DF01S1 Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DF01S1 is a single-phase bridge rectifier manufactured by onsemi, rated for 100 V peak reverse voltage and 1 A average rectified current in a 4-SDIP surface mount package. This component is classified as "Not For New Designs," indicating it has reached end-of-life status. Identifying equivalent and substitute parts is necessary to maintain design continuity, support existing production lines, and ensure component availability for legacy systems.

Substitute Part Grouping Explanation

Substitution of the DF01S1 is determined by strict equivalence across the following parameters:

Diode Type: Single Phase
Voltage - Peak Reverse (Max): 100 V
Current - Average Rectified (Io): 1 A
Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A
Operating Temperature Range: -55°C ~ 150°C (TJ)
Mounting Type: Surface Mount
Package / Case: 4-SMD, Gull Wing
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level (MSL): 1 (Unlimited)

All substitute parts listed meet these core electrical and mechanical specifications. Variations in reverse leakage current, packaging format (Tape & Reel vs. Cut Tape), and product status are noted but do not disqualify substitution when the primary parameters align.

Engineering Selection Recommendations

All listed substitute parts maintain active product status, ensuring long-term availability and continued manufacturer support. The DF01S1, classified as "Not For New Designs," should be replaced with an active equivalent for new applications.

DF01S-E3/77 and DF01SA-E3/77 (Vishay) offer the highest inventory levels (10200 and 3102 units respectively) and are direct variants of the DF01 base product family, providing design continuity with the original part.

DB102S (SMC Diode Solutions) provides substantial inventory (5300 units) and active status, making it suitable for high-volume production requirements.

DBLS102GHRDG (Taiwan Semiconductor Corporation) includes AEC-Q101 automotive qualification, appropriate for applications requiring automotive-grade components.

All substitute parts comply with ROHS3 and maintain MSL 1 (Unlimited) moisture sensitivity classification, matching the original DF01S1 specifications.

Frequently Asked Questions (FAQ)

Q: Can DF01S1 be directly replaced with any of these substitute parts?

A: Yes, all listed parts meet the core electrical specifications: 100 V peak reverse voltage, 1 A average rectified current, 1.1 V forward voltage at 1 A, and -55°C to 150°C operating temperature range. All are surface mount 4-SMD gull wing packages with ROHS3 compliance and MSL 1 rating.

Q: What is the difference between DF01S-E3/77 and DF01SA-E3/77?

A: Both are Vishay variants of the DF01 base product. DF01SA-E3/77 is packaged in Tape & Reel (TR) format with 3102 units in stock, while DF01S-E3/77 is supplied in Cut Tape (CT) & Digi-Reel® format with 10200 units in stock. Electrical specifications are identical.

Q: Are there any reverse leakage current differences that affect substitution?

A: Reverse leakage current varies across substitutes (2 µA to 10 µA @ 100 V) compared to the DF01S1 (3 µA @ 100 V). These variations remain within acceptable tolerances for standard bridge rectifier applications and do not disqualify substitution.

Q: Which substitute offers the best availability?

A: DF01S-E3/77 (Vishay) has the highest inventory at 10200 units, followed by DBLS102G (Taiwan Semiconductor Corporation) at 6400 units.

Q: Is DBLS102GHRDG suitable for automotive applications?

A: Yes, DBLS102GHRDG carries AEC-Q101 automotive qualification and is appropriate for automotive-grade component requirements.

Q: Do all substitutes maintain the same operating temperature range?

A: Yes, all substitute parts operate across the identical temperature range of -55°C to 150°C (TJ).
