Product details

Overview

2PD602ASL-QR from Nexperia is an AEC-Q101-qualified NPN general-purpose transistor in SOT23 package, rated for 50 V V_CEO, 500 mA I_C, and 170–340 h_FE at 150 mA. It serves as a switching or amplification element in automotive signal conditioning and power control stages, with 600 mV V_CE(sat) at 300 mA/30 mA drive.

For engineers reviewing the 2PD602ASL-QR datasheet, 2PD602ASL-QR pinout, 2PD602ASL-QR application, or 2PD602ASL-QR equivalent, key selection criteria include automotive qualification status, SOT23 thermal resistance (500 K/W), DC current gain spread, V_CE(sat) performance under pulsed conditions, and junction temperature limit of 150 °C.

Technical Context

This discrete NPN bipolar junction transistor operates in linear or saturated switching modes, with base-emitter forward bias enabling controlled collector current flow up to 500 mA continuous and 1 A peak. Its 180 MHz f_T supports medium-frequency amplification tasks.

The device features AEC-Q101 qualification per stress test standards for discrete semiconductors, validated across −55 °C to +150 °C ambient range and 150 °C junction limit. Thermal resistance of 500 K/W (FR4 PCB, single-sided copper) defines its power derating behavior.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	50 V - Maximum safe collector-emitter voltage with base open; sets upper rail limit for switching applications
I_C	500 mA - Continuous collector current rating; determines load-driving capability in relay drivers or LED switches
h_FE	170–340 - DC current gain at V_CE = 10 V, I_C = 150 mA; defines base drive requirement for saturation
V_CE(sat)	≤600 mV - Collector-emitter voltage drop at I_C = 300 mA, I_B = 30 mA; directly impacts conduction loss and thermal rise
f_T	180 MHz - Transition frequency at V_CE = 10 V, I_C = 50 mA; indicates usable bandwidth for small-signal amplification
R_th(j-a)	500 K/W - Junction-to-ambient thermal resistance on FR4 PCB; governs maximum power dissipation at given ambient temperature

Pinout & Package

SOT23 plastic surface-mounted package: 3-terminal, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body. Compliant with JEDEC TO-236AB outline.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Control terminal; requires ~30 mA drive to saturate at 300 mA collector load
2	Emitter (E)	Current return path; connected to ground or low-side reference in common-emitter configurations
3	Collector (C)	Output terminal; handles switched load current up to 500 mA with ≤600 mV drop when fully driven

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive use per stress test standard; enables deployment in engine control, body electronics, and ADAS subsystems
SOT23 footprint compatibility	Standard 1.9 mm pitch layout supports automated placement and reflow soldering on high-density PCBs
Low V_CE(sat)	≤600 mV ensures <180 mW conduction loss at 300 mA, reducing thermal load in space-constrained modules
150 °C junction rating	Enables operation in under-hood environments without derating below 100 °C ambient

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN general-purpose transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC847BW	Same SOT23 package; h_FE 200–450, V_CEO = 45 V, no AEC-Q101 qualification	Not qualified for automotive; suitable for commercial-grade consumer or industrial boards	Select when AEC-Q101 is not required and higher h_FE tolerance is acceptable
MMBT3904LT1G	V_CEO = 40 V, I_C = 200 mA, h_FE 100–300, AEC-Q101 qualified	Lower voltage/current ratings limit use to low-power signal paths only	Choose where 40 V/200 mA suffices and cost sensitivity outweighs performance margin

Compared with BC847BW and MMBT3904LT1G, the 2PD602ASL-QR uniquely combines AEC-Q101 compliance, 50 V/500 mA ratings, and low 600 mV saturation voltage-making it optimal for automotive load switching where reliability, headroom, and thermal efficiency are jointly critical.

FAQ

Is the 2PD602ASL-QR suitable for linear amplification applications?

Yes. With a transition frequency (f_T) of 180 MHz and DC current gain (h_FE) of 170–340 at 150 mA, it supports stable small-signal amplification up to several hundred kHz. Its low noise and consistent gain across temperature make it appropriate for sensor front-end stages where precision biasing is maintained.

What is the maximum allowable power dissipation at 85 °C ambient temperature?

At 85 °C ambient, the maximum allowable power dissipation is 130 mW. This is derived from the 500 K/W thermal resistance and the 150 °C maximum junction temperature: P_tot = (T_j(max) − T_amb) / R_th(j-a) = (150 − 85) / 500 = 0.13 W. Derating applies above 25 °C ambient per the datasheet curve.

Does the 2PD602ASL-QR support pulse-width modulation (PWM) drive?

Yes. The device is characterized under pulsed conditions (t_p ≤ 300 µs, duty cycle δ ≤ 0.02), confirming suitability for PWM-driven loads such as LED dimming or solenoid control. Its fast switching speed and low V_CE(sat) minimize switching losses and thermal stress during repetitive on/off cycling.

How does the marking code 'SF%' correspond to the full part number?

The marking code 'SF%' appears on the top surface of the SOT23 package, where '%' is a placeholder for the manufacturing site code (e.g., 'SFA' for one facility). This matches the official ordering code 2PD602ASL-Q and confirms authenticity per Nexperia's traceability system and AEC-Q101 qualification documentation.
