Product details

Overview

ZVP2106ASTOB from Zetex Semiconductors (now Diodes Incorporated) is a P-channel enhancement-mode vertical DMOS FET in TO-92 package, rated for -60 V V_DS, 5 Ω R_DS(on) at V_GS = -10 V and I_D = -500 mA, with 700 mW power dissipation and -55 °C to +150 °C operating temperature range - used in low-power DC-DC converter load switches and battery protection circuits.

For engineers reviewing the ZVP2106ASTOB datasheet, ZVP2106ASTOB pinout, ZVP2106ASTOB application, or ZVP2106ASTOB equivalent, key selection criteria include verified gate threshold voltage (-1.5 V to -3.5 V), pulsed drain current capability (-4 A), normalized R_DS(on) vs. temperature behavior, and TO-92-compatible lead form factor for through-hole prototyping and space-constrained industrial controls.

Technical Context

This device operates as a normally-off P-channel MOSFET requiring negative gate drive relative to source. Its vertical DMOS structure enables stable R_DS(on) over temperature and low gate charge (Q_g ≈ 2.5 nC inferred from Crss/Ciss trends), supporting efficient switching at frequencies up to several hundred kHz.

Electrical characterization confirms tight V_GS(th) distribution (-1.5 V to -3.5 V), low IDSS leakage (< -100 µA at -48 V, 125 °C), and predictable transconductance (g_fs = 150 mS at -18 V V_DS, -500 mA I_D), making it suitable for precision current regulation in analog power rails.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	-60 V - maximum blocking voltage before avalanche onset; defines safe operation in 48 V rail protection
R_DS(on)	5 Ω @ V_GS = -10 V, I_D = -500 mA - determines conduction loss in linear or saturated switching mode
I_D (continuous)	-280 mA @ T_amb = 25 °C - sets steady-state current limit without heatsinking
P_tot	700 mW @ T_amb = 25 °C - thermal envelope for PCB-mounted TO-92 operation
V_GS(th)	-1.5 V to -3.5 V @ I_D = -1 mA - defines minimum gate drive needed for turn-on in logic-level control
g_fs	150 mS @ V_DS = -18 V, I_D = -500 mA - indicates gain for analog current-source applications
C_iss	100 pF @ V_DS = -18 V, V_GS = 0 V - impacts gate drive energy and high-frequency switching loss

Pinout & Package

Package: TO-92 (E-Line compatible), through-hole, 3-pin plastic case with standard D-G-S terminal assignment (viewed from flat side, leads down).

Pin/Terminal	Circuit Role	Design Meaning
Drain (D)	High-side current return path	Connected to negative supply or load return; handles full switched current and blocking voltage
Gate (G)	Control electrode	Receives negative voltage relative to source to modulate channel conductivity; high-impedance input
Source (S)	Reference node / current origin	Bias reference for gate drive; tied to positive rail in high-side switch configuration

Key Features

Feature	Design Value
P-channel enhancement mode	Ensures fail-safe off-state with zero gate bias; eliminates need for level-shifting in high-side switch topologies
Vertical DMOS construction	Delivers stable R_DS(on) across -55 °C to +150 °C junction range, critical for automotive under-hood use
Low gate leakage (I_GSS ≤ 20 nA)	Enables long-duration static gate biasing without drift - suitable for battery-backed enable circuits
Fast switching (t_d(on) = 7 ns, t_f = 15 ns)	Supports >200 kHz PWM operation with minimal dead-time penalty in synchronous buck controllers
TO-92 mechanical compatibility	Allows drop-in replacement of legacy ZVP2106A and ZVP2106FT variants on existing through-hole PCBs

Applications

Load Switch for 24 V Industrial Sensors

Battery Reverse-Polarity Protection

Use Scenario: Isolating 24 V sensor supply during system standby to reduce quiescent current.

IC Role / Device Role / Timing Role: High-side P-channel switch controlled by microcontroller GPIO.

Use Value: 5 Ω R_DS(on) limits voltage drop to <130 mV at 25 mA load, preserving sensor accuracy and enabling fast turn-off (t_f = 15 ns).

Use Scenario: Preventing damage when Li-ion battery pack is inserted backward into portable medical device.

IC Role / Device Role / Timing Role: Series-connected P-MOSFET in battery feed path, gate driven by battery voltage.

Use Value: -60 V V_DS rating exceeds 48 V max pack voltage; -100 µA IDSS at 125 °C ensures minimal leakage during storage.

Low-Power DC-DC Converter Synchronous Rectifier

Microcontroller-Controlled LED Dimming Driver

Use Scenario: Replacing Schottky diode in 5 V → 3.3 V buck converter to improve efficiency at light loads.

IC Role / Device Role / Timing Role: Low-side synchronous rectifier driven by controller's complementary output.

Use Value: 150 mS g_fs supports precise current mirroring; C_iss = 100 pF minimizes gate drive power at 500 kHz switching.

Use Scenario: PWM-controlled current sink for 20 mA indicator LEDs in HVAC control panel.

IC Role / Device Role / Timing Role: Linear-mode current regulator with gate biased via DAC output.

Use Value: Tight V_GS(th) tolerance (-1.5 V to -3.5 V) enables consistent LED brightness across production units without calibration.

Equivalent & Alternatives

The following parts are listed as comparable options for similar P-channel MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ZVP2106FTOB	Same die, SOT-23 package; higher thermal resistance (R_θJA = 270 °C/W vs. TO-92's 200 °C/W)	Preferred for surface-mount volume production; unsuitable for >150 mW continuous dissipation	Select for automated assembly where board space is constrained and power <150 mW
DMG2305UVT	Lower R_DS(on) (45 mΩ), but only -20 V V_DS; SOT-23, 2.2 A I_D	Not viable for 48 V systems; suited for 5–12 V logic-level loads only	Choose only if operating voltage ≤12 V and sub-100 mΩ on-resistance is required

Compared with ZVP2106FTOB and DMG2305UVT, ZVP2106ASTOB uniquely balances -60 V ruggedness, TO-92 serviceability, and 5 Ω R_DS(on) for cost-sensitive, medium-voltage industrial controls where manual rework or thermal margin matters more than footprint.

FAQ

Is ZVP2106ASTOB suitable for high-side switching with 3.3 V microcontroller GPIO drive?

No - its gate threshold voltage ranges from -1.5 V to -3.5 V, requiring a negative gate-source potential to turn on. A 3.3 V GPIO cannot directly drive it in high-side configuration without an external level shifter or charge pump to generate -5 V to -10 V gate bias relative to source.

What is the maximum continuous drain current at 85 °C ambient temperature?

Derating from 280 mA at 25 °C using the 700 mW P_tot rating and thermal resistance of ~200 °C/W for TO-92 yields approximately 180 mA at 85 °C ambient, assuming no PCB copper heatsinking. Actual value depends on board layout and airflow.

Does ZVP2106ASTOB have built-in ESD protection?

No - the datasheet does not specify human-body model (HBM) or charged-device model (CDM) ESD ratings. External TVS or series resistors are recommended for gate protection in handling or connector-exposed applications.

Can ZVP2106ASTOB replace ZVP2106A in existing designs?

Yes - ZVP2106ASTOB is a direct revision of ZVP2106A with identical electrical specifications, TO-92 pinout, and thermal performance. The "STOB" suffix denotes tape-and-reel packaging per EIA-481, but the device itself is functionally and mechanically interchangeable.
