Product details

Overview

2PD602ASL from Nexperia is an NPN general-purpose bipolar junction transistor in SOT23 package, rated for 50 V V_CEO, 500 mA I_C, and 250 mW P_tot, with DC current gain (h_FE) of 170–340 at 150 mA. It serves as a low-voltage switching and linear amplification device in compact consumer and industrial PCBs.

For engineers reviewing the 2PD602ASL datasheet, 2PD602ASL pinout, 2PD602ASL application, or 2PD602ASL equivalent, key selection criteria include its V_CEO/I_C rating, SOT23 thermal resistance (500 K/W), h_FE spread, V_CE(sat) ≤ 600 mV at 300 mA/30 mA drive, and suitability for non-automotive general-purpose discrete use.

Technical Context

The 2PD602ASL operates as a silicon-based NPN BJT optimized for DC and low-frequency switching up to ~180 MHz f_T, with base-emitter turn-on voltage ~0.7 V and collector-base breakdown at 60 V. Its pulsed test conditions (t_p ≤ 300 µs, δ ≤ 0.02) define h_FE and V_CE(sat) specifications under controlled thermal duty cycle.

Thermal performance is specified for FR4 PCB mounting (single-sided copper, tin-plated), yielding R_th(j-a) = 500 K/W - a critical constraint for sustained 250 mW dissipation. Device operation is limited to T_amb = –55 °C to +150 °C and T_j ≤ 150 °C, with non-automotive qualification confirmed per revision history.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	50 V - maximum safe collector-emitter voltage with base open; defines upper rail limit in switch applications
I_C	500 mA - continuous collector current rating; sets max load-handling capacity in linear or saturated mode
h_FE	170–340 - DC current gain at V_CE = 10 V, I_C = 150 mA; determines required base drive for target collector current
V_CE(sat)	≤ 600 mV - saturation voltage at I_C = 300 mA, I_B = 30 mA; directly impacts conduction loss and heat generation
P_tot	250 mW - total power dissipation at T_amb ≤ 25 °C on standard FR4; constrains usable I²R and V×I operating envelope
f_T	180 MHz - transition frequency at V_CE = 10 V, I_C = 50 mA; indicates usable bandwidth for small-signal amplification
C_c	15 pF - collector capacitance at V_CB = 10 V; affects high-frequency response and switching speed

Pinout & Package

SOT23 plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body, designed for reflow and wave soldering per IPC-7351B footprint standards.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Current-controlled input node; requires sufficient I_B to saturate or bias transistor in active region
2	Emiter (E)	Common reference terminal for both input and output circuits; connected to ground or low-side return path
3	Collector (C)	Output current terminal; carries full load current when switched; connects to positive supply or load high side

Key Features

Feature	Design Value
General-purpose NPN architecture	Enables dual-mode use in both linear amplification (active region) and digital switching (saturation/cutoff)
SOT23 footprint compatibility	Supports high-density PCB layouts and automated assembly without requiring custom land patterns
180 MHz transition frequency	Permits stable small-signal gain up to mid-VHF range, suitable for oscillator and RF detector stages
Low V_CE(sat) (≤ 600 mV)	Reduces conduction losses and self-heating during switching, improving efficiency in battery-powered loads
Non-automotive qualification	Validated for industrial, consumer, and computing applications - excludes AEC-Q101 stress testing and automotive lifecycle requirements

Applications

LED Driver Circuit

Microcontroller GPIO Expander

Use Scenario: Driving 20–50 mA indicator LEDs from 3.3 V or 5 V logic rails using MCU GPIO pins with limited current sourcing capability.

IC Role / Device Role / Timing Role: Low-side switch that translates logic-level signals into higher-current LED paths while isolating MCU I/O from load transients.

Use Value: Enables direct GPIO control without external level-shifting or buffering; V_CE(sat) ≤ 600 mV ensures minimal voltage drop across transistor, preserving LED forward voltage margin.

Use Scenario: Extending digital output capability of resource-constrained microcontrollers (e.g., 8-bit MCUs with <16 GPIOs) to drive relays, solenoids, or multiple peripheral enable lines.

IC Role / Device Role / Timing Role: Discrete current amplifier stage that converts weak MCU output (≤ 20 mA) into robust 300–500 mA capable of energizing electromechanical loads.

Use Value: Provides scalable, low-cost I/O expansion without dedicated port expanders; h_FE ≥ 170 ensures reliable saturation with typical MCU drive levels.

DC-DC Converter Feedback

Signal Level Shifting

Use Scenario: Providing optocoupler-coupled feedback signal conditioning in isolated flyback or forward converters operating at ≤ 500 kHz switching frequency.

IC Role / Device Role / Timing Role: Linear-region amplifier translating error amplifier output into optocoupler LED drive current with stable gain and temperature-invariant bias.

Use Value: h_FE consistency over 25 °C and low C_c (15 pF) support accurate, phase-stable feedback loop response without added compensation complexity.

Use Scenario: Bidirectional level translation between 1.8 V logic (sensor interface) and 3.3 V microcontroller domains where direction control is managed externally.

IC Role / Device Role / Timing Role: Active pull-up/pull-down element enabling voltage domain bridging with fast edge integrity and minimal propagation delay.

Use Value: f_T = 180 MHz supports clean transitions up to ~10 MHz data rates; low V_BE(on) (~0.7 V) ensures predictable turn-on threshold across process variation.

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	V_CEO = 65 V, h_FE = 200–450, P_tot = 300 mW, same SOT23 package	Higher voltage headroom and power rating; wider h_FE spread may require tighter base resistor tolerance	Preferred where system rail exceeds 50 V or ambient derating demands >250 mW dissipation
MMBT3904LT1G	V_CEO = 40 V, h_FE = 100–300, P_tot = 310 mW, same SOT23 package	Lower V_CEO limits use to ≤40 V systems; narrower h_FE range simplifies bias design but reduces max gain	Selected when cost sensitivity outweighs voltage margin needs and gain consistency is prioritized over peak performance

Compared with BC846B,215 and MMBT3904LT1G, the 2PD602ASL offers balanced V_CEO/I_C ratings and mid-range h_FE ideal for 3.3–5 V embedded switching, whereas BC846B suits higher-voltage designs and MMBT3904LT1G favors cost-driven 40 V-class applications.

FAQ

Is the 2PD602ASL qualified for automotive applications?

No. Per the 2023 revision history, the 2PD602ASL is explicitly designated as non-automotive. It lacks AEC-Q101 qualification, automotive-grade screening, and extended temperature validation beyond its specified –55 °C to +150 °C ambient range. Automotive designs must select variants marked with "-Q" suffixes such as 2PD602AQ.

What is the maximum continuous collector current at 85 °C ambient?

At T_amb = 85 °C, the 2PD602ASL's usable I_C is thermally derated from 500 mA. With R_th(j-a) = 500 K/W and T_j(max) = 150 °C, the allowable ΔT = 65 K, limiting P_tot to 130 mW. Assuming V_CE(sat) ≈ 0.6 V, max continuous I_C ≈ 217 mA - verified by Nexperia's thermal derating curves in the full datasheet.

Can the 2PD602ASL replace a BC547 in existing designs?

Direct replacement is possible only if the BC547's V_CEO (45 V) and I_C (100 mA) requirements are within the 2PD602ASL's 50 V/500 mA ratings and SOT23 footprint matches the PCB layout. However, h_FE spread differs (BC547: 110–800 vs. 2PD602ASL: 170–340), so base resistor values may need adjustment to ensure saturation under identical load conditions.

Does the 2PD602ASL have built-in ESD protection?

No. The datasheet does not specify human-body model (HBM) or charged-device model (CDM) ESD ratings. As a standard general-purpose BJT, it lacks integrated protection structures. External series resistors and TVS diodes are recommended in handling and circuit design when exposed to environments with >2 kV HBM risk.
