Product details

Overview

2PD601AQW from Nexperia is an NPN general purpose transistor in SOT323 (SC-70) package, rated for 50 V V_CEO, 100 mA I_C, and DC current gain (h_FE) of 160–260 (Group Q). It supports switching and amplification in compact consumer and industrial signal-path circuits with low saturation voltage (V_CEsat ≤ 250 mV at I_C = 100 mA, I_B = 10 mA).

For engineers reviewing the 2PD601AQW datasheet, 2PD601AQW pinout, 2PD601AQW application, or 2PD601AQW equivalent, key selection criteria include its SOT323 thermal resistance (R_th(j-a) = 625 K/W), f_T = 100 MHz transition frequency, and verified Group Q h_FE range - critical for bias-stable low-power amplifier stages and digital logic interface switching.

Technical Context

This discrete NPN bipolar junction transistor operates in linear or saturated mode depending on base drive. Its 60 V V_CBO and 6 V V_EBO ratings support robust operation in 5 V and 3.3 V logic-level interfacing, while low C_c = 3 pF enables stable high-frequency small-signal performance up to 100 MHz.

The device is optimized for surface-mount assembly using reflow only, with thermal derating defined for SOT323 mounting conditions. Its 200 mW P_tot at T_amb ≤ 25 °C and 150 °C maximum junction temperature align it with space-constrained industrial control and portable electronics where thermal margin is constrained.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	50 V - Maximum collector-emitter voltage before breakdown; defines safe operating range in common-emitter switch configurations.
I_C (DC)	100 mA - Continuous collector current handling; suitable for driving LEDs, small relays, or logic buffers.

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
BC846B,215	Same SOT323 package; h_FE = 200–450 (Group B); higher f_T = 100 MHz; identical V_CEO/I_C ratings.	Broader h_FE spread may require wider base-resistor tolerance in precision bias designs.	Select when tighter h_FE binning is not required and higher gain variability is acceptable.
MMBT3904LT1G	SOT23 package (larger footprint); h_FE = 100–300; V_CEO = 40 V; P_tot = 310 mW; R_th(j-a) = 405 K/W.	Lower V_CEO limits use in 48 V tolerant circuits; higher power rating suits higher ambient temperature environments.	Select when board layout allows SOT23 and 40 V rating suffices for target supply rails.

Compared with BC846B,215 and MMBT3904LT1G, the 2PD601AQW offers tighter h_FE control (160–260) and superior thermal resistance matching for SOT323-constrained designs, making it preferred for miniaturized, thermally sensitive applications requiring predictable gain behavior.

FAQ

What is the package type and lead count of the 2PD601AQW?

The 2PD601AQW uses the SOT323 (SC-70) plastic surface-mounted package with three leads. Its dimensions are 1.35 mm × 1.15 mm × 0.95 mm, and it is qualified for reflow soldering only. This compact footprint supports high-density PCB layouts in portable and space-limited applications where the 2PD601AQW delivers reliable NPN switching performance.

What is the guaranteed DC current gain (h_FE) range for the 2PD601AQW?

The 2PD601AQW is binned into Group Q, with a guaranteed h_FE range of 160 to 260 when measured at I_C = 2 mA and V_CE = 10 V. This tight gain specification enables predictable base-current design in bias networks, reducing calibration overhead in production for circuits relying on the 2PD601AQW as a linear amplifier or saturated switch.

Does the 2PD601AQW support reflow soldering, and what are the thermal limitations?

Yes, reflow soldering is the only recommended method for the 2PD601AQW. Its thermal resistance from junction to ambient is 625 K/W under standard SOT323 mounting conditions. With a total power dissipation limit of 200 mW at T_amb ≤ 25 °C and a maximum junction temperature of 150 °C, the 2PD601AQW requires careful thermal derating above ambient - especially in sealed enclosures where airflow is restricted.

What is the maximum collector-emitter voltage (V_CEO) rating for the 2PD601AQW?

The 2PD601AQW has a maximum V_CEO rating of 50 V, specified under open-base conditions. This rating defines the upper limit for collector-to-emitter voltage in common-emitter configurations and provides a 2× safety margin over typical 24 V industrial control rails. Exceeding this value risks permanent breakdown and must be avoided in all operating conditions of the 2PD601AQW.

How does the 2PD601AQW compare to the 2PD601ARW and 2PD601ASW variants?

The 2PD601AQW, 2PD601ARW, and 2PD601ASW share identical SOT323 packaging and electrical ratings (V_CEO, I_C, f_T, etc.), differing only in DC current gain binning: Q (160–260), R (210–340), and S (290–460). Designers select the 2PD601AQW when moderate, tightly controlled gain is required - for example, in feedback-stable amplifier stages or deterministic digital switching where excessive h_FE could cause unintended latch-up or timing skew.
