ESH1PDHM3/85A Equivalent & Substitute Parts

Part Overview

The ESH1PDHM3/85A is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, classified within the eSMP® series. This surface mount diode operates at 200 V DC reverse voltage with 1 A average rectified current and features fast recovery characteristics with a 25 ns reverse recovery time. The device is housed in a DO-220AA (SMP) package and is supplied in Tape & Reel (TR) packaging format.

The ESH1PDHM3/85A maintains Active product status and carries automotive-grade qualification (AEC-Q101), making it suitable for demanding applications requiring reliability and temperature stability across the -55°C to 175°C junction temperature range. Substitute parts are identified to address packaging format availability, inventory requirements, and equivalent electrical performance within the same product family.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ESH1PDHM3/85A are identified based on electrical and mechanical parameter equivalence within the eSMP® product family. All substitute candidates maintain identical specifications across the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 900 mV @ 1 A
• Reverse Recovery Time (trr): 25 ns
• Current - Reverse Leakage @ Vr: 1 µA @ 200 V
• Capacitance @ Vr, F: 25 pF @ 4V, 1MHz
• Operating Temperature - Junction: -55°C to 175°C

Mechanical Equivalence Criteria:

• Package / Case: DO-220AA (SMP)
• Mounting Type: Surface Mount
• Base Product Number: ESH1

Substitutes differ only in packaging format (Tape & Reel versus Cut Tape) and inventory availability. The ESH1PDHM3/84A and ESH1PD-M3/84A variants are electrically and mechanically interchangeable with the main part number, with packaging format selection determined by procurement and assembly requirements.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—ESH1PDHM3/85A, ESH1PDHM3/84A, and ESH1PD-M3/84A—are Active products manufactured by Vishay General Semiconductor - Diodes Division and maintain full compliance with ROHS3 and REACH requirements. All variants carry identical electrical specifications and operate within the same temperature range.

ESH1PDHM3/85A is supplied in Tape & Reel (TR) packaging with 983 pieces in current inventory. This variant includes automotive-grade qualification (AEC-Q101) and is suitable for high-reliability applications.

ESH1PDHM3/84A is supplied in Tape & Reel (TR) packaging with 7,026 pieces in current inventory. This variant also includes automotive-grade qualification (AEC-Q101) and provides equivalent electrical and mechanical performance.

ESH1PD-M3/84A is supplied in Cut Tape (CT) packaging with 95,400 pieces in current inventory. This variant does not carry automotive-grade qualification but maintains all electrical specifications and compliance certifications. The Cut Tape format is suitable for applications where individual component handling or lower-volume assembly processes are employed.

Selection between these parts is determined by packaging format requirements and inventory availability rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Are ESH1PDHM3/85A, ESH1PDHM3/84A, and ESH1PD-M3/84A electrically interchangeable?

A: Yes. All three part numbers maintain identical electrical specifications including voltage rating (200 V), current rating (1 A), forward voltage drop (900 mV @ 1 A), reverse recovery time (25 ns), and operating temperature range (-55°C to 175°C). They are electrically interchangeable in circuit applications.

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

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging supplies components on cut segments of carrier tape, suitable for manual handling or lower-volume assembly processes. Both formats contain the same component in the same DO-220AA package.

Q: Does ESH1PD-M3/84A lack automotive qualification?

A: ESH1PD-M3/84A does not carry AEC-Q101 automotive-grade qualification. However, it maintains all electrical specifications, RoHS3 compliance, and REACH compliance. Selection of this variant depends on application requirements for automotive qualification.

Q: Can I substitute ESH1PDHM3/85A with ESH1PD-M3/84A in an automotive application?

A: Electrical substitution is valid based on identical specifications. However, if the application requires AEC-Q101 automotive qualification, ESH1PD-M3/84A is not qualified for that requirement. ESH1PDHM3/84A maintains automotive qualification and is the appropriate substitute for automotive applications.

Q: What determines the choice between these three part numbers?

A: Selection is based on three factors: (1) packaging format requirement (Tape & Reel versus Cut Tape), (2) inventory availability, and (3) automotive qualification requirement. All three are electrically and mechanically equivalent within their respective packaging formats.

Q: Are all three parts RoHS3 compliant?

A: Yes. ESH1PDHM3/85A, ESH1PDHM3/84A, and ESH1PD-M3/84A are all ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
