SE12DBHM3/I Equivalent & Substitute Parts

Part Overview

The SE12DBHM3/I is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, classified within the eSMP® series. This surface mount diode is rated for 100 V DC reverse voltage with an average rectified current of 3.2 A and operates across a junction temperature range of -55°C to 175°C. The device is qualified to AEC-Q101 automotive standards and maintains Active product status. Substitute parts are identified when electrical specifications, mechanical packaging, and compliance certifications remain equivalent across different packaging formats or supplier configurations.

Substitute Part Grouping Explanation

Substitute parts for the SE12DBHM3/I are identified based on strict equivalence of electrical and mechanical parameters. The substitution logic is based on the following criteria:

Electrical Equivalence:

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 3.2 A
• Voltage - Forward (Vf) (Max) @ If: 1.15 V @ 12 A
• Reverse Recovery Time (trr): 3 µs
• Current - Reverse Leakage @ Vr: 20 µA @ 100 V
• Capacitance @ Vr, F: 90 pF @ 4V, 1MHz
• Operating Temperature - Junction: -55°C to 175°C

Mechanical Equivalence:

• Package / Case: TO-263-3, D2PAK (2 Leads + Tab)
• Mounting Type: Surface Mount
• Supplier Device Package: TO-263AC (SMPD)

Compliance Equivalence:

• Series: eSMP®
• Technology: Standard
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected
• AEC-Q101 Qualification: Yes

Substitute parts differ only in packaging format (Tape & Reel versus Cut Tape) and inventory availability, with no variation in electrical performance or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The SE12DB-M3/I serves as a direct parametric equivalent to the SE12DBHM3/I. Both parts maintain identical electrical specifications, mechanical dimensions, and compliance certifications. The distinction between these parts is limited to packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is supplied in Cut Tape (CT) configuration.

Both parts carry Active product status and maintain AEC-Q101 automotive qualification. ROHS3 compliance and REACH unaffected status are consistent across both variants. The Moisture Sensitivity Level (MSL) rating of 1 (Unlimited) applies to both parts, indicating no moisture sensitivity constraints during storage or handling.

Selection between these parts depends on procurement requirements and assembly process specifications. Tape & Reel packaging is typically used for high-volume automated assembly operations, while Cut Tape packaging is suitable for lower-volume applications or manual assembly processes. Electrical and thermal performance characteristics remain unchanged between packaging formats.

Frequently Asked Questions (FAQ)

Q: Can SE12DB-M3/I be used as a direct replacement for SE12DBHM3/I in existing designs?

A: Yes. The SE12DB-M3/I is electrically and mechanically equivalent to the SE12DBHM3/I. All electrical parameters, including voltage ratings, current ratings, forward voltage drop, reverse recovery time, and leakage current are identical. The TO-263AC (SMPD) package footprint and pin configuration are unchanged. The only difference is the packaging format (Cut Tape versus Tape & Reel).

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on a continuous reel of carrier tape, optimized for high-speed automated pick-and-place assembly. Cut Tape (CT) packaging supplies the same components on individual tape segments, typically used for lower-volume production or manual assembly processes. The component itself and its electrical performance are identical.

Q: Are both parts qualified for automotive applications?

A: Yes. Both SE12DBHM3/I and SE12DB-M3/I carry AEC-Q101 qualification, confirming suitability for automotive-grade applications. Both parts maintain the same operating temperature range of -55°C to 175°C junction temperature.

Q: Do these parts have any moisture sensitivity concerns?

A: No. Both parts are rated at Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity constraints. Standard storage and handling practices are sufficient.

Q: Are both parts RoHS compliant?

A: Yes. Both SE12DBHM3/I and SE12DB-M3/I are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements.

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

A: The reverse recovery time (trr) for both parts is 3 µs. This parameter defines the time required for the diode to transition from forward conduction to reverse blocking when the applied voltage reverses. This specification is critical in switching applications and power conversion circuits.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, provided the assembly process accommodates the packaging format. If the design uses automated pick-and-place equipment configured for Tape & Reel format, the Cut Tape variant requires process adjustment. Conversely, if manual assembly or lower-volume processes use Cut Tape, the Tape & Reel variant requires reel-to-tape conversion. The PCB footprint and soldering requirements remain identical.
