STPS1H100MF Equivalent & Substitute Parts

Part Overview

The STPS1H100MF is a Schottky rectifier diode manufactured by STMicroelectronics, rated for 100 V DC reverse voltage and 1 A average rectified current. This surface mount component features fast recovery characteristics with a maximum forward voltage of 770 mV at 1 A and operates with a maximum junction temperature of 175°C. The part is actively produced and maintains full RoHS3 compliance with unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance parameters are maintained across the same functional category. Alternative sources become necessary due to supply chain considerations, inventory availability, or specific application packaging requirements while preserving core electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the STPS1H100MF is determined by strict equivalence across the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Schottky diode technology classification
• 100 V maximum DC reverse voltage rating
• 1 A average rectified current capacity
• 770 mV maximum forward voltage at 1 A
• Fast recovery speed characteristic (≤ 500ns, > 200mA)
• Surface mount mounting type
• RoHS3 compliance status
• MSL 1 (Unlimited) moisture sensitivity rating

Package Variation Allowance: Substitute parts may employ different surface mount package types (DO-222AA, POWERDI®123, SOD-123W) provided all electrical parameters remain equivalent. Package selection depends on specific PCB layout requirements and thermal management considerations within the application circuit.

All identified substitutes maintain active product status and full regulatory compliance with REACH and EAR99 classifications.

Parameter Comparison

Engineering Selection Recommendations

All three diodes meet the core electrical specifications for 100 V, 1 A Schottky rectifier applications. Selection between STPS1H100MF, DFLS1100-7, and PMEG10010ELRX is determined by package compatibility with existing PCB designs and thermal layout requirements.

STPS1H100MF (STMicroelectronics, DO-222AA): Maintains the original package specification. Suitable for designs already qualified to DO-222AA footprint geometry.

DFLS1100-7 (Diodes Incorporated, POWERDI®123): Offers reduced reverse leakage current (1 µA versus 4 µA) and extended operating temperature range (-55°C to 175°C). The POWERDI®123 package provides alternative PCB layout compatibility. Inventory availability is 56,400 units.

PMEG10010ELRX (Nexperia USA Inc., SOD-123W): Delivers the lowest reverse leakage current (150 nA) and includes specified reverse recovery time (3.7 ns). The SOD-123W package accommodates space-constrained applications. Inventory availability is 53,400 units.

All parts maintain active production status, full RoHS3 compliance, and unlimited moisture sensitivity rating. Selection should be based on PCB layout constraints, thermal management requirements, and reverse leakage performance needs within the target application.

Frequently Asked Questions (FAQ)

Q: Can DFLS1100-7 or PMEG10010ELRX be used as direct replacements for STPS1H100MF?

A: Yes, both parts are electrical equivalents meeting the 100 V, 1 A Schottky diode specifications. Direct substitution requires PCB footprint compatibility with the respective package types: POWERDI®123 for DFLS1100-7 and SOD-123W for PMEG10010ELRX. The original STPS1H100MF uses DO-222AA packaging.

Q: What is the difference in reverse leakage current between these parts?

A: STPS1H100MF specifies 4 µA at 100 V. DFLS1100-7 specifies 1 µA at 100 V. PMEG10010ELRX specifies 150 nA at 100 V. Lower reverse leakage reduces standby power dissipation in applications with sustained reverse bias conditions.

Q: Are all three parts RoHS3 compliant?

A: Yes. STPS1H100MF, DFLS1100-7, and PMEG10010ELRX all carry ROHS3 Compliant status and are REACH Unaffected with EAR99 export classification.

Q: What is the operating temperature range for each part?

A: STPS1H100MF and PMEG10010ELRX specify a maximum junction temperature of 175°C. DFLS1100-7 specifies an operating range of -55°C to 175°C, providing extended low-temperature operation capability.

Q: Do these parts have different moisture sensitivity requirements?

A: No. All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Which part offers the best high-frequency performance?

A: PMEG10010ELRX includes a specified reverse recovery time of 3.7 ns, supporting applications requiring fast switching transitions. STPS1H100MF and DFLS1100-7 specify fast recovery speed classification (≤ 500ns, > 200mA) without individual reverse recovery time values.

Q: Are there inventory considerations for these substitutes?

A: STPS1H100MF has 100,200 units in stock. DFLS1100-7 has 56,400 units in stock. PMEG10010ELRX has 53,400 units in stock. All parts maintain active production status.
