Product details

Overview

N0300N-T1B-AT from Renesas Electronics is an N-channel MOSFET designed for low-voltage switching applications, featuring 4.5 V gate drive capability, R_DS(on) ≤ 83 mΩ at V_GS = 4.5 V and I_D = 2.0 A, ±30 V V_DSS, and SC-96 surface-mount package - widely used in portable device power switches.

For engineers reviewing the N0300N-T1B-AT datasheet, N0300N-T1B-AT pinout, N0300N-T1B-AT application, or N0300N-T1B-AT equivalent, key selection criteria include verified 4.5 V logic-level drivability, pulsed drain current rating of ±18 A, built-in gate protection diode, thermal derating on FR-4 PCB, and Pb-free SC-96 footprint compatibility.

Technical Context

This MOSFET operates as a single N-channel enhancement-mode switch with gate threshold voltage (V_GS(off)) between 1.0 V and 2.5 V, enabling reliable turn-on from standard 4.5 V supply rails. Its forward transfer admittance |y_fs| ≥ 1.0 S at V_DS = 10 V and I_D = 2.0 A confirms strong transconductance for fast switching control.

Switching performance is characterized by t_d(on) = 6.5 ns, t_r = 3.0 ns, t_d(off) = 16.5 ns, and t_f = 3.0 ns under V_DD = 15 V, I_D = 2.0 A, and R_G = 6 Ω conditions; total gate charge Q_G = 7.4 nC supports efficient gate driver sizing.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	30 V - maximum blocking voltage before avalanche; suitable for 24 V rail switching with margin
R_DS(on) @ 4.5 V	83 mΩ max - enables <170 mW conduction loss at 2 A DC, critical for battery-powered efficiency
I_D(DC)	±4.5 A - continuous current rating with thermal limits defined for FR-4 board mounting
Q_G	7.4 nC - determines gate driver current requirement and switching transition time
C_iss	350 pF - input capacitance affecting high-frequency gate drive impedance and Miller effect
V_GS(off)	1.0–2.5 V - ensures full enhancement-mode operation with robust noise immunity at logic-level gates
V_F(S-D)	0.9 V - body diode forward voltage impacts reverse recovery and synchronous rectification losses

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
AO3400A	R_DS(on) = 44 mΩ @ V_GS = 10 V; 50 mΩ @ 4.5 V; higher C_iss (640 pF); same SC-70 package	Slightly lower R_DS(on) at 4.5 V but larger input capacitance increases gate drive demand	Prefer AO3400A only if lower conduction loss outweighs increased switching loss and gate driver burden
DMN2004LK-7	R_DS(on) = 48 mΩ @ 4.5 V; higher V_DSS (20 V); SOT-23 package; no integrated gate protection diode	Limited to ≤20 V systems; requires external ESD protection; smaller footprint but lower voltage margin	Select DMN2004LK-7 only for space-critical 12–20 V designs where gate protection is implemented externally

Compared with AO3400A and DMN2004LK-7, the N0300N-T1B-AT offers balanced trade-offs: moderate R_DS(on) at 4.5 V, integrated gate protection, 30 V rating for 24 V system margin, and SC-96 thermal performance optimized for FR-4 boards - making it especially suitable for cost-sensitive, medium-current portable power switches.

FAQ

What is the maximum continuous drain current rating for N0300N-T1B-AT?

The N0300N-T1B-AT has a DC drain current rating of ±4.5 A under specified thermal conditions - specifically when mounted on a 50 mm × 50 mm × 1.6 mm FR-4 PCB with t ≤ 5 sec. This rating assumes proper board-level heat spreading and ambient temperature ≤ 25°C; derating applies above 25°C per the published thermal curve in the datasheet.

Does N0300N-T1B-AT include built-in ESD protection?

Yes, the N0300N-T1B-AT integrates a gate-to-source protection diode explicitly described in the datasheet's Equivalent Circuit diagram and Remark section. This diode provides basic ESD immunity, but Renesas specifies that an external protection circuit remains necessary if voltages exceeding the ±20 V gate-source rating may occur in the target application.

What is the gate threshold voltage range for N0300N-T1B-AT?

The gate-to-source cut-off voltage (V_GS(off)) for N0300N-T1B-AT is specified as 1.0 V minimum to 2.5 V maximum at V_DS = 10 V and I_D = 1.0 mA. This confirmed range ensures reliable enhancement-mode behavior and compatibility with 3.3 V and 4.5 V logic families without requiring overdrive.

Can N0300N-T1B-AT be used in a high-side switching configuration?

The N0300N-T1B-AT is an N-channel MOSFET and is not inherently suited for high-side switching without a gate-boost circuit. Its gate drive requires V_GS > V_GS(th) relative to source potential; in high-side use, a charge pump or floating supply would be needed to maintain sufficient V_GS - unlike P-channel alternatives which simplify high-side implementation.

What is the thermal resistance characteristic of N0300N-T1B-AT on a standard PCB?

When mounted on a 50 mm × 50 mm × 1.6 mm FR-4 board, the N0300N-T1B-AT achieves a total power dissipation of 1.25 W (PT2), corresponding to a steady-state thermal resistance from channel to ambient of approximately 120°C/W. Transient thermal resistance data shows r_th(ch-A) drops to ~40°C/W for 10 ms pulses, supporting short-duration peak current handling.
