5KP16AE3/TR13 Equivalent & Substitute Parts

Part Overview

The 5KP16AE3/TR13 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This component features a 16V reverse standoff voltage with a 26V maximum clamping voltage and peak pulse current rating of 192A at 5000W peak pulse power. The device is housed in a P600 axial through-hole package and is supplied in Tape & Reel (TR) packaging format.

The product maintains Active status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified based on matching or closely aligned electrical characteristics, including reverse standoff voltage, clamping voltage, peak pulse current, and power dissipation ratings, while maintaining compatibility with through-hole mounting applications.

Substitute Part Grouping Explanation

Substitution of the 5KP16AE3/TR13 is determined by alignment of critical electrical parameters: reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, and peak pulse power dissipation. All substitute parts identified maintain the same unidirectional zener diode topology with single-channel configuration and through-hole mounting.

Substitute parts are grouped into two categories:

Direct Electrical Equivalents (P600 Package): Parts maintaining identical or near-identical reverse standoff voltage (16V), breakdown voltage (17.8V minimum), clamping voltage (26V maximum), and peak pulse power (5000W) within the same P600 axial package form factor. These parts include 5KP16A-E3/54, 5KP16A, and SLD16U-017.

Similar Electrical Characteristics (Alternative Packages): Parts with comparable voltage ratings and clamping characteristics but housed in alternative through-hole packages (DO-201, DO-15, R-6). These include 1.5KE18A, LCE15A, LCE16A, LCE18A, P6KE18A, P6KE20A, and 5KP16A-TP. These alternatives present reduced peak pulse current and power dissipation ratings, making them suitable for lower-energy transient suppression applications.

Engineering Selection Recommendations

Direct Substitution (P600 Package, 5000W Rating):

The 5KP16A-E3/54 (Vishay General Semiconductor) provides direct electrical equivalence with identical voltage ratings and peak pulse specifications. This part is supplied in Cut Tape (CT) packaging with 8300 units in stock inventory.

The 5KP16A (Littelfuse Inc.) maintains equivalent electrical performance with marginally higher peak pulse current (196.2A versus 192A) and identical 5000W power dissipation. This part is supplied in Cut Tape (CT) packaging with 4747 units in stock.

The SLD16U-017 (Littelfuse Inc.) delivers equivalent electrical performance with AEC-Q101 automotive qualification and REACH-affected status. This part is supplied in Cut Tape (CT) packaging with 6049 units in stock and is suitable for automotive-grade applications.

Alternative Package Substitution (Reduced Power Rating):

The LCE16A (Littelfuse Inc.) matches the 16V reverse standoff and 26V clamping voltage specifications but operates at 1500W peak pulse power with 57A peak pulse current. This part is housed in DO-201 package and is suitable for lower-energy transient suppression circuits.

Lower Voltage Rating Alternatives:

The 1.5KE18A (Taiwan Semiconductor Corporation) and LCE15A (Littelfuse Inc.) provide similar voltage protection in the 15–18V range with reduced power dissipation (1500W) and peak pulse current (60–61A). These parts are suitable for applications with lower transient energy requirements.

All identified substitute parts maintain RoHS3 compliance, MSL 1 rating, and through-hole mounting compatibility. Product status is Active for all listed alternatives.

Frequently Asked Questions (FAQ)

Q: Can the 5KP16A-E3/54 directly replace the 5KP16AE3/TR13?

A: Yes. Both parts share identical electrical specifications: 16V reverse standoff voltage, 17.8V minimum breakdown voltage, 26V maximum clamping voltage, 192A peak pulse current, and 5000W peak pulse power. The primary difference is packaging format (Cut Tape versus Tape & Reel) and manufacturer (Vishay versus Microchip). Electrical performance and thermal characteristics are equivalent.

Q: What is the difference between the 5KP16A and SLD16U-017?

A: Both parts deliver equivalent electrical performance in the P600 package with 5000W peak pulse power and 16V reverse standoff voltage. The SLD16U-017 carries AEC-Q101 automotive qualification and is designated for automotive-grade applications. The 5KP16A is a general-purpose variant without automotive qualification. Selection depends on application requirements.

Q: Can I use the LCE16A as a substitute for the 5KP16AE3/TR13?

A: The LCE16A matches the voltage specifications (16V reverse standoff, 26V clamping) but operates at significantly reduced power dissipation (1500W versus 5000W) and peak pulse current (57A versus 192A). Substitution is valid only for applications with lower transient energy requirements. High-energy transient suppression applications require the full 5000W rating.

Q: What packaging differences exist among the substitute parts?

A: The 5KP16AE3/TR13, 5KP16A-E3/54, 5KP16A, and SLD16U-017 are all housed in P600 axial through-hole packages with identical mechanical form factors. The 1.5KE18A, LCE15A, LCE16A, and LCE18A use DO-201 (DO-27) axial packages. The P6KE18A and P6KE20A use DO-15 (DO-204AC) packages. The 5KP16A-TP uses an R-6 package. All are through-hole mounted; physical board layout compatibility must be verified before substitution.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts carry RoHS3 compliance certification. The SLD16U-017 is REACH-affected; all other parts are REACH-unaffected. Compliance status should be verified against specific procurement requirements.

Q: What is the operating temperature range for substitute parts?

A: The 5KP16AE3/TR13 and all P600-package substitutes (5KP16A-E3/54, 5KP16A, SLD16U-017, 5KP16A-TP) operate across -55°C to 175°C junction temperature. The DO-201 package variants (1.5KE18A, LCE15A, LCE16A, LCE18A) also operate across -55°C to 175°C. The P6KE18A and P6KE20A operate across -50°C to 175°C, with a 5°C lower minimum temperature limit.

Q: Which substitute offers the highest inventory availability?

A: The P6KE18A (Fairchild Semiconductor) offers the highest inventory with 45,200 units in stock. However, this part operates at 600W peak pulse power and 25A peak pulse current, significantly below the 5KP16AE3/TR13 specifications. For equivalent 5000W performance, the SLD16U-017 offers the highest inventory (6049 units) among direct electrical equivalents.
