Gate Drive Transformer SMB

Optimized Product Detail Page: Gate Drive Transformer SMB

Introduction
Gate Drive Transformers in SMB (Surface-Mount Box) packages provide critical signal isolation in high-voltage switching applications. Engineered for high isolation voltage (up to 5kVrms) and ultra-compact footprints, these Transformers enable precise MOSFET/IGBT control while minimizing propagation delay (<10ns). With reinforced insulation and ultra-low interwinding capacitance (<5pF), our SMB gate drive transformer solutions prevent shoot-through in half-bridge circuits and support switching frequencies beyond 1MHz – ideal for SiC/GaN power modules.

Key Specifications

• Isolation: 3750Vrms to 5000Vrms (60s, reinforced per IEC 60664)

• Frequency Response: 10kHz-1MHz (rise time <10ns)

• dv/dt Immunity: >50kV/μs (eliminates parasitic turn-on)

• Temperature: -40°C to +150°C (AEC-Q200 option)

• Package: SMB SMD (7.2×6.5mm) with 8mm creepage

• Turns Ratio: 1:1, 1:1.5 (±2% tolerance)Applications

Integrate these High Frequency Transformers with Power Inductors and RF Microwave Components in:

• Motor Drives: EV traction inverters, servo controllers

• Switched-Mode Power Supplies: LLC converters, UPS systems

• Renewable Energy: Solar microinverters, BMS circuits

• Industrial Systems: Welding equipment, isolated Sensor interfaces

• RF Power Stages: GaN RF amplifiers requiring gate isolation

Design Advantages

1. Noise-Immune Circuit Integration
   Triple-shielded windings eliminate common-mode interference in your gate drive transformer circuit. Compatible with EMC Filter - EMI/RFI modules for full-system compliance.

2. High-Speed Stability
   Low leakage inductance (<3μH) prevents ringing at MHz frequencies. Optimized for co-design with RF Inductor snubber networks and High Frequency Transformers.

3. Thermal Management
   High-curie-temperature cores maintain permeability at 150°C – essential when adjacent to Power Inductors in dense layouts.

4. Drop-in SMB Replacement
   Industry-standard footprints replace bulky through-hole designs. Simplifies gate drive transformer circuit prototyping and reduces PCB area by 60%.
