Category 1: Direct Parametric Equivalents (Identical Electrical Specifications)

Parts S4PDHM3_B/I, S4PD-M3/86A, and S4PD-M3/87A maintain identical electrical characteristics to the main part:

Voltage - DC Reverse (Vr) (Max): 200 V
Current - Average Rectified (Io): 4 A
Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 4 A
Reverse Recovery Time (trr): 2.5 µs
Current - Reverse Leakage @ Vr: 10 µA @ 200 V
Capacitance @ Vr, F: 30 pF @ 4V, 1MHz
Package / Case: TO-277, 3-PowerDFN
Operating Temperature - Junction: -55°C to 150°C

These parts differ only in product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. standard packaging).

Category 2: Higher Current Rating Substitute (Parametric Variant)

Part TPMR10D from Taiwan Semiconductor Corporation provides a higher current rating (10 A vs. 4 A) while maintaining the same 200 V reverse voltage rating and TO-277A package. This part exhibits different electrical characteristics including faster recovery time (35 ns vs. 2.5 µs) and lower reverse leakage current (5 µA vs. 10 µA). TPMR10D is classified as Discontinued at DiGi Electronics.

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance):

S4PDHM3_B/I is the manufacturer-recommended substitute, offering identical electrical specifications with Active product status. This part maintains full compatibility with designs specified for the S4PDHM3_A/I, including automotive-grade qualification (AEC-Q101) and operating temperature range (-55°C to 150°C). S4PDHM3_B/I is available in Tape & Reel packaging format with 995 units in stock.

S4PD-M3/86A and S4PD-M3/87A are parametric equivalents with identical electrical characteristics and Active product status. S4PD-M3/86A offers the highest inventory availability (5600 units). Both parts are ROHS3 compliant and maintain the same package configuration. These parts are suitable for applications requiring the same 4 A current rating and 200 V reverse voltage specification.

For Higher Current Applications:

TPMR10D from Taiwan Semiconductor Corporation provides a 10 A average rectified current rating while maintaining the 200 V reverse voltage specification and TO-277A package footprint. This part exhibits superior recovery characteristics (35 ns vs. 2.5 µs) and lower reverse leakage current (5 µA vs. 10 µA). TPMR10D is classified as Discontinued at DiGi Electronics and should be selected only when higher current capacity is required and design modifications to accommodate different electrical characteristics are acceptable.
