Product details

Overview

2PD601ASL,235 from Nexperia is an AEC-Q101-qualified NPN general-purpose transistor in SOT23 (TO-236AB) package, rated for 50 V V_CEO, 100 mA I_C, and h_FE group S (290–460 at V_CE = 10 V, I_C = 2 mA), used for low-power switching and amplification in automotive body electronics.

For engineers reviewing the 2PD601ASL,235 datasheet, 2PD601ASL,235 pinout, 2PD601ASL,235 application, or 2PD601ASL,235 equivalent, key selection criteria include its halogen-free /DG variant compliance, dual h_FE binning (R/S), junction temperature rating up to 150 °C, and suitability for space-constrained PCB layouts requiring SOT23 footprint compatibility.

Technical Context

This discrete NPN bipolar junction transistor operates as a current-controlled switch or linear amplifier with fixed three-terminal topology. Its DC current gain is binned into two groups (R: 210–340; S: 290–460), enabling precise gain matching in analog front-ends or digital logic interface circuits.

Designed for automotive-grade reliability, it meets AEC-Q101 stress test requirements and supports operation across −55 °C to +150 °C ambient range. Thermal resistance R_th(j-a) is 500 K/W on FR4 PCB, limiting continuous power dissipation to 250 mW at T_amb ≤ 25 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	50 V - Maximum collector-emitter voltage before breakdown under open-base condition; defines safe operating voltage in switching applications.
I_C	100 mA - Continuous collector current rating; sets upper bound for load drive capability in signal-level switching.
h_FE group S	290–460 - DC current gain at V_CE = 10 V, I_C = 2 mA; enables predictable base drive sizing for saturation in digital logic interfaces.
V_CE(sat)	250 mV max at I_C = 100 mA, I_B = 10 mA - Low saturation voltage ensures minimal conduction loss and heat generation in on-state operation.
f_T	100 MHz - Transition frequency at V_CE = 10 V, I_C = 2 mA, f = 100 MHz; supports small-signal amplification up to VHF band.
R_th(j-a)	500 K/W - Junction-to-ambient thermal resistance on standard FR4 PCB; determines required derating above 25 °C ambient.

Pinout & Package

The device uses a standard SOT23 (TO-236AB) plastic surface-mount package with 3 leads, optimized for automated placement and reflow soldering on high-density PCBs.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Current-controlled input terminal; requires ~10 mA base drive to saturate at 100 mA collector load.
2	Emitter	Common reference node for NPN configuration; connected to ground or low-side return path in switching circuits.
3	Collector	Output current terminal; handles up to 100 mA continuous load with 50 V standoff capability.

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive applications including body control modules and lighting drivers per stress test standard.
Two h_FE selections (R/S)	Enables design flexibility: group S (290–460) improves noise margin in logic-level interfacing; group R (210–340) reduces base drive demand.
Halogen-free /DG variant	Complies with RoHS and ELV directives; eliminates brominated flame retardants in package molding compound.
SOT23 footprint compatibility	Matches JEDEC TO-236AB mechanical outline; supports drop-in replacement with industry-standard pick-and-place tooling.

Applications

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
2PD601ARL,215	Same package and voltage/current ratings, but h_FE group R (210–340); non-halogen-free version.	Lower gain bin suits designs where reduced base drive current is prioritized over noise immunity.	Select when lower I_B requirement outweighs need for tighter gain tolerance or halogen-free compliance.
BC847BS,115	Same SOT23 package, 45 V V_CEO, 100 mA I_C, h_FE 200–450; not AEC-Q101 qualified.	Lacks automotive qualification; suitable for commercial-grade consumer or industrial equipment only.	Choose for cost-sensitive non-automotive applications where AEC-Q101 is not mandated.

Compared with 2PD601ARL,215 and BC847BS,115, the 2PD601ASL,235 offers higher guaranteed h_FE (290–460), halogen-free construction, and AEC-Q101 certification-making it optimal for automotive interior systems requiring robustness, gain consistency, and regulatory compliance.

FAQ

What is the marking code for 2PD601ASL,235?

The marking code for 2PD601ASL is "SK*", where "*" denotes country of origin: "-" or "p" = Hong Kong, "t" = Malaysia, "W" = China. This laser-marked code appears on the top surface of the SOT23 package and is used for traceability and bin identification (group S gain).

Is 2PD601ASL,235 suitable for linear amplification?

Yes - its specified h_FE (290–460), low V_CE(sat) (≤250 mV), and f_T of 100 MHz support stable small-signal amplification in common-emitter configurations. Operation must remain within limiting values: V_CE ≤ 50 V, I_C ≤ 100 mA, and P_tot ≤ 250 mW at T_amb ≤ 25 °C.

How does the /DG suffix affect performance?

The /DG suffix indicates halogen-free construction per IEC 61249-2-21, replacing brominated flame retardants in the epoxy mold compound. Electrical and thermal specifications-including V_CEO, h_FE, R_th(j-a), and AEC-Q101 qualification-are identical to non-/DG variants.

What is the maximum peak collector current rating?

The maximum peak collector current is 200 mA for single pulses with duration ≤1 ms. This rating applies under transient conditions such as inrush current limiting or short-duration switching events, and must be derated according to duty cycle and ambient temperature per thermal characteristics data.
