Product details
Overview
PBSS5220T-QR from Nexperia is a PNP low VCEsat transistor in SOT23 package, rated for −20 V VCEO, −2 A continuous collector current, and 113 mΩ RCEsat at −2 A/−200 mA drive; used as high-efficiency switching element in automotive DC-DC converters and LED drivers.
For engineers reviewing the PBSS5220T-QR datasheet, PBSS5220T-QR pinout, PBSS5220T-QR application, or PBSS5220T-QR equivalent, this page delivers verified electrical parameters, validated SOT23 terminal mapping, automotive-grade thermal limits, and real-world use cases in supply-line switching and inductive load control.
Technical Context
This PNP bipolar junction transistor operates with base-controlled saturation switching, optimized for low-loss conduction in low-voltage (≤5 V) systems. Its −225 mV VCEsat at −2 A and −1.1 V VBEsat enable minimal voltage drop and reduced power dissipation in high-current switching paths.
Qualified to AEC-Q101, it supports operation from −65 °C to +150 °C junction temperature and delivers stable hFE ≥150 at −2 A/−100 mA drive. Thermal resistance Rth(j-a) is 260 K/W on FR4 with 1 cm² collector pad, enabling reliable performance in space-constrained automotive PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −20 V - Maximum safe collector-emitter blocking voltage with open base; defines maximum supply rail compatibility. |
| IC | −2 A - Continuous DC collector current rating; supports robust load switching without derating at Tamb ≤ 25 °C. |
| VCEsat | −225 mV - Measured at IC = −2 A, IB = −100 mA, pulsed; enables <0.5 W conduction loss in 2 A loads. |
| RCEsat | 113 mΩ - Equivalent on-resistance derived from VCEsat/IC; critical for calculating I²R heating in battery-powered circuits. |
| hFE | ≥150 - DC current gain at IC = −2 A, VCE = −2 V; ensures sufficient drive margin with standard logic-level base drivers. |
| Tj max | +150 °C - Absolute maximum junction temperature; allows operation in under-hood automotive environments. |
| Ptot | 480 mW - Total power dissipation on FR4 with optimized collector pad; sets practical thermal ceiling for SOT23 layout. |
Pinout & Package
SOT23 plastic surface-mount package: 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch, standardized footprint per Fig. 12–13 of Nexperia datasheet v.2 (22 June 2022).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control input requiring −100 mA to fully saturate at −2 A collector current; polarity-sensitive for PNP turn-on. |
| 2 | Emitter (E) | Common reference node tied to higher potential rail; carries full load current and must be routed with low-inductance copper. |
| 3 | Collector (C) | Switched output node connected to load; thermally enhanced via 1 cm² copper pad per datasheet condition [2]. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCEsat | −225 mV at −2 A enables >95% efficiency in 3.3 V supply-line switches, reducing thermal stress on adjacent components. |
| AEC-Q101 qualification | Validated for automotive applications including engine control modules and body electronics per stress test protocol. |
| High IC/ICM | −2 A continuous / −3 A peak rating supports driving relays, buzzers, and small DC motors without external buffering. |
| Thermal robustness | Rth(j-a) = 260 K/W with optimized pad allows sustained 1.5 A operation at 70 °C ambient without heatsink. |
| Small-footprint SOT23 | Enables high-density placement in space-limited modules such as LED driver boards and portable battery chargers. |
Applications
| DC-to-DC Conversion | Supply Line Switching |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP low-VCEsat transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMT3005LPSQ-13 | N-channel MOSFET (30 V, −5 A), requires level-shifting gate drive; RDS(on) = 42 mΩ @ VGS = −10 V. | Not directly compatible due to N-channel topology; needs inverted control signal and gate driver. | Select when higher efficiency at >1 A and lower VGS drive capability exist; avoid if only 3.3 V logic is available. |
| BC807-25Q-7-F | PNP BJT (45 V, −500 mA), VCEsat = −300 mV @ −500 mA; hFE = 160–400; not AEC-Q101 qualified. | Limited to ≤500 mA loads; lacks automotive qualification and thermal robustness for under-hood use. | Acceptable for non-automotive consumer DC-DC stages where current and reliability requirements are lower. |
Compared with PBSS5220T-QR, DMT3005LPSQ-13 offers lower on-resistance but demands gate-level translation, while BC807-25Q-7-F provides higher hFE spread but cannot sustain 2 A loads or meet automotive qualification-making PBSS5220T-QR the optimal balance of current, saturation voltage, and AEC compliance.

FAQ
What is the maximum allowable base current for PBSS5220T-QR?
The absolute maximum base current is −300 mA per Table 5 of the datasheet. However, for reliable saturation at −2 A collector current, −100 mA base drive is specified in the Characteristics table, yielding VCEsat = −225 mV. Exceeding −100 mA provides diminishing returns and risks localized heating without improving switching speed significantly.
Can PBSS5220T-QR replace a standard PNP transistor like BC857 in an existing design?
Yes, but only if the original design operates below −2 A and does not rely on higher VCEO than −20 V. PBSS5220T-QR offers lower VCEsat (−225 mV vs. typical −600 mV for BC857 at −100 mA), improved thermal performance, and AEC-Q101 qualification-making it superior for automotive upgrades, though PCB layout must accommodate SOT23 pinout alignment.
Is PBSS5220T-QR suitable for PWM-driven LED backlighting?
Yes. Its −225 mV VCEsat at −2 A and 100 MHz fT support clean switching at PWM frequencies up to 20 kHz without significant rise/fall time degradation. The device's −150 °C to +150 °C operating range and low thermal resistance ensure stable brightness control in dashboard LCD modules exposed to wide ambient swings.
Does PBSS5220T-QR require a heatsink in typical automotive applications?
No external heatsink is required when mounted on FR4 with a 1 cm² copper pad on the collector terminal, as confirmed by Rth(j-a) = 260 K/W in that configuration. At 1.5 A continuous current and 70 °C ambient, junction temperature remains below 125 °C-well within the +150 °C limit-provided solder mask openings and thermal vias follow Nexperia's recommended footprint (Fig. 12).
