MP6KE100AE3 Equivalent & Substitute Parts

Part Overview

The MP6KE100AE3 is a unidirectional Zener transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose transient voltage protection applications. This through-hole component features a 85.5V reverse standoff voltage with a 137V maximum clamping voltage and 4.4A peak pulse current capability. The device is qualified to MIL-PRF-19500 military standards and maintains an active product status. Substitute parts are identified to provide equivalent electrical performance and functional compatibility for applications requiring TVS diode protection with comparable voltage and current ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MP6KE100AE3 is determined by equivalence in the following critical electrical parameters:

• Voltage - Clamping (Max) @ Ipp: 137V (identical across all qualified substitutes)
• Current - Peak Pulse (10/1000µs): 4.4A (identical across all qualified substitutes)
• Power - Peak Pulse: 600W (identical across all qualified substitutes)
• Voltage - Breakdown (Min): 95V (identical across all qualified substitutes)
• Type: Zener, unidirectional configuration
• Mounting Type: Through Hole
• Base Product Number: P6KE100 (common designation)

The P6KE100A from Fairchild Semiconductor qualifies as an equivalent substitute based on matching electrical performance parameters. Variations in reverse standoff voltage (85.5V vs. 100V) and operating temperature range (-65°C to 150°C vs. -55°C to 150°C) do not preclude substitution when the primary clamping and current characteristics are identical. Package differences (T-18 vs. DO-15) represent mechanical variations that must be evaluated against circuit board layout and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the MP6KE100AE3 and P6KE100A maintain active product status and are suitable for general-purpose transient voltage suppression applications. The MP6KE100AE3 carries military qualification under MIL-PRF-19500, which may be required for defense or aerospace applications. The P6KE100A provides equivalent electrical performance with higher inventory availability (18,855 pcs vs. 720 pcs).

Selection between these devices should be based on:

1. Qualification Requirements: If MIL-PRF-19500 compliance is mandatory, the MP6KE100AE3 is the required choice.
2. Temperature Operating Range: The MP6KE100AE3 supports operation to -65°C, while the P6KE100A operates to -55°C minimum. Applications requiring extended low-temperature performance require the MP6KE100AE3.
3. Package Compatibility: The T-18 package (MP6KE100AE3) and DO-15 package (P6KE100A) have different physical dimensions and lead configurations. Circuit board layout and mechanical constraints determine package suitability.
4. Supply Chain Considerations: The P6KE100A offers significantly higher stock availability for non-military applications.

Frequently Asked Questions (FAQ)

Q: Can the P6KE100A directly replace the MP6KE100AE3 in all applications?

A: The P6KE100A provides equivalent electrical performance for transient voltage suppression. However, package differences (T-18 vs. DO-15) require physical compatibility verification. Military applications requiring MIL-PRF-19500 qualification must use the MP6KE100AE3.

Q: What is the significance of the different reverse standoff voltages (85.5V vs. 100V)?

A: Both devices share identical breakdown voltage (95V minimum) and clamping voltage (137V maximum). The reverse standoff voltage represents the maximum voltage the device sustains without conduction during normal operation. The higher standoff voltage of the P6KE100A (100V) provides a wider safety margin in applications with nominal operating voltages near 85.5V.

Q: Are the T-18 and DO-15 packages interchangeable?

A: No. T-18 and DO-15 are distinct through-hole axial packages with different physical dimensions and lead spacing. PCB layout modifications are required to accommodate package substitution.

Q: Does the operating temperature range difference affect substitution suitability?

A: The MP6KE100AE3 supports operation to -65°C, while the P6KE100A operates to -55°C minimum. Applications requiring operation below -55°C must use the MP6KE100AE3. For applications within the -55°C to 150°C range, both devices are suitable.

Q: What is the base product number significance?

A: Both devices share the base product number P6KE100, indicating they belong to the same product family with equivalent electrical specifications. Suffixes (A, AE3) denote manufacturer-specific variants, packaging, and qualification levels.

Q: Are there RoHS compliance differences between these devices?

A: The MP6KE100AE3 is RoHS non-compliant. Compliance status for the P6KE100A was not provided in the available data. Applications subject to RoHS requirements require verification of the specific substitute part's compliance status.
