Product details

Overview

PHP33NQ20T from Nexperia is a standard-level N-channel TrenchMOS power MOSFET in TO-220AB (SOT78) package, rated for 200 V V_DS, 32.7 A continuous drain current at T_mb = 25 °C, and 230 W total power dissipation. It serves as a main switching element in high-efficiency DC-to-DC converters, leveraging low R_DS(on) (65 mΩ typ. @ 10 V, 15 A, 25 °C) and fast switching (t_r = 35 ns, t_f = 45 ns).

For engineers reviewing the PHP33NQ20T datasheet, PHP33NQ20T pinout, PHP33NQ20T application, or PHP33NQ20T equivalent, key selection criteria include thermal resistance to mounting base (R_th(j-mb) = 0.65 K/W), gate charge (Q_G(tot) = 32.2 nC), avalanche energy rating (E_AS = 190 mJ), and safe operating area (SOA) compliance up to 65.4 A pulsed drain current.

Technical Context

This MOSFET employs TrenchMOS technology to achieve low on-resistance and high ruggedness. Its gate threshold voltage (V_GS(th)) ranges from 2–4 V at 25 °C, enabling reliable turn-on with standard 10 V gate drive while maintaining robustness against spurious conduction at elevated temperatures (V_GS(th) ≥1 V at 175 °C).

The device integrates a body diode with V_SD = 0.87–1.2 V at 25 A and reverse recovery time (t_rr) of 150 ns, supporting synchronous rectification and freewheeling in hard-switched topologies. Its SOA is defined for both continuous and pulsed operation, with R_DS(on)-limited boundary extending to 100 V at DC and 10 µs pulses.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	200 V - Maximum blocking voltage before avalanche; supports 170 V nominal bus designs with 15% margin.
R_DS(on)	65 mΩ typ. @ 10 V, 15 A, 25 °C - Enables <1 W conduction loss at 40 A, critical for high-current DC/DC stages.
Q_G(tot)	32.2 nC - Determines gate driver power requirement; compatible with common 1-A peak drivers at ≤500 kHz.
t_r/t_f	35 ns / 45 ns - Supports >1 MHz switching with minimal overlap loss in hard-switched converters.
R_th(j-mb)	0.65 K/W - Enables 150 W dissipation with ≤100 K rise above heatsink, simplifying thermal design.
E_AS	190 mJ - Withstands unclamped inductive switching events without failure under specified test conditions.
C_iss	1870 pF - Influences gate drive loop stability and Miller effect; requires careful PCB layout for high-speed use.

Pinout & Package

PHP33NQ20T uses the SOT78 (TO-220AB) plastic single-ended package with heatsink-mounted base. The mounting base (mb) is electrically connected to the drain terminal, requiring isolation when mounted to grounded heatsinks.

Pin/Terminal	Circuit Role	Design Meaning
1 (G)	Gate	Control electrode; accepts 10 V logic-level drive; Q_GS = 6.5 nC enables fast turn-on with low gate loss.
2 (D)	Drain	Main high-side current path; internally bonded to mounting base-requires insulating washer if heatsink is grounded.
3 (S)	Source	Reference node for gate drive and current sensing; low-inductance connection essential for stable switching.

Key Features

Feature	Design Value
Low thermal resistance to mounting base	R_th(j-mb) = 0.65 K/W reduces heatsink size and cost in space-constrained power supplies.
Fast switching with low gate charge	Q_G(tot) = 32.2 nC and t_r/t_f ≤45 ns enable high-frequency operation with minimized switching loss.
TrenchMOS-enhanced ruggedness	190 mJ non-repetitive avalanche energy allows reliable operation during transient overloads and inductive kickback.
Body diode with controlled recovery	t_rr = 150 ns and Q_r = 645 nC support efficient freewheeling in buck and half-bridge topologies.
Wide temperature operation	Rated for T_j = −55 to +175 °C and V_GS(th) shift ≤3 V across range-ensures stable gate control in industrial environments.

Applications

DC-DC Buck Converter

Industrial Motor Drive Half-Bridge

Use Scenario: Primary switch in 48 V input, 12 V output synchronous buck converter delivering up to 40 A.

IC Role / Device Role / Timing Role: High-side power switch operating at 300–500 kHz with gate-driven synchronous rectification.

Use Value: 65 mΩ R_DS(on) limits conduction loss to <1.05 W at 40 A, while 35 ns rise time minimizes transition loss at 500 kHz.

Use Scenario: Upper-leg switch in 24–48 V industrial BLDC motor drive inverter stage.

IC Role / Device Role / Timing Role: Hard-switched high-side FET in three-phase bridge, commutated at ≤20 kHz.

Use Value: 200 V rating provides 2× bus voltage margin; 190 mJ E_AS withstands inductive flyback during fault conditions.

Telecom AC-DC Front-End

Server VRM High-Current Phase

Use Scenario: Active clamp switch in telecom rectifier PFC stage handling 3 kW output.

IC Role / Device Role / Timing Role: Clamping switch synchronized to main boost FET, operating at 100–200 kHz.

Use Value: Low C_oss (230 pF) and Cr_ss (70 pF) reduce capacitive losses and improve ZVS behavior in resonant clamping.

Use Scenario: Single-phase power stage in 12 V → 0.8 V server VRM delivering 120 A per phase.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP33NF20	Same V_DS (200 V), higher R_DS(on) (75 mΩ typ.), higher Q_G (45 nC), TO-220FP package with insulated tab.	Lower switching speed and higher conduction loss; better suited for lower-frequency (<100 kHz), thermally constrained layouts.	Select when electrical isolation from heatsink is required and gate drive capability exceeds 1.5 A peak.
IRF3205	Lower V_DS (55 V), much lower R_DS(on) (8.0 mΩ), higher ID (110 A), TO-220AB package.	Not suitable for 200 V systems; only applicable in ≤48 V DC/DC or motor drives where voltage stress is low.	Choose only for low-voltage, ultra-high-current applications where 200 V rating is unnecessary and R_DS(on) dominates loss budget.

Compared with STP33NF20 and IRF3205, PHP33NQ20T delivers optimal balance of 200 V rating, 65 mΩ conduction resistance, and 32.2 nC gate charge-making it uniquely suited for mid-voltage, medium-frequency industrial and telecom power conversion where both voltage margin and switching efficiency matter.

FAQ

Is PHP33NQ20T a logic-level MOSFET?

No-it is a standard-level MOSFET requiring ≥10 V gate drive for full enhancement. Its V_GS(th) is 2–4 V at 25 °C, but R_DS(on) is specified only at V_GS = 10 V. Driving below 8 V results in significantly higher on-resistance and thermal stress.

Can PHP33NQ20T be used in synchronous rectification?

Yes-the integrated body diode has t_rr = 150 ns and Q_r = 645 nC, making it suitable for synchronous rectification in buck converters up to ~300 kHz. However, external Schottky or MOSFET-based synchronous rectifiers yield lower loss in high-frequency, high-current designs.

What is the maximum continuous drain current at 100 °C mounting base temperature?

Per Figure 1 in the datasheet, the normalized I_D derating factor at T_mb = 100 °C is ~70%. Since I_D = 32.7 A at 25 °C, the maximum continuous drain current at 100 °C is approximately 23.1 A-matching the limiting value table entry for T_mb = 100 °C.

Does the mounting base require electrical isolation from the heatsink?

Yes-the mounting base (mb) is internally connected to the drain (Pin 2). If the heatsink is grounded or at a different potential than the drain circuit, an electrically isolating pad (e.g., mica or polymer film) must be used to prevent short circuits and ensure safe operation.
