BAY135-TAP Equivalent & Substitute Parts

Part Overview

The BAY135-TAP is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This through-hole component operates at 125 V DC reverse voltage with 200 mA average rectified current in a DO-35 (DO-204AH) axial package. The device is classified as a small-signal diode with standard recovery characteristics and is actively produced and widely stocked. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to component availability, supply chain considerations, or design flexibility within the specified parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BAY135-TAP are qualified based on the following electrical and mechanical criteria:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) rating must equal or exceed 125 V
• Current - Average Rectified (Io) must equal or exceed 200 mA
• Mounting type must be Through Hole
• Package must be compatible with DO-204AH, DO-35, or Axial configurations
• Operating temperature range must support 175°C maximum junction temperature
• RoHS3 compliance and active product status required

Substitution Groups:

Group 1: Direct Electrical Equivalents with Enhanced Ratings Parts BAV20,113, BAV20,133, and BAV20,143 operate at 150 V DC reverse voltage and 250 mA average rectified current. These exceed the BAY135-TAP minimum requirements and are classified as fast recovery diodes (≤500ns, >200mA). All three maintain the same DO-35 axial package configuration and are RoHS3 compliant with active product status.

Group 2: Matched Electrical Specification Part BAY72TR from Fairchild Semiconductor matches the BAY135-TAP electrical specifications exactly: 125 V DC reverse voltage and 200 mA average rectified current. This part maintains identical package configuration (DO-35, DO-204AH) and operating temperature range, with active product status and RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

BAY72TR (Fairchild Semiconductor)

The BAY72TR provides direct electrical and mechanical equivalence to the BAY135-TAP. Both devices operate at identical voltage and current ratings (125 V, 200 mA) with matching DO-35 axial package configuration. The BAY72TR is actively produced with substantial inventory availability (80,843 pcs). This part is the preferred substitute when exact specification matching is required and component interchangeability is the primary objective.

BAV20,113, BAV20,133, BAV20,143 (Nexperia/NXP)

The BAV20 series parts (BAV20,113, BAV20,133, BAV20,143) operate at elevated voltage and current ratings (150 V, 250 mA) compared to the BAY135-TAP (125 V, 200 mA). These parts are classified as fast recovery diodes with specified reverse recovery time of 50 ns, whereas the BAY135-TAP is classified as small-signal with unspecified recovery time. All three BAV20 variants maintain DO-35 axial package compatibility and active product status. These parts are suitable for applications where higher voltage and current margins are acceptable and fast recovery characteristics are beneficial or neutral to circuit operation. Inventory availability is substantial across all three variants (40,300 to 223,049 pcs).

Compliance and Regulatory Status

All substitute parts maintain RoHS3 compliance status and active product classification. The BAY135-TAP, BAV20,113, and BAV20,143 carry explicit ROHS3 Compliant designation. All parts are classified under ECCN EAR99 and HTSUS 8541.10.0070. Moisture sensitivity level is 1 (Unlimited) for all parts where specified.

Frequently Asked Questions (FAQ)

Q: Can BAV20,113, BAV20,133, or BAV20,143 be used as direct replacements for BAY135-TAP?

A: Yes. The BAV20 series parts exceed the electrical requirements of the BAY135-TAP. The BAV20 variants operate at 150 V and 250 mA, which are higher than the BAY135-TAP ratings of 125 V and 200 mA. All parts share identical DO-35 axial package configuration and 175°C maximum junction temperature. The primary difference is that BAV20 parts are classified as fast recovery diodes (50 ns reverse recovery time) versus the BAY135-TAP small-signal classification. This difference does not prevent substitution in applications designed for the BAY135-TAP.

Q: What is the difference between BAV20,113, BAV20,133, and BAV20,143?

A: These three parts have identical electrical specifications (150 V, 250 mA, 50 ns reverse recovery time) and package configuration (DO-35 axial). The differences are in packaging format and manufacturer designation. BAV20,113 and BAV20,143 are supplied in Cut Tape (CT) packaging by Nexperia USA Inc., while BAV20,133 is supplied in Bulk packaging by NXP USA Inc. Selection between these three variants depends on packaging requirements and inventory availability rather than electrical performance.

Q: Is BAY72TR electrically identical to BAY135-TAP?

A: Yes. The BAY72TR matches the BAY135-TAP in all primary electrical specifications: 125 V DC reverse voltage, 200 mA average rectified current, 1 V forward voltage drop, and 175°C maximum junction temperature. Both are classified as small-signal diodes and share the DO-35 axial package configuration. The BAY72TR is the closest electrical equivalent and is suitable for direct substitution.

Q: Can I use a BAV20 part in a circuit designed for BAY135-TAP?

A: Yes. The BAV20 series parts have higher voltage and current ratings than required by the BAY135-TAP specification. Higher-rated components operate within their design margins when used in applications rated for lower specifications. The fast recovery characteristic of BAV20 parts (50 ns) does not create incompatibility with circuits designed for small-signal diodes. Substitution is valid from an electrical standpoint.

Q: What packaging options are available for substitute parts?

A: All substitute parts are supplied in DO-35 axial through-hole package configuration, matching the BAY135-TAP. Packaging format variations exist at the supplier level: BAV20,113 and BAV20,143 are available in Cut Tape (CT) format, BAV20,133 is available in Bulk format, and BAY72TR is available in Bulk format. These format differences do not affect electrical compatibility or mechanical fit.

Q: Are all substitute parts RoHS3 compliant?

A: BAY135-TAP, BAV20,113, and BAV20,143 carry explicit ROHS3 Compliant designation. BAV20,133 and BAY72TR do not have RoHS status specified in the provided data. For applications requiring verified RoHS3 compliance, BAY135-TAP, BAV20,113, or BAV20,143 are the appropriate selections.

Q: What is the inventory status of substitute parts?

A: All substitute parts are actively produced with substantial inventory availability. BAY72TR has the highest inventory (80,843 pcs), followed by BAV20,133 (223,049 pcs), BAV20,113 (40,300 pcs), and BAV20,143 (5,551 pcs). The BAY135-TAP itself has 6,090 pcs in stock.
