Product details

Overview

ZVP4525GQTA from Diodes Incorporated is a 250V P-channel enhancement-mode MOSFET in SOT223 package, featuring 14 Ω R_DS(ON) at V_GS = −10 V, −265 mA continuous drain current at T_A = +25°C, and AEC-Q101 qualification for automotive use. It serves as a high-voltage load switch in telecom call routers and solid-state relays.

For engineers reviewing the ZVP4525GQTA datasheet, ZVP4525GQTA pinout, ZVP4525GQTA application, or ZVP4525GQTA equivalent, key selection criteria include its −250 V BVDSS rating, low gate threshold (−0.8 to −2.0 V), fast switching (t_F = 10 ns), and suitability for earth recall switches and electronic hook switch circuits.

Technical Context

This trench-structured P-channel MOSFET delivers high-voltage blocking with low conduction loss, enabled by optimized channel geometry and gate oxide design. Its −2.0 V typical V_GS(TH) ensures reliable turn-on with low-voltage logic-level drive, while C_iss = 82 pF and Q_g = 3 nC support efficient high-frequency switching.

The device integrates a body diode with V_SD = 0.97 V at −200 mA and t_RR = 80 ns, enabling bidirectional current handling in relay-replacement topologies. Thermal resistance R_θJA is 63 °C/W on a 1-inch² copper pad, supporting 2.0 W power dissipation at ambient.

Key Specifications

Parameter	Value and Actual Design Meaning
BVDSS	−250 V - supports high-side switching in 200 V telecom line interfaces without breakdown risk
RDS(ON)	14 Ω @ VGS = −10 V - enables <100 mW conduction loss at −200 mA load current
ID (continuous)	−265 mA @ TA = +25°C - sufficient for low-power telecom signaling and hook-switch control
VGS(TH)	−0.8 to −2.0 V - compatible with 3.3 V or 5 V microcontroller GPIOs without level-shifting
Qg	3 nC - allows fast turn-on/turn-off with minimal gate driver power consumption
tF	10 ns - reduces switching transition time in pulse-controlled relay emulation
RθJA	63 °C/W - permits 2.0 W operation on standard FR-4 PCB with 1-inch² copper area

Pinout & Package

Package: SOT223 (Type DN), surface-mount, 4-pin variant with exposed drain tab (Pin 2) for thermal and electrical connection. Molded green compound, RoHS-compliant, matte tin terminals.

IC Role / Device Role / Timing Role: High-voltage P-channel switch isolating ground return path under microcontroller control.

Use Value: −250 V BVDSS withstands line surges; 14 Ω RDS(ON) limits voltage drop to <300 mV at 20 mA fault current.

Use Scenario: Replacing mechanical hook switches in VoIP adapters and analog telephony interface cards (ATAs).

IC Role / Device Role / Timing Role: Solid-state replacement for SPST mechanical contacts, controlled by MCU GPIO.

Use Value: 10 ns fall time ensures <100 µs contact bounce elimination; −2.0 V VGS(TH) guarantees turn-on with 3.3 V logic.

Telecom Call Routers

Solid State Relays

Use Scenario: Routing analog voice signals between multiple lines in carrier-grade PBX systems.

IC Role / Device Role / Timing Role: Signal-path MOSFET switch in analog crosspoint matrix with isolation and low crosstalk.

Use Value: C_oss = 16 pF and Crss = 5 pF minimize signal feedthrough; 82 pF Ciss enables stable driver interface.

IC Role / Device Role / Timing Role: Bidirectional load switch leveraging integrated body diode for reverse current handling.

Use Value: V_SD = 0.97 V and t_RR = 80 ns allow clean commutation; R_θJA = 63 °C/W sustains 2 W at 70°C ambient.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ZVP3306A	Lower BVDSS (−60 V), higher ID (−500 mA), same SOT223 package	Not suitable for >100 V line applications; better for low-voltage DC load switching	Select only if system voltage remains ≤60 V and higher current capability is prioritized over voltage rating
DMG2305UVT	−20 V BVDSS, 42 mΩ RDS(ON), 4.2 A ID, SC-70 package	Designed for portable logic-level switching; incompatible with telecom line voltages	Reject for any application requiring >50 V blocking; use only in battery-powered 3.3/5 V systems

Compared with ZVP4525GQTA, ZVP3306A trades voltage headroom for current capacity, while DMG2305UVT sacrifices voltage rating entirely for ultra-low RDS(ON) in compact form-neither matches the unique −250 V/low-threshold combination required for telecom relay replacement.

FAQ

Is ZVP4525GQTA suitable for 24V automotive body electronics?

No. While AEC-Q101 qualified, ZVP4525GQTA's −250 V BVDSS and −265 mA ID are over-specified for 24V loads. Its R_DS(ON) of 14 Ω causes excessive power loss (>1 W) at typical 24V load currents above 100 mA. Use lower-R_DS(ON) alternatives like DMP2035U for such applications.

Can ZVP4525GQTA replace mechanical relays in AC line switching?

No. ZVP4525GQTA is a DC-only P-channel MOSFET with no intrinsic zero-crossing or AC voltage blocking capability. It cannot interrupt AC mains current safely. For AC solid-state relays, use opto-triacs or back-to-back MOSFETs with appropriate gate drive and snubbing.

What is the maximum safe operating junction temperature for ZVP4525GQTA?

The absolute maximum junction temperature is +150°C per the datasheet. Derating begins at +25°C ambient: with R_θJA = 63°C/W on a 1-inch² copper pad, the device reaches 150°C at ~2.0 W dissipation. Continuous operation above 125°C requires thermal monitoring and derating per Figure 7.

Does ZVP4525GQTA require a gate resistor in series with the driving GPIO?

Yes. A 10–100 Ω gate resistor is recommended to dampen ringing caused by trace inductance and MOSFET input capacitance (C_iss = 82 pF). This prevents false triggering and reduces EMI. No resistor is needed for static DC biasing, but switching applications require controlled dV/dt.
