BZW04-14B-E3/73 Equivalent & Substitute Parts

Part Overview

The BZW04-14B-E3/73 is a bidirectional transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This component operates with a 13.6V reverse standoff voltage and provides 22.5V clamping protection at peak pulse current, making it suitable for general-purpose transient suppression applications. The device is housed in a DO-204AL (DO-41) axial through-hole package and is currently in active production status with ROHS3 compliance. Equivalent and substitute parts are identified based on matching electrical performance parameters and compatible package configurations.

Substitute Part Grouping Explanation

Substitute parts for the BZW04-14B-E3/73 are qualified based on the following electrical and mechanical criteria:

• Voltage - Reverse Standoff (Typ): 13.6V
• Voltage - Clamping (Max) @ Ipp: 22.5V
• Current - Peak Pulse (10/1000µs): 17.8A minimum
• Power - Peak Pulse: 400W
• Bidirectional Channels: 1
• Type: Zener TVS Diode
• Mounting Type: Through Hole
• Package / Case: DO-204AL (DO-41) or DO-204AC (DO-15) axial packages

Substitutes must maintain identical voltage specifications and equivalent or superior current handling capability. Package compatibility includes both DO-204AL and DO-204AC configurations, as both are axial through-hole formats suitable for equivalent circuit board integration.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain identical voltage specifications (13.6V standoff, 22.5V clamping) and equivalent power dissipation (400W peak pulse). Selection should be based on the following factors:

BZW04-14B-E3/73 (Vishay): Primary choice for applications requiring ROHS3 compliance and operating temperature range of -55°C to 175°C. DO-204AL package provides standard axial through-hole mounting.

P4KE16CA (Diotec): Suitable for applications where DO-204AC (DO-15) package compatibility is acceptable. Peak pulse current capability is 18.6A, exceeding the original specification. RoHS compliance status is not applicable; verify regulatory requirements for your application.

P4KE16CA-B (Littelfuse): Direct equivalent with ROHS3 compliance and identical operating temperature range (-55°C to 175°C). DO-204AL package matches the original form factor. Peak pulse current is 18.2A, meeting or exceeding original specifications.

Frequently Asked Questions (FAQ)

Q: Can P4KE16CA be used as a direct replacement for BZW04-14B-E3/73?

A: P4KE16CA meets all electrical specifications but uses a DO-204AC (DO-15) package instead of DO-204AL (DO-41). Both are axial through-hole formats with identical lead spacing and can be mounted on equivalent circuit board layouts. Verify package footprint compatibility with your PCB design before substitution.

Q: What is the difference between DO-204AL and DO-204AC packages?

A: Both are axial through-hole diode packages with identical electrical performance. DO-204AL (DO-41) and DO-204AC (DO-15) differ in physical dimensions and lead diameter. Confirm your PCB footprint specification before selecting a substitute.

Q: Is P4KE16CA-B a direct replacement for BZW04-14B-E3/73?

A: Yes. P4KE16CA-B matches the electrical specifications, operating temperature range, RoHS compliance status, and DO-204AL package configuration of the original part. Peak pulse current (18.2A) meets or exceeds the original specification (17.8A).

Q: Are all three parts suitable for ROHS3-compliant applications?

A: BZW04-14B-E3/73 and P4KE16CA-B are both ROHS3 compliant. P4KE16CA has not applicable RoHS status; verify compliance requirements with your regulatory or procurement department before use.

Q: What is the minimum operating temperature difference between these parts?

A: BZW04-14B-E3/73 and P4KE16CA-B operate from -55°C to 175°C. P4KE16CA operates from -50°C to 175°C, a 5°C difference at the lower temperature limit. For applications requiring -55°C operation, use BZW04-14B-E3/73 or P4KE16CA-B.
