Product details

Overview

2PB710ASL,235 from Nexperia is a PNP general-purpose bipolar junction transistor in SOT23 package, rated for −50 V V_CEO, −500 mA I_C, with DC current gain (h_FE) of 170–340 at −150 mA, used for low-voltage switching and linear amplification in consumer power management circuits.

For engineers reviewing the 2PB710ASL,235 datasheet, 2PB710ASL,235 pinout, 2PB710ASL,235 application, or 2PB710ASL,235 equivalent, key selection criteria include verified PNP polarity, SOT23 footprint compatibility, −600 mV V_CEsat at −300 mA, thermal resistance of 500 K/W on FR4 PCB, and non-automotive qualification status per revision v.3 (July 2023).

Technical Context

This discrete PNP BJT operates in active or saturation mode with base-controlled collector current flow. Its design supports pulsed operation (t_p ≤ 300 µs, duty δ ≤ 0.02) and specifies V_BEsat = −1.5 V at −30 mA I_B, enabling predictable drive requirements in digital logic interfacing.

Thermal performance is defined for standard FR4 PCB mounting (single-sided copper, tin-plated), with T_j max = 150 °C and P_tot = 250 mW at T_amb ≤ 25 °C. Cut-off leakage (I_CBO ≤ −5 µA at 150 °C) ensures stable off-state behavior in temperature-varying environments.

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 PNP switch designs.
I_C	−500 mA continuous: Rated collector current capacity; sets load-driving capability in relay drivers or LED sinks.
h_FE	170–340 at −150 mA: DC current gain range under pulsed conditions; determines required base drive for target collector current.
V_CEsat	−600 mV max at −300 mA: Saturation voltage defining conduction loss and heat generation in switching applications.
f_T	140 MHz: Transition frequency indicating usable bandwidth for small-signal amplification up to mid-RF range.
R_th(j-a)	500 K/W: Junction-to-ambient thermal resistance on standard FR4; informs derating needed above 25 °C ambient.
P_tot	250 mW at T_amb ≤ 25 °C: Total power dissipation limit; constrains simultaneous voltage/current operation in thermal-limited layouts.

Pinout & Package

SOT23 plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body, optimized for automated reflow assembly on FR4 PCBs.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Current-controlled input node; requires −30 mA peak drive for full saturation at −300 mA collector load.
2	Emitter (E)	Common terminal for PNP configuration; connected to higher potential rail in high-side switch topologies.
3	Collector (C)	Output current path; sinks load current to ground or lower-potential node when base is biased.

Key Features

Feature	Design Value
PNP polarity with verified −50 V rating	Enables high-side switching in 3.3 V/5 V logic-controlled power rails without level-shifting circuitry.
SOT23 footprint compatibility	Supports high-density PCB layouts and standard pick-and-place assembly; matches JEDEC TO-236AB outline.
140 MHz f_T and 15 pF C_c	Permits use in audio preamplifier stages and low-noise signal conditioning up to ~10 MHz bandwidth.
−600 mV V_CEsat at −300 mA	Reduces conduction loss to <180 mW in saturated switching, easing thermal management in space-constrained modules.

Applications

LED Driver Circuit

Microcontroller GPIO Expander

Use Scenario: Driving multiple 20 mA indicator LEDs from 3.3 V microcontroller outputs via common-anode configuration.

IC Role / Device Role / Timing Role: PNP current sink switch controlled by inverted GPIO signal; provides rail-referenced on/off control.

Use Value: Low V_CEsat minimizes LED forward voltage drop impact; h_FE ≥ 170 ensures reliable turn-on with ≤2 mA base drive.

Use Scenario: Extending limited GPIO count to control external peripherals like sensors or displays using discrete logic-level translation.

IC Role / Device Role / Timing Role: Level-shifting buffer for 1.8 V/3.3 V domain interfacing; operates in active region for analog signal buffering.

Use Value: 140 MHz f_T supports clean signal integrity up to 10 MHz clocked interfaces; low C_c prevents capacitive loading distortion.

DC-DC Converter Bias Network

Low-Power Sensor Signal Amplifier

Use Scenario: Providing bias current to error amplifier or reference circuitry in compact buck converter ICs operating from 5 V input.

IC Role / Device Role / Timing Role: Precision current source configured with emitter resistor; delivers stable −100 µA to −1 mA bias current.

Use Value: Tight h_FE tolerance (170–340) and low I_CBO (<−10 nA at 25 °C) ensure stable bias over temperature and time.

Use Scenario: Amplifying thermistor or photodiode output signals in battery-powered environmental monitoring nodes.

IC Role / Device Role / Timing Role: Single-stage common-emitter amplifier with emitter degeneration; provides 20–40 dB voltage gain at DC–1 MHz.

Use Value: 250 mW P_tot and 500 K/W R_th(j-a) allow continuous operation at <40 °C ambient with no heatsink in sealed enclosures.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC807-40,215	Same SOT23 package; h_FE = 250–600 at −100 mA; V_CEO = −45 V; slightly lower voltage rating.	Marginally reduced headroom in 50 V systems; otherwise identical switching/amplification use cases.	Select when higher h_FE consistency is prioritized over absolute V_CEO margin.
MMBT3906LT1G	Same SOT23; V_CEO = −40 V; I_C = −200 mA; h_FE = 100–300; lower current and voltage ratings.	Not suitable for >−200 mA loads or >−40 V rails; acceptable only in low-power signal paths.	Choose only for cost-sensitive, low-current signal buffering where 500 mA capability is unnecessary.

Compared with BC807-40,215 and MMBT3906LT1G, the 2PB710ASL,235 offers superior voltage margin (−50 V), higher current handling (−500 mA), and tighter thermal resistance spec (500 K/W), making it optimal for robust 5 V–12 V power switching where reliability across temperature extremes is critical.

Manufacturer

Nexperia is a global semiconductor expert focused on high-volume, high-reliability discrete and logic devices, with manufacturing rooted in process optimization and automotive-grade quality systems.

The 2PB710ASL belongs to Nexperia's general-purpose bipolar transistor product line, designed for cost-effective, space-efficient switching and amplification in consumer, industrial, and computing applications-not qualified for automotive use per revision v.3.

FAQ

Is the 2PB710ASL,235 qualified for automotive applications?

No. Per the July 2023 revision history, this part was explicitly changed to non-automotive qualification. Automotive alternatives-such as the −Q qualified 2PB710AXL series-are documented separately on Nexperia's website and require distinct part numbering and qualification testing.

What is the maximum allowable base current for continuous operation?

The absolute maximum peak base current is −200 mA (single pulse, t_p ≤ 1 ms), but continuous I_B must be limited by thermal constraints. At T_amb = 25 °C, P_tot = 250 mW limits I_B to ≤ −10 mA when V_BE ≈ −0.75 V, assuming typical forward voltage and negligible collector power contribution.

Can the 2PB710ASL,235 replace a 2N3906 in existing designs?

Yes, with verification. Both are PNP SOT23 transistors, but the 2PB710ASL,235 has higher I_C (−500 mA vs. −200 mA), higher V_CEO (−50 V vs. −40 V), and higher f_T (140 MHz vs. 250 MHz). Layout compatibility is confirmed, but V_CEsat (−600 mV) differs from 2N3906 (−400 mV), affecting saturation loss.

Does the marking code 'SD%' indicate RoHS compliance?

Yes. Nexperia's standard marking convention-including 'SD%' for the 2PB710ASL-corresponds to RoHS-compliant, lead-free, halogen-free devices manufactured after 2006. Full compliance documentation (including REACH and conflict minerals statements) is available via Nexperia's product portal using the full type number.
