P6KE16A-B Equivalent & Substitute Parts

Part Overview

The P6KE16A-B is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose transient voltage protection applications. This through-hole component operates with a reverse standoff voltage of 13.6V and provides clamping protection at 22.5V maximum. The part is currently in active production status with 686 units available in bulk packaging. Equivalent and substitute parts are identified when they maintain identical or compatible electrical and mechanical specifications within the allowed parameter tolerances for this TVS diode category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P6KE16A-B is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 13.6V
• Voltage - Breakdown (Min): 15.2V
• Voltage - Clamping (Max) @ Ipp: 22.5V
• Current - Peak Pulse (10/1000µs): within acceptable tolerance
• Power - Peak Pulse: 600W minimum
• Package / Case: DO-204AC (DO-15) axial through-hole
• Type: Zener unidirectional TVS diode
• Unidirectional Channels: 1

The P6KE16A manufactured by Diotec Semiconductor meets all substitution criteria. This part maintains identical voltage specifications, equivalent peak pulse current (28A vs. 27.1A), matching power rating, and compatible through-hole packaging. Both parts are RoHS3 compliant and rated for general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

The P6KE16A manufactured by Diotec Semiconductor is a direct substitute for the P6KE16A-B. Both components are active-status products with RoHS3 compliance certification. The Diotec variant provides equivalent electrical performance with a marginally higher peak pulse current rating (28A vs. 27.1A), which presents no compatibility concerns for applications designed around the original specification.

The primary distinction is the operating temperature lower limit: the Diotec part is rated to -50°C versus -55°C for the Littelfuse original. Applications requiring operation below -50°C must use the Littelfuse P6KE16A-B. For general-purpose transient voltage suppression within the -50 to 175°C range, the Diotec P6KE16A is functionally equivalent.

Packaging differs between bulk (Littelfuse) and strip (Diotec) formats, which may affect procurement and assembly workflows but does not impact electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Diotec P6KE16A replace the Littelfuse P6KE16A-B in all applications?

A: Yes, for applications operating within the -50 to 175°C temperature range. If your circuit requires operation below -50°C, the Littelfuse original is required.

Q: Are the voltage specifications identical between these parts?

A: Yes. Both parts maintain 13.6V reverse standoff voltage, 15.2V minimum breakdown voltage, and 22.5V maximum clamping voltage. They are electrically equivalent for voltage protection.

Q: Does the higher peak pulse current (28A vs. 27.1A) on the Diotec part affect compatibility?

A: No. A higher current rating is compatible with applications designed for the lower rating. The Diotec part provides equal or superior performance in this parameter.

Q: What is the difference between bulk and strip packaging?

A: Bulk packaging typically contains loose components, while strip packaging contains components on a carrier tape. Both formats contain identical components; the difference is in handling and assembly convenience.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the Littelfuse P6KE16A-B and Diotec P6KE16A are RoHS3 compliant, meeting environmental and regulatory requirements.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes. Both parts use identical DO-204AC (DO-15) axial through-hole packaging and have the same pin configuration, allowing direct substitution in PCB designs.
