Product details
Overview
PBSS5320X,135 from Nexperia is a PNP low VCEsat (BISS) transistor in SOT89 package, designed for high-efficiency switching in low-voltage power paths. It delivers −20 V VCEO, −3 A continuous IC, 90–105 mΩ RCEsat at −3 A/−300 mA drive, and AEC-Q101 qualification-enabling robust operation in automotive-grade DC/DC converters and battery charger control circuits.
For engineers reviewing the PBSS5320X,135 datasheet, PBSS5320X,135 pinout, PBSS5320X,135 application, or PBSS5320X,135 equivalent, key selection criteria include verified low saturation resistance under pulsed conditions, thermal performance on FR4 vs. ceramic PCBs, junction temperature limits up to 150 °C, and compatibility with standard SOT89 reflow footprints per Fig. 13.
Technical Context
This PNP BISS transistor uses a bipolar structure optimized for low-saturation operation, with base-emitter turn-on voltage of −1.1 V at −1 A and VBEsat ≤ −1.2 V at −3 A/−300 mA. Its hFE ranges from 100 (at −3 A) to 220 (at −0.1 A), supporting stable current gain across load conditions.
Thermal design is enabled by multiple Rth(j-a) values: 225 K/W (standard FR4), 90 K/W (6 cm² collector pad), and 80 K/W (ceramic PCB). Transient thermal impedance curves (Figs. 2–3) confirm suitability for pulsed inductive loads like relays and buzzers with duty cycles down to 1%.
Key Specifications

| VCEO | −20 V - Maximum safe collector-emitter blocking voltage in open-base configuration. |
| IC | −3 A - Continuous DC collector current rating on 7 cm² ceramic PCB per IEC 60134. |
| RCEsat | 90–105 mΩ - Verified on-resistance at −3 A/−300 mA drive, enabling <0.3 V saturation drop. |
| hFE | 100–220 - DC current gain range across −0.1 A to −3 A, supporting predictable base drive sizing. |
| Tj max | 150 °C - Absolute maximum junction temperature, defining thermal derating envelope. |

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 |
|---|---|---|---|
| ON Semiconductor NSS40501MR6T1G | −20 V VCEO, −4 A IC, but higher RCEsat (150 mΩ typical) and no AEC-Q101 rating. | Acceptable for industrial DC/DC but not automotive due to missing qualification. | Select when higher peak current is prioritized over thermal efficiency and automotive compliance. |
| Diodes Incorporated DXT53200Q-7 | −20 V VCEO, −3 A IC, RCEsat = 110–130 mΩ, AEC-Q101 qualified, same SOT89 package. | Compatible footprint and qualification, but 15–25% higher saturation resistance increases power loss. | Choose if Nexperia supply constraints exist and marginal efficiency loss is acceptable. |
Compared with PBSS5320X,135, NSS40501MR6T1G trades automotive qualification for higher peak current, while DXT53200Q-7 matches qualification and package but sacrifices 15–25% conduction efficiency-making PBSS5320X,135 optimal where thermal performance and automotive compliance are jointly critical.

FAQ
What is the maximum allowable base current for continuous operation?
The absolute maximum base current is −500 mA per Table 5. However, for reliable continuous operation at −3 A collector current, the datasheet specifies −300 mA base drive (IC/IB = 10) to ensure full saturation without excessive base power dissipation or thermal stress on the bond wires.
Can PBSS5320X,135 be used in parallel for higher current handling?
No-this PNP BISS transistor lacks inherent current-sharing characteristics due to negative temperature coefficient of VCEsat. Parallel operation risks thermal runaway; Nexperia does not recommend or characterize it for such use. For higher current, select a single higher-rated device like PBSS5350X.
Is the SOT89 footprint compatible with wave soldering?
Yes-the datasheet provides dedicated wave soldering land pattern (Fig. 14) with 7.6 mm length and 2.4 mm width, plus solder resist openings sized for capillary flow. Thermal pad must remain unmasked to ensure mechanical and thermal integrity during wave process.
How does RCEsat change with temperature and current?
RCEsat increases with junction temperature: Fig. 10 shows ~15% rise from 25 °C to 100 °C at IC/IB = 20. At fixed temperature, it decreases with higher IB ratio-e.g., 90 mΩ at IC/IB = 10 drops to ~75 mΩ at IC/IB = 100-confirming strong gate-drive sensitivity in BISS architecture.
