ABS10-G Bridge Rectifier Single Phase 1 kV 1 A Equivalent & Substitute Parts
Part Overview
The ABS10-G is a single-phase bridge rectifier manufactured by Comchip Technology, rated for 1 kV peak reverse voltage and 1 A average rectified current in a 4-SMD surface mount package. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. Substitute parts must maintain electrical performance across voltage, current, and thermal specifications while accommodating packaging and sourcing constraints.

Substitute Part Grouping Explanation
Substitute parts for the ABS10-G are qualified based on strict electrical and mechanical parameter matching:
Primary Substitution Criteria:
- Diode Type: Single Phase bridge rectifier
- Voltage - Peak Reverse (Max): 1 kV
- Current - Average Rectified (Io): 1 A
- Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A (or equivalent test condition)
- Operating Temperature Range: -55°C to 150°C (TJ)
- Mounting Type: Surface Mount
- Package / Case: 4-SMD, Gull Wing
- RoHS Status: ROHS3 Compliant
- Moisture Sensitivity Level (MSL): 1 (Unlimited)
Substitute parts are grouped into two categories:
Category 1: Manufacturer Recommended Substitute ABS10-HF from Comchip Technology maintains identical electrical specifications and packaging, with active product status and improved inventory availability.
Category 2: Parametric Equivalents Parts from alternative manufacturers (Diodes Incorporated, SMC Diode Solutions, Panjit International Inc., MDD, Taiwan Semiconductor Corporation, and Vishay) meet all core electrical parameters and package requirements. Minor variations in reverse leakage current (2–10 µA @ 1000 V) remain within acceptable tolerance for bridge rectifier applications. Supplier device packages may differ (ABS, 4-SOPA, 4-MDI, DBS, DBLS) while maintaining 4-SMD gull wing form factor compatibility.

Frequently Asked Questions (FAQ)
Q: Can ABS10-HF be used as a direct replacement for ABS10-G? A: Yes. ABS10-HF is the manufacturer-recommended substitute with identical electrical specifications, package type (ABS), and thermal range. The primary difference is active product status and improved availability.
Q: What is the difference between ABS supplier device package and alternative packages (4-SOPA, 4-MDI, DBS, DBLS)? A: All packages maintain the 4-SMD gull wing surface mount form factor and are mechanically compatible on standard PCB layouts. Supplier device package designations reflect manufacturer-specific naming conventions but do not affect electrical performance or footprint compatibility.
Q: Are there electrical differences between the original ABS10-G and substitute parts? A: All substitute parts meet the core specifications (1 kV, 1 A, 1.1 V forward drop). Minor variations exist in reverse leakage current: the original specifies 5 µA @ 1000 V, while some substitutes (DBLS107G, DBLS107GH) specify 2 µA @ 1000 V, and DB107S specifies 10 µA @ 1000 V. These variations remain within acceptable tolerance for bridge rectifier applications.
Q: Is DBLS107GH suitable for automotive applications? A: Yes. DBLS107GH carries AEC-Q101 automotive qualification and is suitable for automotive-grade designs. It meets all electrical specifications of the original part with lower reverse leakage performance.
Q: What is the difference between DBLS107G and DBLS107GH? A: DBLS107G is a standard industrial-grade part. DBLS107GH is the automotive-qualified variant (AEC-Q101) with identical electrical specifications. Selection depends on application requirements.
Q: Can I use parts with different supplier device packages interchangeably? A: Yes, provided the 4-SMD gull wing form factor is maintained. All listed substitute parts use this package type and are mechanically compatible on standard PCB layouts. Verify footprint compatibility with your PCB design tools.
Q: Which substitute offers the best inventory availability? A: DB107S (MDD) offers the highest stock level at 44,552 pcs, followed by DF10S-E3/77 (Vishay) at 26,100 pcs. Both are active products with strong supply chain support.
