TLP36CA Equivalent & Substitute Parts

Part Overview

The TLP36CA is a high-reliability transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose voltage clamping applications. This bidirectional zener TVS operates with a 36V reverse standoff voltage and provides peak pulse current handling of 87.8A with a maximum clamping voltage of 58.1V. The device is housed in a P600 axial through-hole package and maintains active product status with full RoHS3 and REACH compliance. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified parameter range.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLP36CA is permissible when the following electrical and mechanical criteria are met:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 36V
• Voltage - Clamping (Max) @ Ipp: 58.1V
• Bidirectional Channels: 1
• Mounting Type: Through Hole
• Operating Temperature Range: -55°C to 175°C minimum

Allowable Variation Parameters:

• Current - Peak Pulse (10/1000µs): Equal to or greater than 87.8A
• Power - Peak Pulse: Equal to or greater than 5000W
• Package / Case: Axial configuration (mechanical compatibility with through-hole PCB mounting)

The substitute part 6KPE36CAH meets all critical matching parameters and exceeds allowable variation thresholds with 113.6A peak pulse current and 6600W peak pulse power, maintaining full electrical and thermal performance equivalence.

Parameter Comparison

Engineering Selection Recommendations

The 6KPE36CAH from Eaton - Electronics Division is a qualified substitute for the TLP36CA based on electrical parameter equivalence and mechanical compatibility. Both devices maintain identical voltage clamping characteristics (58.1V maximum) and reverse standoff voltage (36V), ensuring functional interchangeability in circuit protection applications.

The substitute part provides enhanced current and power handling capabilities (113.6A and 6600W respectively versus 87.8A and 5000W), which represents a performance margin increase without introducing incompatibility. Both devices operate across the identical temperature range (-55°C to 175°C) and maintain REACH compliance status.

The 6KPE36CAH carries AEC-Q101 automotive qualification, indicating enhanced reliability screening and qualification testing. This certification provides additional assurance for applications requiring automotive-grade component reliability, though the original TLP36CA remains suitable for general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can the 6KPE36CAH replace the TLP36CA in existing designs?

A: Yes. The 6KPE36CAH maintains identical voltage clamping (58.1V) and reverse standoff (36V) specifications, with equivalent operating temperature range and bidirectional channel configuration. The substitute part exceeds the original specifications in peak pulse current and power handling, providing additional performance margin.

Q: Are there package compatibility concerns?

A: Both devices use axial through-hole packages suitable for PCB mounting. The P600 package designation for the TLP36CA and the axial configuration of the 6KPE36CAH are mechanically compatible for standard through-hole PCB applications.

Q: What is the significance of the higher current rating on the substitute part?

A: The 6KPE36CAH's 113.6A peak pulse current (versus 87.8A on the TLP36CA) represents a 29.4% increase in transient current handling capability. This higher rating does not affect circuit compatibility but provides additional margin for transient suppression in applications with variable surge conditions.

Q: Does the AEC-Q101 qualification on the 6KPE36CAH affect general-purpose applications?

A: No. AEC-Q101 qualification indicates enhanced reliability testing and is applicable to automotive and high-reliability applications. General-purpose applications are not negatively affected by this additional qualification; it represents a superset of standard reliability requirements.

Q: Are there compliance differences between the two parts?

A: Both parts maintain REACH Unaffected status and EAR99 ECCN classification. The TLP36CA specifies ROHS3 compliance; the 6KPE36CAH compliance status is not specified in the provided data. Verify RoHS compliance requirements for your specific application before substitution.
