Key Parameters

Substitute Part Grouping Explanation

Substitution of the ESH3B V7G is determined by strict equivalence across the following critical parameters:

• Voltage Rating: 100 V DC reverse voltage maximum
• Current Rating: 3 A average rectified current
• Speed Classification: Fast recovery diode with reverse recovery time of 20 ns
• Package Type: DO-214AB (SMC) surface mount package
• Reverse Leakage: 5 µA @ 100 V
• Capacitance: 45 pF @ 4V, 1MHz
• Temperature Range: -55°C to 175°C junction operating temperature
• Compliance: ROHS3 compliant, MSL 1 (Unlimited)

The substitute part ESH3B maintains identical electrical and mechanical specifications across all parameters, differing only in packaging format (Tape & Reel versus bulk) and product status (Active versus Discontinued).

Parameter Comparison

Engineering Selection Recommendations

The ESH3B substitute part is a direct functional equivalent to the ESH3B V7G. Both parts share identical electrical specifications, mechanical package dimensions, and compliance certifications. The primary distinction is product status: ESH3B V7G is discontinued, while ESH3B remains in active production with higher inventory availability (10,300 pieces versus 962 pieces).

Selection of ESH3B is appropriate for new designs, production runs, and component replenishment. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications. The MSL 1 rating indicates unlimited shelf life under standard storage conditions.

The packaging format difference (Tape & Reel for ESH3B versus bulk for ESH3B V7G) does not affect electrical or mechanical compatibility. Component procurement should prioritize the active ESH3B part number to ensure supply chain continuity and long-term availability.

Frequently Asked Questions (FAQ)

Q: Can ESH3B directly replace ESH3B V7G in existing circuit designs?

A: Yes. ESH3B provides complete functional equivalence across all electrical parameters, including voltage rating (100 V), current rating (3 A), reverse recovery time (20 ns), and operating temperature range (-55°C to 175°C). The DO-214AB package dimensions are identical, enabling direct PCB footprint compatibility.

Q: What is the difference between ESH3B V7G and ESH3B?

A: The parts are electrically and mechanically identical. ESH3B V7G is discontinued at DiGi Electronics, while ESH3B remains in active production. ESH3B is supplied in Tape & Reel packaging format, whereas ESH3B V7G was supplied in bulk packaging. Both maintain ROHS3 compliance and identical performance specifications.

Q: Are there any compliance or certification differences between these parts?

A: No. Both ESH3B V7G and ESH3B carry identical certifications: ROHS3 compliant, REACH unaffected, MSL 1 (Unlimited), and EAR99 ECCN classification. Regulatory requirements are satisfied by either part number.

Q: Does the Tape & Reel packaging of ESH3B affect component performance?

A: No. Tape & Reel packaging is a supply format only. It does not alter electrical characteristics, thermal performance, or mechanical compatibility. The component itself remains identical to bulk-packaged versions.

Q: What is the reverse recovery time specification, and why is it important?

A: Reverse recovery time (trr) is 20 nanoseconds for both parts. This parameter defines the speed at which the diode transitions from forward conduction to reverse blocking. The 20 ns specification classifies both parts as fast recovery diodes, suitable for high-frequency switching applications and power supply circuits.

Q: Can ESH3B be used in applications requiring the full -55°C to 175°C temperature range?

A: Yes. ESH3B maintains the complete operating temperature range of -55°C to 175°C junction temperature, identical to ESH3B V7G. No thermal derating is required within this range.

Q: What does MSL 1 (Unlimited) mean for storage and handling?

A: MSL 1 indicates the component has unlimited shelf life under standard storage conditions (typically 23°C ± 2°C, 45% to 75% relative humidity). No baking or special moisture control procedures are required prior to assembly.
