Vishay General Semiconductor - Diodes Division SBYV26C-M3/73

Overview

SBYV26C-M3 from Vishay General Semiconductor is a glass-passivated ultrafast rectifier diode in DO-204AL (DO-41) package, rated for 600 V repetitive peak reverse voltage, 1.0 A average forward current, and 30 ns reverse recovery time. It delivers low forward voltage drop (1.3 V at 1.0 A, TJ = 175 °C), high surge capability (30 A IFSM), and operates up to 175 °C junction temperature-ideal for high-frequency freewheeling in SMPS inverters for telecom infrastructure.

For engineers reviewing the SBYV26C-M3 datasheet, SBYV26C-M3 pinout, SBYV26C-M3 application, or SBYV26C-M3 equivalent, key selection criteria include ultrafast trr performance, thermal robustness in compact through-hole packages, low leakage (<5 μA at 25 °C), and compliance with MIL-S-19500 environmental standards and JESD 201 Class 2 whisker resistance.

Technical Context

This device employs a SUPERECTIFIER® structure with cavity-free glass-passivated junction, enabling stable operation under high dv/dt and thermal stress. Its 30 ns reverse recovery time and 7.0 A/μs dIr/dt rating support efficient switching in 100–500 kHz DC-DC converters and PFC stages.

The DO-204AL package features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, halogen-free molding compound (UL 94 V-0), and M3 suffix indicating JESD 201 Class 2 whisker resistance-ensuring long-term solder joint reliability in industrial PCB assemblies.

FAQ

What is the maximum junction temperature rating for the SBYV26C-M3?

The SBYV26C-M3 has a maximum junction temperature (TJ max.) of +175 °C, verified per Vishay Document Number 89440. This rating allows continuous operation in high-ambient environments such as enclosed telecom power modules or industrial control cabinets. Derating curves in Figure 1 confirm 1.0 A IF(AV) is maintained up to 85 °C lead temperature, making SBYV26C-M3 suitable for thermally demanding applications where standard 150 °C diodes would require oversized heatsinks.

Does the SBYV26C-M3 meet RoHS and halogen-free requirements?

Yes, the SBYV26C-M3 is halogen-free, RoHS-compliant, and carries the M3 suffix denoting compliance with JESD 201 Class 2 whisker testing. Its molding compound meets UL 94 V-0 flammability rating, and all materials are categorized per Vishay's compliance documentation (www.vishay.com/doc?99912). The "Base P/N-M3" designation explicitly confirms commercial-grade environmental compliance for SBYV26C-M3.

What is the reverse recovery time (trr) specification for the SBYV26C-M3, and under what test conditions?

The SBYV26C-M3 has a maximum reverse recovery time (trr) of 30 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per Electrical Characteristics table on page 2 of Document Number 89440. This value is guaranteed across the full operating temperature range and reflects true ultrafast behavior essential for minimizing switching losses in 200–500 kHz SMPS designs.

Can the SBYV26C-M3 be used in surface-mount applications?

No, the SBYV26C-M3 uses a DO-204AL (DO-41) axial lead package designed exclusively for through-hole PCB mounting. It lacks surface-mount terminations or land patterns. For SMT equivalents, engineers should consider Vishay's SS16HE3/52T (SMA) or SB260-E3/54 (SMB), though those differ in trr, VF, and thermal performance. SBYV26C-M3 requires 0.375" (9.5 mm) lead length for rated IF(AV) derating per Figure 1.

What is the typical junction-to-ambient thermal resistance (RθJA) for the SBYV26C-M3?

The typical thermal resistance from junction to ambient (RθJA) for the SBYV26C-M3 is 70 °C/W, measured with 0.375" (9.5 mm) lead length mounted on a PCB with 0.5" × 0.5" (12 mm × 12 mm) copper pads (Note 1, Thermal Characteristics table). This value enables accurate thermal modeling in layout-dependent applications such as densely packed telecom power boards where airflow is limited.
