TB0640L-13 Equivalent & Substitute Parts

Part Overview

The TB0640L-13 is a 58V off-state thyristor transient voltage suppressor (TVS) in DO-214AA (SMB) surface mount packaging, rated for 150A peak pulse current at 8/20µs. This component is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

The TB0640L-13-F qualifies as a direct substitute based on identical electrical specifications across all critical parameters: breakover voltage (77V), off-state voltage (58V), on-state voltage (4.6V), peak pulse current ratings (150A at 8/20µs and 30A at 10/1000µs), hold current (150mA), element count (1), capacitance (100pF), and package type (DO-214AA, SMB). The substitution is valid across all allowed electrical and mechanical parameters for this TVS thyristor category.

Parameter Comparison

Engineering Selection Recommendations

The TB0640L-13-F is the direct equivalent for TB0640L-13 applications. The primary distinction is product status: TB0640L-13 is discontinued, while TB0640L-13-F is active. Additionally, TB0640L-13-F carries ROHS3 compliance, whereas TB0640L-13 is RoHS non-compliant. Both parts share identical electrical and mechanical specifications. The packaging difference (Cut Tape versus Tape & Reel) reflects supply format only and does not affect component functionality or circuit performance.

Frequently Asked Questions (FAQ)

Q: Can TB0640L-13-F replace TB0640L-13 in existing designs? A: Yes. All electrical parameters, mechanical dimensions, and package specifications are identical. Direct substitution is valid.

Q: What is the difference between Cut Tape and Tape & Reel packaging? A: Both formats contain the same component. Cut Tape is supplied in smaller quantities on individual tape segments. Tape & Reel is supplied in continuous reel format for automated assembly. The component itself is unchanged.

Q: Does the RoHS compliance difference affect substitution? A: No. RoHS compliance is a material composition specification. TB0640L-13-F's ROHS3 compliance indicates it meets current environmental standards. This does not alter electrical or mechanical performance.

Q: Are there any circuit design considerations when switching from TB0640L-13 to TB0640L-13-F? A: No. Identical voltage ratings, current ratings, and capacitance specifications ensure equivalent circuit behavior. No design modifications are required.

Q: Why is TB0640L-13 discontinued? A: Product discontinuation is a manufacturer decision. TB0640L-13-F remains in active production and provides full functional equivalence.
