A (Meritek) offers 30,400 units in stock; SMBJ350A-13-F (Diodes Incorporated) offers 15,100 units; TV06B351J-HF (Comchip) offers 752 units.
• Peak pulse current capability: SMBJ350A-13-F provides 1.1A, exceeding the 1.06A specification of the other two parts, offering additional margin in high-stress applications.
• Manufacturer certification: All parts carry identical REACH and ECCN classifications (REACH Unaffected, EAR99).

Frequently Asked Questions (FAQ)

Q: Can SMBJ350A and SMBJ350A-13-F be used interchangeably with TV06B351J-HF?

A: Yes. All three parts meet the electrical specifications (350V standoff, 567V clamping, 600W peak power) and share identical DO-214AA (SMB) packaging and surface-mount configuration. The SMBJ350A-13-F variant provides slightly higher peak pulse current (1.1A vs. 1.06A), which is compatible with the original design.

Q: What is the significance of the different peak pulse current ratings?

A: TV06B351J-HF and SMBJ350A both specify 1.06A peak pulse current. SMBJ350A-13-F specifies 1.1A, representing approximately 3.8% higher current handling capability. This difference does not affect substitution compatibility; the higher rating provides additional design margin.

Q: Are there any temperature operating range differences?

A: SMBJ350A and SMBJ350A-13-F both specify -55°C to 150°C operating temperature. TV06B351J-HF does not provide an explicit operating temperature range in the supplied data. All parts are suitable for general industrial and commercial applications.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All three parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Which part should be selected for new designs?

A: Selection depends on availability and supply chain requirements. SMBJ350A (Meritek) and SMBJ350A-13-F (Diodes Incorporated) offer significantly higher stock levels and represent established alternatives. All parts are RoHS3 compliant and suitable for modern circuit protection applications.
