Diodes Incorporated ZVP2110ASTOB

Overview

ZVP2110ASTOB from Zetex Semiconductors (now Diodes Incorporated) is a P-channel enhancement-mode vertical DMOS FET in TO-92 package, rated for -100 V V_DS, 8 Ω R_DS(on) at V_GS = -10 V, and -750 mA continuous on-state drain current. It operates across -55 °C to +150 °C and is used in low-power DC-DC converter load switches and battery protection circuits where high-voltage blocking and moderate current handling are required.

For engineers reviewing the ZVP2110ASTOB datasheet, ZVP2110ASTOB pinout, ZVP2110ASTOB application, or ZVP2110ASTOB equivalent, key selection criteria include verified -100 V breakdown voltage, gate threshold range of -1.5 V to -3.5 V, pulsed current capability up to -3 A, thermal stability over extended temperature range, and TO-92 mechanical compatibility with legacy through-hole designs.

Technical Context

This discrete MOSFET uses vertical DMOS construction to achieve high voltage blocking with low on-resistance in a small through-hole package. Its enhancement-mode operation requires negative gate bias relative to source to conduct, and its -1.5 V to -3.5 V V_GS(th) enables direct interface with standard logic-level control signals when referenced to a positive rail.

Switching performance is characterized by 7 ns turn-on delay, 15 ns rise time, 12 ns turn-off delay, and 15 ns fall time under -25 V V_DD and -375 mA load conditions. Input capacitance (C_iss = 100 pF) and reverse transfer capacitance (C_rss = 10 pF) support predictable gate drive design in low-frequency switching applications.

FAQ

Is ZVP2110ASTOB suitable for use as a high-side switch with 3.3 V logic control?

Yes. With a gate threshold voltage range of -1.5 V to -3.5 V, ZVP2110ASTOB turns on fully when driven by a 3.3 V microcontroller output pulled low (i.e., V_GS ≈ -3.3 V), delivering -750 mA at V_DS = -25 V. No level-shifting circuitry is required in this configuration.

What is the maximum safe operating temperature for continuous operation?

The device supports continuous operation up to +150 °C junction temperature. At ambient temperatures above 60 °C, derating is required: P_tot decreases linearly at 5.6 mW/°C above 25 °C, reaching zero at 150 °C. PCB copper area and airflow must be validated per application thermal profile.

Can ZVP2110ASTOB replace ZVP2100A in existing designs?

Yes. ZVP2110ASTOB is a direct functional and mechanical replacement for ZVP2100A, sharing identical TO-92 package, pinout, and electrical specifications including -100 V V_DS, 8 Ω R_DS(on), and -230 mA I_D. The "A" suffix denotes improved process consistency and tighter V_GS(th) distribution.

Does ZVP2110ASTOB require a gate resistor for switching applications?

A gate resistor is recommended to dampen ringing and limit peak gate current. For 10–100 kHz switching with 50 Ω source impedance (per datasheet test condition), a 10–47 Ω series resistor provides optimal trade-off between switching speed (7–15 ns delays/times) and EMI suppression without compromising drive strength.
