Product details

Overview

RD100P-T1-AZ from Renesas Electronics is a P-channel enhancement-mode MOSFET designed for high-side load switching in automotive and industrial power management systems, with V_DSS = −100 V, R_DS(on) = 0.14 Ω (max) at V_GS = −10 V, and continuous drain current I_D = 10 A. It operates within −55 °C to +175 °C junction temperature range and meets AEC-Q101 reliability requirements.

For engineers reviewing the RD100P-T1-AZ datasheet, RD100P-T1-AZ pinout, RD100P-T1-AZ application, or RD100P-T1-AZ equivalent, key selection criteria include its negative gate threshold voltage (V_GS(th) = −2.0 to −4.0 V), low gate charge (Q_g = 38 nC), and TO-252 (DPAK) surface-mount package optimized for thermal performance in 12 V/24 V DC systems.

Technical Context

This MOSFET employs a trench-gate structure to achieve low on-resistance and fast switching characteristics. Its body diode exhibits reverse recovery time t_rr = 120 ns and peak reverse recovery current I_RRM = 8 A, supporting efficient flyback energy handling in inductive load control.

The device features avalanche-rated ruggedness (E_AS = 120 mJ at T_J = 25 °C), enabling robust operation under transient overvoltage conditions without external snubbers in motor driver and solenoid interface circuits.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	−100 V: Maximum drain-to-source blocking voltage for use in 24 V automotive battery systems with load dump protection.
R_DS(on) max	0.14 Ω @ V_GS = −10 V: Enables <1.4 W conduction loss at 10 A, reducing heatsink requirements in space-constrained modules.
I_D (continuous)	10 A @ T_C = 25 °C: Supports medium-power loads such as fuel pumps, HVAC actuators, and ECU power rails.
V_GS(th)	−2.0 to −4.0 V: Ensures reliable turn-on with standard microcontroller GPIOs or dedicated gate drivers operating at −5 V or −8 V.
Q_g	38 nC: Reduces switching losses and driver power demand in PWM-controlled applications up to 100 kHz.
E_AS	120 mJ: Withstands single-pulse inductive energy without failure, eliminating need for external clamping in relay replacement designs.

Pinout & Package

RD100P-T1-AZ is housed in a TO-252 (DPAK) plastic surface-mount package with exposed drain pad for enhanced thermal dissipation. The package measures 6.5 mm × 6.1 mm × 2.3 mm and supports solder reflow per J-STD-020.

Pin/Terminal	Circuit Role	Design Meaning
1 (Gate)	Control input	Receives negative gate drive signal; requires stable −10 V bias for full enhancement and minimal R_DS(on).
2 (Drain)	High-side power output	Connected to load supply rail; electrically tied to exposed metal pad for low-inductance heat path to PCB copper.
3 (Source)	Reference node	Connected to system ground or controller reference; defines gate-to-source voltage for channel control.

Key Features

Feature	Design Value

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXTP10P10P	R_DS(on) = 0.18 Ω (higher), Q_g = 45 nC (higher), TO-220 package (larger footprint, higher thermal resistance).	Less suitable for space-constrained automotive modules; better for through-hole prototyping or legacy board upgrades.	Choose when TO-220 mounting is required and 0.04 Ω R_DS(on) penalty is acceptable for cost-sensitive industrial controls.
SPB10P10PL	R_DS(on) = 0.135 Ω (slightly lower), but V_DSS = −100 V same; TO-252 package; not AEC-Q101 qualified.	Lacks automotive qualification; limited to non-safety-critical industrial or consumer applications.	Prefer for cost-driven non-automotive designs where qualification testing is not mandated.

Compared with IXTP10P10P and SPB10P10PL, RD100P-T1-AZ delivers optimal balance of automotive qualification, thermal efficiency in DPAK, and gate drive compatibility-making it the preferred choice for new AEC-compliant high-side switching designs where board area and reliability are prioritized.

FAQ

What is the maximum junction temperature rating for RD100P-T1-AZ?

The RD100P-T1-AZ has a maximum rated junction temperature of +175 °C, validated per AEC-Q101 stress tests. This enables deployment in under-hood automotive locations where ambient temperatures exceed 125 °C. Derating curves in the official RD100P-T1-AZ datasheet specify allowable current versus case temperature to maintain safe operation below this limit.

Does RD100P-T1-AZ support gate drive from a standard 3.3 V microcontroller?

No-RD100P-T1-AZ requires a negative gate-to-source voltage for full enhancement, with V_GS(th) ranging from −2.0 V to −4.0 V and R_DS(on) specified at V_GS = −10 V. A 3.3 V MCU output cannot directly drive it; an inverting gate driver or level-shifting circuit generating −5 V to −10 V is required for reliable operation of RD100P-T1-AZ.

Is RD100P-T1-AZ suitable for use in a half-bridge configuration?

Yes-RD100P-T1-AZ can serve as the high-side switch in a P-channel/N-channel or dual N-channel (with bootstrap) half-bridge. Its low Q_g/Q_gd ratio and fast t_rr minimize shoot-through risk and switching losses. However, proper dead-time control and gate drive isolation must be implemented to ensure safe commutation of RD100P-T1-AZ in such topologies.

What is the avalanche energy rating (E_AS) of RD100P-T1-AZ and how is it applied in design?

RD100P-T1-AZ is rated for E_AS = 120 mJ at T_J = 25 °C. This single-pulse avalanche capability allows the device to safely absorb inductive energy during load disconnection-such as in relay replacement or solenoid de-energization-without external clamping components. Designers must verify actual circuit energy using L·I²/2 and ensure it remains below the RD100P-T1-AZ E_AS derated curve.

How does the TO-252 package of RD100P-T1-AZ impact thermal performance compared to TO-220?

The TO-252 (DPAK) package of RD100P-T1-AZ offers lower thermal resistance from junction-to-board (R_θJB ≈ 3.5 °C/W) when mounted on ≥1 in² 2-oz copper, outperforming TO-220's typical R_θJC of 1.5 °C/W only if heatsinked. RD100P-T1-AZ leverages PCB copper as primary heatsink-ideal for dense automotive modules-whereas TO-220 relies on external metal heatsinks and adds height and weight.
