Diodes Incorporated ZVNL110GTC

Overview

ZVNL110G from Diodes Incorporated is a 100V N-channel enhancement-mode MOSFET in SOT223 (Type DN) package, rated for 0.6A continuous drain current at 25°C, with R_DS(on) = 3.0Ω @ V_GS = 10V and 4.5Ω @ V_GS = 5.0V. It serves as a low-power switching device in DC-DC converters and power management circuits where space-constrained board layout and moderate voltage blocking are required.

For engineers reviewing the ZVNL110G datasheet, ZVNL110G pinout, ZVNL110G application, or ZVNL110G equivalent, key selection considerations include its 100V V_DSS, low gate charge (C_iss = 47pF typ), fast switching (t_r = 3–12ns), thermal resistance (R_θJA = 113°C/W on FR-4), and RoHS-compliant "Green" construction.

Technical Context

This MOSFET employs planar silicon process technology optimized for low R_DS(on) while maintaining controlled gate charge and body diode recovery characteristics. Its threshold voltage range (0.75–1.5V) enables reliable turn-on with standard 5V logic-level drive, and its 100V breakdown rating supports operation in 48V industrial bus and auxiliary supply rails.

The device features low input capacitance (C_iss = 47pF typ) and fast switching times (t_D(on) = 2–7ns, t_F = 2–13ns), enabling efficient operation in high-frequency PWM topologies up to ~500kHz. Its integrated body diode exhibits forward voltage of ~1.2V at 0.6A and 25°C, suitable for non-synchronous buck or flyback freewheeling paths.

FAQ

What is the maximum continuous drain current for ZVNL110G at 70°C ambient?

The datasheet specifies 0.5A continuous drain current at T_A = +70°C with proper PCB thermal relief (2oz copper, minimum pad layout). This reflects thermal derating due to increased R_θJA at elevated ambient temperature, not device degradation. Operation above this current requires active cooling or reduced duty cycle to maintain junction temperature below 150°C.

Can ZVNL110G be driven directly by a 3.3V microcontroller GPIO?

Yes - its gate threshold voltage (V_GS(th)) ranges from 0.75V to 1.5V, and R_DS(on) is specified at 4.5Ω with V_GS = 5.0V. At 3.3V, the device remains fully enhanced for ≤0.3A loads (per Figure 3), making it suitable for light-load switching such as LED control or low-current enable functions without external level shifting.

Is ZVNL110G qualified for automotive applications?

ZVNL110G is not AEC-Q101 qualified per official Diodes documentation; however, the datasheet notes that automotive-grade versions (with PPAP capability and IATF 16949 manufacturing) are available upon request. Standard ZVNL110G is intended for industrial and commercial use, and its -55°C to +150°C operating range supports extended temperature environments outside formal automotive qualification.

What is the recommended PCB pad layout for optimal thermal performance?

Diodes specifies a 1-inch square copper plate on FR-4 with 2oz copper for R_θJA = 61°C/W. The SOT223 (Type DN) exposed drain tab (Pin 2 & Pin 4) must be fully soldered to this copper area using ≥4 thermal vias (0.3mm diameter, spaced ≤2mm apart) connecting to inner or backside ground planes. Minimum pad dimensions match the package outline: 6.5mm × 7.0mm with 3.5mm center pad width (E1).
