Product details
Overview
PBSS5320T,215 from Nexperia is a PNP low VCE(sat) transistor in SOT23 package, rated for −20 V VCEO, −2 A continuous IC, and −3 A pulsed ICRM. It delivers 75 mΩ typical RCE(sat) at −2 A/−200 mA drive, enabling high-efficiency switching in compact power management circuits such as battery chargers and LDO regulators.
For engineers reviewing the PBSS5320T,215 datasheet, PBSS5320T,215 pinout, PBSS5320T,215 application, or PBSS5320T,215 equivalent, key selection criteria include verified VCE(sat) ≤ 300 mV at −3 A, thermal resistance as low as 104 K/W under pulsed conditions, and confirmed SOT23 pin mapping with Base–Emitter–Collector on pins 1–2–3.
Technical Context
This PNP transistor operates as a low-loss switch in linear and switching power stages, leveraging its low saturation voltage to minimize conduction loss and heat generation. Its DC current gain (hFE) reaches 100 at −3 A, supporting robust base drive efficiency in high-current load control.
The device is characterized under pulsed conditions (tp ≤ 300 µs, δ ≤ 0.02) for RCE(sat) and VCE(sat), with thermal performance specified across three PCB mounting configurations-standard footprint, 1 cm² collector pad, and 6 cm² collector pad-to support real-world layout-dependent derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −20 V: Maximum safe collector-emitter blocking voltage with open base; defines upper limit for supply rail switching in 12 V systems. |
| IC (continuous) | −2 A: Continuous DC collector current rating; supports sustained load switching in DC/DC converters and battery charge paths. |
| ICRM (pulsed) | −3 A: Repetitive peak current capability under 100 ms pulses; enables short-term surge handling in startup or fault conditions. |
| RCE(sat) | 75–105 mΩ: Confirmed on-resistance at −2 A/−200 mA; directly determines conduction loss (P = I²R) and thermal rise in compact layouts. |
| VCE(sat) | ≤ 300 mV at −3 A/−300 mA: Verified saturation voltage under full-rated current; ensures < 0.3 V dropout in LDO pass elements or supply switches. |
| hFE | 100 min at −3 A: Minimum DC current gain under full load; guarantees sufficient base drive margin without excessive IB overhead. |
| Tj(max) | 150 °C: Absolute maximum junction temperature; sets thermal design boundary for ambient and PCB copper area requirements. |
Pinout & Package
Package: SOT23 (TO-236AB), surface-mounted plastic package, 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch, standard footprint per Fig. 12 (reflow) and Fig. 13 (wave).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control input requiring −300 mA max base current; polarity-sensitive for PNP turn-on; connects to driver IC or resistor network. |
| 2 | Emitter (E) | Common reference terminal tied to higher potential (e.g., input rail); carries full load current and defines VEB bias path. |
| 3 | Collector (C) | Switched output node; connects to load or ground return; thermally coupled to PCB copper for enhanced power dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) | ≤ 300 mV at −3 A ensures < 0.9 W conduction loss, reducing heatsink need in space-constrained 5–12 V power rails. |
| High current gain | hFE ≥ 100 at −3 A allows base drive current ≤ 30 mA, easing compatibility with microcontroller GPIO or logic-level drivers. |
| Low RCE(sat) | 75 mΩ typical enables < 0.3 W loss at −2 A, improving efficiency over standard PNP transistors by >40% in 1 A+ applications. |
| Thermal optimization | Rth(j-a) = 104 K/W under pulsed conditions supports reliable operation up to 1.2 W peak power with minimal PCB copper. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP low VCE(sat) transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS40201MZ4T1G | VCEO = −20 V, IC = −2 A, RCE(sat) = 110 mΩ typ at −1 A; SOT-23 package, same pinout. | Higher RCE(sat) increases conduction loss by ~45% at −2 A; lower hFE (60 min) demands stronger base drive. | Select when cost sensitivity outweighs efficiency needs and thermal budget permits higher loss. |
| Diodes Incorporated DXT53200QE-7 | VCEO = −20 V, IC = −2 A, RCE(sat) = 90 mΩ typ at −2 A; SOT-23, identical pin assignment. | 15 mΩ higher RCE(sat) than PBSS5320T, resulting in ~20% more power loss at full load; slightly lower fT (80 MHz). | Choose for dual-sourcing where minor efficiency trade-off is acceptable and second-source qualification is required. |
Compared with NSS40201MZ4T1G and DXT53200QE-7, PBSS5320T,215 offers the lowest verified RCE(sat) (75 mΩ) and highest hFE (100 min), making it optimal for thermally constrained, high-current PNP switching where base drive simplicity and conduction efficiency are critical.

FAQ
What is the maximum continuous collector current for PBSS5320T,215?
The maximum continuous collector current (IC) is −2 A at Tamb ≤ 25 °C with standard FR4 PCB mounting. Derating applies above 25 °C ambient; at 100 °C ambient, usable IC drops to approximately −0.8 A based on thermal resistance data (Rth(j-a) = 417 K/W) and Tj(max) = 150 °C.
Is PBSS5320T,215 suitable for automotive applications?
No. The PBSS5320T,215 is explicitly designated as non-automotive qualified per Nexperia's revision history (v.4, Jan 2023). It lacks AEC-Q101 qualification, automotive-specific testing, and guaranteed extended temperature operation beyond −65 °C to +150 °C ambient. Automotive alternatives must be selected from Nexperia's −Q qualified portfolio.
How does the SOT23 package affect thermal performance?
The SOT23 package limits thermal dissipation but supports multiple mounting configurations: Rth(j-a) ranges from 417 K/W (standard footprint) down to 104 K/W (pulsed, 6 cm² collector pad). Effective thermal design requires explicit PCB copper area allocation-especially under the collector pad-and adherence to Nexperia's recommended solder land patterns (Fig. 12/13) for optimal heat transfer.
What is the base-emitter saturation voltage at full rated current?
VBE(sat) is −1.2 V at −3 A collector current and −300 mA base current under pulsed conditions (tp ≤ 300 µs, δ ≤ 0.02, Tamb = 25 °C). This value confirms adequate forward bias for full saturation while remaining compatible with 3.3 V or 5 V logic-level drivers when combined with appropriate base resistors.
