ESH2PDHM3/84A Equivalent & Substitute Parts

Part Overview

The ESH2PDHM3/84A is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount diode operates at 200 V DC reverse voltage with a 2 A average rectified current rating and features fast recovery characteristics with a 25 ns reverse recovery time. The device is housed in a DO-220AA (SMP) package and is qualified to AEC-Q101 automotive standards. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Finding equivalent substitute parts is necessary to ensure supply chain continuity, optimize inventory management, and maintain design flexibility across manufacturing locations and procurement channels.

Substitute Part Grouping Explanation

Substitution eligibility for the ESH2PDHM3/84A is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 980 mV @ 2 A
• Reverse Recovery Time (trr): 25 ns
• Current - Reverse Leakage @ Vr: 1 µA @ 200 V
• Capacitance @ Vr, F: 25 pF @ 4V, 1MHz
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical & Package Parameters (Must Match Exactly):

• Package / Case: DO-220AA
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 175°C

Compliance & Status Parameters:

• Technology: Standard
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• Part Status: Active

Substitute parts must be from the same manufacturer series (eSMP®) and maintain identical electrical performance characteristics. Packaging format variations (Cut Tape vs. Tape & Reel) do not affect electrical equivalence but may impact procurement and logistics considerations.

Parameter Comparison

Engineering Selection Recommendations

The ESH2PD-M3/84A is a direct parametric equivalent to the ESH2PDHM3/84A. Both parts are manufactured by Vishay General Semiconductor - Diodes Division within the eSMP® series and share identical electrical, thermal, and mechanical specifications. The primary distinction between these parts is the packaging format: the ESH2PDHM3/84A is supplied in Cut Tape (CT) & Digi-Reel® format, while the ESH2PD-M3/84A is supplied in standard Tape & Reel (TR) format.

Both parts maintain active production status and full compliance with ROHS3 and REACH requirements. Both are qualified to AEC-Q101 automotive standards and feature unlimited moisture sensitivity level (MSL 1), eliminating concerns regarding shelf life and storage conditions.

Selection between these equivalent parts should be based on procurement requirements and packaging format compatibility with assembly equipment. The ESH2PD-M3/84A offers higher current inventory availability (27,300 pcs vs. 9,200 pcs), which may provide supply chain advantages for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can the ESH2PD-M3/84A be used as a direct replacement for the ESH2PDHM3/84A in existing designs?

A: Yes. The ESH2PD-M3/84A is a direct parametric equivalent. All electrical characteristics, thermal ratings, and mechanical dimensions are identical. The only difference is the packaging format (Tape & Reel vs. Cut Tape & Digi-Reel®). If your assembly equipment is compatible with standard Tape & Reel packaging, this substitution requires no design changes.

Q: What is the difference between Cut Tape (CT) & Digi-Reel® and standard Tape & Reel (TR) packaging?

A: Cut Tape & Digi-Reel® is a flexible packaging format that allows for both manual component selection and automated reel feeding. Standard Tape & Reel (TR) is optimized for high-speed automated assembly equipment. The electrical and mechanical properties of the diode itself are unchanged; the difference is purely in the delivery and handling format.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the ESH2PDHM3/84A and ESH2PD-M3/84A are qualified to AEC-Q101 automotive standards and are rated for automotive-grade reliability and performance.

Q: Do these parts have any moisture sensitivity concerns?

A: No. Both parts carry Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life under normal storage conditions. No special moisture control measures are required during storage or handling.

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

A: The reverse recovery time (trr) is 25 ns for both parts. This parameter defines how quickly the diode transitions from conducting to blocking state when the applied voltage reverses. The 25 ns specification classifies these as fast recovery diodes, suitable for high-frequency switching applications and power supply circuits where switching losses must be minimized.

Q: Can I use these diodes in circuits operating above 200 V?

A: No. The maximum DC reverse voltage rating is 200 V for both parts. Operating above this voltage will result in diode failure. If your application requires higher voltage ratings, a different diode part number with a higher Vr specification must be selected.

Q: What is the maximum forward voltage drop at rated current?

A: The maximum forward voltage drop is 980 mV at 2 A for both parts. This specification is critical for power dissipation calculations and thermal management in rectifier circuits.
