ES07B-M-08 Equivalent & Substitute Parts

Part Overview

The ES07B-M-08 is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount diode is rated for 100 V DC reverse voltage with 500 mA average rectified current and features fast recovery characteristics suitable for automotive applications. The part is currently active in production with AEC-Q101 automotive qualification and ROHS3 compliance.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the same package type and functional specifications. Alternative packaging formats may be required based on supply chain availability or manufacturing process requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the ES07B-M-08 is determined by strict equivalence across the following critical parameters:

Voltage Rating: 100 V DC reverse voltage (Vr) maximum
Current Rating: 500 mA average rectified current (Io)
Forward Voltage: 980 mV maximum at 1 A forward current
Recovery Characteristics: Fast recovery with 25 ns reverse recovery time
Reverse Leakage: 10 µA at 100 V
Package Type: DO-219AB surface mount package
Automotive Grade: AEC-Q101 qualification required
Temperature Range: -55°C to 150°C junction operating temperature

The ES07B-GS08 meets all electrical and mechanical equivalence criteria. The primary difference between these parts is the packaging format: ES07B-M-08 is supplied in Tape & Reel (TR) format, while ES07B-GS08 is supplied in Cut Tape (CT) & Digi-Reel® format. Both parts share the same base product number (ES07) and are manufactured by the same supplier.

Engineering Selection Recommendations

Both ES07B-M-08 and ES07B-GS08 are active production parts with identical electrical specifications and automotive-grade qualifications. Selection between these parts is based on packaging and supply requirements rather than electrical performance.

ES07B-M-08 (Tape & Reel format) is appropriate for high-volume automated assembly operations where continuous reel feeding is standard practice.

ES07B-GS08 (Cut Tape & Digi-Reel® format) provides flexibility for mixed-volume production environments and offers higher inventory availability (110,300 pcs vs. 1,037 pcs).

Both parts maintain ROHS3 compliance, AEC-Q101 automotive qualification, and identical electrical performance across the full operating temperature range of -55°C to 150°C. The choice between these substitutes does not affect circuit performance or reliability characteristics.

Frequently Asked Questions (FAQ)

Q: Can ES07B-GS08 be used as a direct replacement for ES07B-M-08 in circuit design?

A: Yes. Both parts are electrically identical with matching voltage ratings (100 V), current ratings (500 mA), forward voltage characteristics (980 mV @ 1 A), and recovery times (25 ns). They share the same DO-219AB package and automotive qualification (AEC-Q101).

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) format supplies components on continuous reels for automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel® format provides components in cut tape segments with optional reel packaging, offering flexibility for lower-volume or mixed-component assembly processes.

Q: Are there any temperature or environmental performance differences between these parts?

A: No. Both parts operate across the identical temperature range (-55°C to 150°C junction temperature) and maintain the same reverse leakage current (10 µA @ 100 V) and capacitance characteristics (4 pF @ 4V, 1MHz) across all operating conditions.

Q: Do both parts meet automotive compliance requirements?

A: Yes. Both ES07B-M-08 and ES07B-GS08 carry automotive grade designation and AEC-Q101 qualification. Both are ROHS3 compliant and REACH unaffected.

Q: Which part should be selected for new designs?

A: Selection depends on manufacturing process requirements. For high-volume automated assembly with reel feeding, ES07B-M-08 is standard. For flexible production environments or when higher inventory availability is required, ES07B-GS08 is appropriate. Electrical performance and reliability are identical.

Q: Can these parts be mixed in the same production batch?

A: Yes. Since both parts are electrically and mechanically equivalent with identical package specifications (DO-219AB), they can be used interchangeably within the same circuit design and production environment.
