Product details

Overview

PBSS5220T,215 from Nexperia is a PNP low-V_CEsat transistor in SOT23 package, rated for −20 V V_CEO, −2 A continuous collector current, and 113 mΩ R_CEsat at −2 A/−200 mA drive-designed for high-efficiency switching in battery-powered DC-DC converters and LED drivers.

For engineers reviewing the PBSS5220T,215 datasheet, PBSS5220T,215 pinout, PBSS5220T,215 application, or PBSS5220T,215 equivalent, this device is selected for low-loss PNP switching where V_CEsat ≤ −250 mV at full load, thermal resistance < 260 K/W on FR4, and SOT23 footprint compatibility with space-constrained portable designs.

Technical Context

This PNP bipolar junction transistor operates in saturation mode for efficient low-side switching, with guaranteed h_FE ≥ 150 at −2 A/−100 mA drive and V_BEsat = −1.1 V under same conditions. Its low R_CEsat enables minimal conduction loss in battery charger and backlighting circuits.

The device features absolute maximum ratings of −20 V V_CEO, −3 A I_CM (1 ms pulse), and 150 °C T_j, with thermal resistance as low as 260 K/W when mounted on FR4 with 1 cm² collector pad-supporting reliable operation in thermally constrained consumer and industrial modules.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−20 V: Maximum safe collector-emitter voltage with base open; defines off-state blocking capability in supply-line switches.
I_C	−2 A continuous: Rated DC collector current; supports sustained 2 A load switching without derating at T_amb ≤ 25 °C.
R_CEsat	113 mΩ at −2 A/−200 mA: Equivalent on-resistance determining conduction loss (P_cond ≈ I² × R) in saturated switching.
V_CEsat	−225 mV max at −2 A/−100 mA: Confirmed saturation voltage enabling < 0.5 W dissipation at full current in compact layouts.
h_FE	150 min at −2 A/−100 mA: Ensures sufficient DC gain to achieve full saturation with modest base drive, reducing driver complexity.
f_T	100 MHz: Transition frequency confirming usable bandwidth for PWM frequencies up to ~10 MHz with gain margin.

Pinout & Package

SOT23 plastic surface-mount package: 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch, standard footprint compatible with automated reflow assembly.

Pin/Terminal	Circuit Role	Design Meaning
1 - B	Base	Control terminal requiring −100 mA to fully saturate at −2 A collector current; polarity-sensitive for PNP biasing.
2 - E	Emitter	Common reference node tied to higher potential rail; carries full load current and must be routed with low-inductance path.
3 - C	Collector	Switched output terminal connected to load; thermal pad design requires 1 cm² copper area for 260 K/W R_th(j-a).

Key Features

Feature	Design Value
Low V_CEsat	−225 mV max ensures < 0.45 W conduction loss at −2 A, reducing thermal load in sealed enclosures.
High I_C capability	−2 A continuous rating enables direct driving of 2 A loads (e.g., LED strings or relay coils) without external amplification.
Optimized R_CEsat	113 mΩ enables precise power loss modeling in battery-operated systems where every milliwatt affects runtime.
SOT23 footprint	Standard 3-pin SMT outline allows drop-in replacement in existing layouts and compatibility with high-volume pick-and-place equipment.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP low-V_CEsat transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMT3005LPS-7	−30 V V_CEO, −3.5 A I_C, 75 mΩ R_CEsat, SOT23-3L package with exposed drain pad.	Higher voltage/current rating and lower R_CEsat, but requires thermal pad layout and has different pinout (G-S-D vs B-E-C).	Select when >−20 V blocking or <100 mΩ R_CEsat is required; verify PCB land pattern compatibility.
BC807-25,215	−45 V V_CEO, −500 mA I_C, 300 mΩ R_CEsat, same SOT23 package and pinout.	Lower current capability and higher V_CEsat; suitable only for sub-500 mA loads where voltage headroom >−20 V is needed.	Select for cost-sensitive, low-power applications where −2 A rating is unnecessary and higher V_CEO adds margin.

Compared with DMT3005LPS-7 and BC807-25,215, PBSS5220T,215 delivers optimal balance of −2 A current handling, −225 mV V_CEsat, and standard SOT23 pinout-making it ideal for mid-power portable electronics where thermal and layout constraints preclude larger packages or non-standard footprints.

FAQ

What is the maximum allowable base current for continuous operation?

The absolute maximum base current is −300 mA per datasheet limiting values. For reliable continuous operation at −2 A collector current, the recommended base drive is −100 mA (IC/IB = 20), ensuring full saturation while maintaining junction temperature within 150 °C limit on standard FR4 PCB.

Can PBSS5220T,215 replace an NPN transistor in the same circuit?

No-it is a PNP device with opposite polarity: emitter connects to higher potential, collector to load ground side. Direct substitution would invert logic and likely cause malfunction. Circuit redesign is required to accommodate PNP switching topology and base drive polarity.

Is PBSS5220T,215 qualified for automotive applications?

No-the 2023 datasheet explicitly states this variant is non-automotive qualified. It lacks AEC-Q101 stress testing and qualification. For automotive use, Nexperia offers the −Q qualified version (e.g., PBSS5220T,215-Q), which undergoes extended temperature and reliability validation.

What is the thermal resistance when using standard SOT23 footprint without extended copper?

With standard single-sided FR4 footprint (no extended collector pad), R_th(j-a) is 417 K/W per datasheet Table 6. This results in ~84 °C junction rise at −2 A with −225 mV V_CEsat (0.45 W dissipation), requiring ambient ≤ 66 °C for safe 150 °C T_j margin.
