Product details
Overview
ZVP4105ASTOA from Zetex Semiconductors (now Diodes Incorporated) is a P-channel enhancement-mode vertical DMOS FET rated for -50 V VDS, 10 Ω RDS(on) at VGS = -5 V, and -175 mA continuous drain current. It operates in low-power switching roles such as load switching and level translation in battery-powered instrumentation and portable logic interfaces.
For engineers reviewing the ZVP4105ASTOA datasheet, ZVP4105ASTOA pinout, ZVP4105ASTOA application, or ZVP4105ASTOA equivalent, key selection criteria include verified gate threshold range (-0.8 to -2.0 V), guaranteed RDS(on) ≤10 Ω under pulsed conditions, and TO-92-compatible leadform with confirmed Drain-Gate-Source terminal assignment.
Technical Context
This device uses vertical DMOS construction to achieve stable breakdown voltage and low on-resistance in a through-hole package. Its enhancement-mode operation requires negative gate bias relative to source to conduct, with gate threshold tightly specified between -0.8 V and -2.0 V at -1 mA drain current.
Switching performance is characterized with 50 Ω source impedance and sub-5 ns pulse rise time: turn-on delay is 10 ns, rise time 10 ns, turn-off delay 18 ns, and fall time 25 ns at VDD ≈ -30 V and ID = -270 mA - confirming suitability for medium-speed digital control paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | -50 V - maximum blocking voltage before avalanche conduction in reverse-biased drain-source path |
| RDS(on) | 10 Ω @ VGS = -5 V, ID = -100 mA - defines power loss and voltage drop in saturated switch mode |
| ID (cont) | -175 mA @ Tamb = 25°C - continuous DC current handling limited by 625 mW package power dissipation |
| VGS(th) | -0.8 to -2.0 V @ ID = -1 mA - ensures reliable turn-on with standard CMOS/TTL logic-level drive |
| Ciss | 40 pF @ VDS = -25 V, VGS = 0 V - impacts gate drive energy and high-frequency switching efficiency |
| td(off) | 18 ns - determines minimum off-time in PWM-controlled loads operating up to ~5 MHz |
Pinout & Package
Supplied in E-Line TO-92-compatible plastic package with molded leads and standardized footprint. Pin identification follows standard TO-92 orientation: viewed from flat side with leads down, left-to-right pin order is Drain–Gate–Source.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Left) | Drain | Main current-carrying terminal; connected to high-side or floating load node |
| Pin 2 (Center) | Gate | Control electrode; requires negative bias relative to source to enable conduction |
| Pin 3 (Right) | Source | Reference terminal for gate drive and current return path; tied to system ground or positive rail |
Key Features
| Feature | Design Value |
|---|---|
| P-channel enhancement mode | Enables high-side switching without level-shifting circuitry when source is tied to positive supply |
| Guaranteed RDS(on) ≤10 Ω | Ensures <175 mW conduction loss at full rated current, supporting thermally constrained PCB layouts |
| TO-92-compatible leadform | Allows direct replacement of legacy small-signal MOSFETs in existing through-hole designs |
| Low gate threshold range (-0.8 to -2.0 V) | Permits direct interface with 3.3 V or 5 V logic outputs without external gate drivers |
Applications
| Battery-Powered Load Switch | Logic-Level Signal Inversion |
|---|---|
Use Scenario: Enabling/disabling power to sensor modules in handheld medical devices during sleep cycles. IC Role / Device Role / Timing Role: High-side P-channel switch controlled by microcontroller GPIO. Use Value: Low RDS(on) minimizes voltage droop and self-heating during 100–200 mA active periods. | Use Scenario: Converting active-high logic signals to active-low outputs for legacy interface compatibility. IC Role / Device Role / Timing Role: Single-transistor inverter stage with pull-up resistor. Use Value: Verified 10 ns rise/fall times support clean signal transitions up to 10 MHz clock domains. |
| Portable Instrumentation Power Gating | Low-Voltage Level Translation |
Use Scenario: Isolating analog front-end circuitry from digital subsystems in multimeter designs. IC Role / Device Role / Timing Role: Standby-mode isolation switch between 3.3 V analog rail and digital core. Use Value: -100 nA max IDSS at 125°C prevents leakage-induced offset drift in precision measurement paths. | Use Scenario: Interfacing 1.8 V FPGA I/O to 3.3 V peripheral logic in compact IoT edge nodes. IC Role / Device Role / Timing Role: Bidirectional level shifter using gate-driven source-follower configuration. Use Value: Gate threshold range allows robust turn-on with 1.8 V logic high while maintaining noise margin against VGS(th) variation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel low-power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZVP3306A | VDS = -60 V, RDS(on) = 12 Ω @ VGS = -10 V - higher voltage rating but higher on-resistance at logic-level drive | Preferred where >50 V transient immunity required; less suitable for 3.3 V gate drive | Select if system must withstand >50 V load dump events; verify gate drive capability matches VGS(th) distribution |
| DMG2305UVT | SO-8 package, RDS(on) = 45 mΩ @ VGS = -4.5 V - lower resistance but surface-mount only and higher gate charge | Optimized for automated assembly and higher-current loads (>500 mA); incompatible with through-hole layouts | Choose for volume SMT production requiring <50 mΩ on-resistance; not a drop-in replacement for TO-92 footprints |
Compared with ZVP4105ASTOA, ZVP3306A offers higher voltage margin but reduced logic-level drivability, while DMG2305UVT delivers significantly lower RDS(on) in SMT form but eliminates manual assembly compatibility and increases gate drive demand.

FAQ
What is the maximum safe gate-source voltage for ZVP4105ASTOA?
The absolute maximum VGS is ±20 V. Exceeding this risks irreversible gate oxide damage. For reliable operation, gate drive should remain within -12 V to +5 V, with typical use at -5 V for full enhancement. Transient spikes above ±15 V require clamping diodes or RC snubbers in high-noise environments.
Can ZVP4105ASTOA be used as a high-side switch with 3.3 V logic control?
Yes - its gate threshold range of -0.8 V to -2.0 V ensures turn-on with 3.3 V logic high referenced to source. When source is at 3.3 V, applying 0 V to gate yields -3.3 V VGS, well within the conduction region. No level shifter is needed, but ensure gate drive sink capability meets 10 nA IGSS specification.
How does temperature affect RDS(on) in ZVP4105ASTOA?
RDS(on) increases with junction temperature, typically +0.5%/°C. At 125°C, it rises to approximately 13.5 Ω versus 10 Ω at 25°C. This must be factored into thermal design: at -175 mA, power dissipation climbs from 306 mW to ~340 mW, requiring adequate copper area or forced airflow in sealed enclosures.
Is ZVP4105ASTOA RoHS compliant and halogen-free?
Yes - as manufactured by Diodes Incorporated post-acquisition, ZVP4105ASTOA meets RoHS Directive 2011/65/EU and is certified halogen-free per IEC 61249-2-21. The TO-92 package uses matte tin-plated leads and epoxy molding compound compliant with JEDEC J-STD-020 moisture sensitivity level 1.
