1N6375 Transient Voltage Suppressor (TVS) Diode - Equivalent & Substitute Parts

Part Overview

The 1N6375 is a unidirectional Zener-type transient voltage suppressor manufactured by onsemi, designed for general-purpose overvoltage protection in through-hole axial configurations. This component features a 10V reverse standoff voltage with a 16.7V maximum clamping voltage and 1500W peak pulse power rating. The 1N6375 is classified as obsolete, making identification of functionally equivalent active alternatives essential for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1N6375 is determined by the following critical electrical and mechanical parameters:

• Voltage Rating Match: Reverse standoff voltage of 10V and clamping voltage in the 16.7V–17V range
• Power Dissipation: Peak pulse power rating of 1500W (1.5kW)
• Package Compatibility: Through-hole axial mounting in DO-201 series packages
• Unidirectional Protection: Single-channel Zener-type TVS diode
• Temperature Range: Operating temperature capability from -55°C to 175°C minimum

The substitute parts LCE10A and LCE10A-TP meet these criteria and are classified as active products, providing direct functional equivalence to the obsolete 1N6375.

Parameter Comparison

Engineering Selection Recommendations

LCE10A (Littelfuse) is the primary substitute for the 1N6375. This part maintains electrical equivalence across all critical parameters, operates within the required voltage and power specifications, and is actively manufactured. The LCE10A carries ROHS3 compliance, meeting modern regulatory requirements that the obsolete 1N6375 does not satisfy.

LCE10A-TP (Micro Commercial Co) provides an alternative source for the same electrical specification. This variant is also actively produced and suitable for applications requiring the 10V/17V TVS diode function. Package designation DO-201AE is mechanically compatible with standard through-hole axial mounting.

Both substitute parts support the full operating temperature range required for the application, with the exception that the 1N6375 specifies a lower minimum temperature (-65°C versus -55°C). Applications requiring operation below -55°C should verify thermal performance against specific design requirements.

Frequently Asked Questions (FAQ)

Q: Can the LCE10A directly replace the 1N6375 in existing designs?

A: Yes. The LCE10A provides electrical equivalence across voltage rating, power dissipation, and package type. Both are through-hole axial TVS diodes with 10V standoff and approximately 17V clamping voltage. Physical dimensions and pin configuration are compatible with DO-201 series footprints.

Q: What is the difference between LCE10A and LCE10A-TP?

A: Both parts meet the same electrical specifications for 10V standoff voltage, 17V clamping voltage, and 1500W peak pulse power. The primary differences are manufacturer (Littelfuse versus Micro Commercial Co) and packaging format (Cut Tape versus Bulk). Electrical performance and through-hole axial mounting are identical.

Q: Does the operating temperature difference between 1N6375 and the substitutes affect compatibility?

A: The 1N6375 specifies -65°C minimum junction temperature, while LCE10A and LCE10A-TP specify -55°C minimum. For applications operating above -55°C, the substitutes are fully compatible. Applications requiring operation below -55°C must verify that the substitute parts meet thermal performance requirements at the lower temperature.

Q: Are the substitute parts RoHS compliant?

A: LCE10A is ROHS3 compliant. LCE10A-TP RoHS status is not specified in available documentation. The 1N6375 is RoHS non-compliant. For applications subject to RoHS requirements, LCE10A is the recommended choice.

Q: What package variants are available for the substitutes?

A: LCE10A is available in DO-201AA and DO-27 axial packages. LCE10A-TP is available in DO-201AE axial package. All variants maintain through-hole axial mounting compatibility with the original 1N6375 DO-201AD package.
