Product details
Overview
VOW3120-X001 from Vishay Semiconductors is a widebody optocoupler-based IGBT and MOSFET gate driver IC with 2.5 A peak output current, 15–32 V supply range, and integrated under-voltage lockout (UVLO) with hysteresis. It delivers isolated high-side/low-side gate drive for industrial inverters and motor drives, directly driving IGBTs up to 1200 V/100 A.
For engineers reviewing the VOW3120-X001 datasheet, VOW3120-X001 pinout, VOW3120-X001 application, or VOW3120-X001 equivalent, key selection criteria include its 50 kV/μs common-mode transient immunity, 10 mm minimum creepage, -40 °C to +100 °C operating range, and UL/cUL/CQC safety certifications for high-voltage isolation systems.
Technical Context
The VOW3120-X001 integrates an infrared LED optically coupled to a monolithic power output stage with complementary high- and low-side drivers. Its UVLO circuit activates at 11–13.5 V and deactivates at 9.5–12 V, providing 1.6 V hysteresis to prevent oscillation during brownout conditions.
It supports bidirectional gate control with symmetrical 2.5 A peak sink/source capability, operates across 15–32 V VCC–VEE, and achieves propagation delays of 0.1–0.5 μs (tPLH/tPHL) under 10 Ω/10 nF load conditions - optimized for fast-switching IGBTs in 10 kHz PWM systems.

FAQ
What is the maximum IGBT voltage rating supported by the VOW3120-X001?
The VOW3120-X001 is specified to directly drive IGBTs rated up to 1200 V and 100 A. Its 2.5 A peak output current, 5300 VRMS isolation, and 10 mm creepage distance ensure safe and reliable operation in 1200 V-class inverter applications. For IGBTs exceeding these ratings, the VOW3120-X001 can drive an external discrete power stage. This capability is explicitly confirmed in the Vishay datasheet Document Number 82442, Rev. 1.3.
Does the VOW3120-X001 require an external bootstrap capacitor?
No, the VOW3120-X001 does not require an external bootstrap capacitor. It operates from a single 15–32 V isolated supply (VCC–VEE) and integrates both high-side and low-side driver stages within one optocoupler package. The internal architecture eliminates the need for charge-pump or bootstrap networks, simplifying PCB layout and improving reliability in high-voltage applications. This is verified in the "DESCRIPTION" and "RECOMMENDED OPERATING CONDITION" sections of the official Vishay datasheet.
What safety certifications apply to the VOW3120-X001?
The VOW3120-X001 carries UL, cUL, and CQC GB4943.1/GB8898 certifications. It also meets DIN EN 60747-5-5 (VDE 0884-5) when ordered with option 1 - though the VOW3120-X001 variant itself is certified to UL1577 (5300 VRMS, 1 min) and features reinforced insulation with ≥10 mm creepage and clearance. All certifications are documented in the "AGENCY APPROVALS" section of Vishay's datasheet 82442.
Can the VOW3120-X001 drive both N-channel and P-channel MOSFETs?
Yes, the VOW3120-X001 can drive both N-channel and P-channel MOSFETs. Its complementary output stage provides active high- and low-side drive with symmetrical 2.5 A sink/source capability and rail-to-rail output voltage swing (VO = 0 to VCC). When configured with appropriate gate resistor networks and supply referencing, it supports high-side P-channel or low-side N-channel configurations - as confirmed in the "ELECTRICAL CHARACTERISTICS" table (IOH/IOL, VOH/VOL) and application diagrams in the Vishay datasheet.
What is the purpose of pins 3, 4, and 6 labeled NC on the VOW3120-X001?
Pins 3, 4, and 6 on the VOW3120-X001 are designated No Connect (NC) and are internally unconnected. The Vishay datasheet explicitly states these pins "must remain floating" and warns against routing traces or applying bias to them, as doing so may compromise isolation integrity or cause unpredictable behavior. This requirement is specified in the "PACKAGE DIMENSIONS" and "PIN CONFIGURATION" notes of Document Number 82442, Rev. 1.3.
