Product details

Overview

PBSS5230T/ZLR from Nexperia is a PNP low V_CEsat transistor in SOT23 package, rated for −30 V V_CEO, −2 A continuous collector current, and 160–220 mΩ R_CEsat at −500 mA/−50 mA drive; used as high-efficiency switch in DC-DC converters and LED backlight drivers.

For engineers reviewing the PBSS5230T/ZLR datasheet, PBSS5230T/ZLR pinout, PBSS5230T/ZLR application, or PBSS5230T/ZLR equivalent, this page delivers verified electrical parameters, thermal behavior under FR4 mounting, real-world saturation voltage curves, and validated alternatives for low-voltage PNP switching designs.

Technical Context

This PNP bipolar transistor operates with base-emitter turn-on voltage of −0.75 V at −100 mA and delivers DC current gain (h_FE) of 100–180 at −2 A/−200 mA drive. Its low saturation resistance enables stable switching below 240 mV V_CEsat at full rated current.

Designed for pulsed operation (t_p ≤ 300 µs, duty δ ≤ 0.02), it supports peak collector current up to −3 A and maintains junction temperature ≤ 150 °C. Thermal resistance is 260 K/W when mounted on FR4 with 1 cm² collector pad.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−30 V - Maximum safe collector-emitter voltage with open base; defines off-state blocking capability in supply-line switching.
I_C	−2 A - Continuous DC collector current rating; sets maximum steady-state load current in battery charger or relay driver.
V_CEsat	−240 to −350 mV at −2 A/−200 mA - Confirmed saturation voltage range; directly determines conduction loss and heat generation in high-duty-cycle apps.
R_CEsat	160–220 mΩ at −500 mA/−50 mA - Measured saturation resistance; enables precise I²R loss calculation in low-voltage DC-DC stages.
h_FE	100–180 at −2 A - Verified DC current gain; ensures reliable base drive sizing for digital logic-compatible control inputs.
f_T	100–200 MHz - Transition frequency at −10 V V_CE, −100 mA I_C; confirms suitability for medium-speed switching up to ~10 MHz.
P_tot	480 mW at T_amb ≤ 25 °C with optimized PCB pad - Total power dissipation limit under standard FR4 mounting; constrains thermal design margin.

Pinout & Package

SOT23 plastic surface-mounted package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pitch); thermally enhanced for FR4 PCBs with dedicated collector pad.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Control input node requiring −50 mA to −200 mA drive for full saturation; referenced to emitter for PNP biasing.
2	Emitter (E)	Common reference terminal tied to positive rail in high-side switch configuration; carries full load current.
3	Collector (C)	Switched output node connected to load; electrically isolated from PCB ground; requires ≥1 cm² copper for thermal management.

Key Features

Feature	Design Value
Low V_CEsat	As low as −240 mV at −2 A enables <100 mW conduction loss in 3.3 V systems, reducing heatsink need.
High I_C capability	−2 A continuous rating supports direct driving of relays, buzzers, and multi-LED strings without external buffering.
Optimized for pulsed operation	Validated at t_p ≤ 300 µs and δ ≤ 0.02 - matches typical PWM timing in LCD backlight dimming and motor commutation.
Thermally robust SOT23	R_th(j-a) = 260 K/W with 1 cm² collector pad - achieves 150 °C max junction temp at 480 mW dissipation on standard FR4.

Applications

DC-to-DC Conversion

Supply Line Switching

Use Scenario: Step-down converter in portable medical devices requiring <50 mV dropout and minimal thermal rise.

IC Role / Device Role / Timing Role: High-side synchronous rectifier switch operating at 500 kHz PWM with 20% duty cycle.

Use Value: 160 mΩ R_CEsat limits I²R loss to 40 mW at 500 mA, enabling fanless enclosure design.

Use Scenario: Power sequencing in industrial PLC I/O modules where 24 V supply must be gated before microcontroller boot.

IC Role / Device Role / Timing Role: PNP load switch controlled by GPIO with active-low enable signal.

Use Value: −30 V V_CEO and −2 A rating allow direct 24 V/1.5 A rail control without derating or series FET.

Use Scenario: Charge path selector in dual-battery handheld test equipment switching between Li-ion packs.

IC Role / Device Role / Timing Role: Reverse-polarity protected high-side switch isolating battery terminals during charging cycles.

Use Value: −5 V V_EBO rating prevents base-emitter breakdown during hot-swap events; −300 mA I_B max supports logic-level drive.

Use Scenario: Constant-current LED string driver in automotive infotainment display with 3.3 V logic supply.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor NSS20201MR6T1G	V_CEO = −20 V, I_C = −2 A, V_CEsat = −220 mV @ −1 A - lower voltage rating but tighter V_CEsat tolerance.	Not suitable for 24 V supply switching due to −20 V V_CEO; acceptable only in ≤15 V DC-DC stages.	Select when operating voltage ≤15 V and tighter V_CEsat consistency is prioritized over voltage headroom.
Diodes Incorporated DXT5230PZ-7	V_CEO = −30 V, I_C = −2 A, V_CEsat = −300 mV @ −2 A - higher V_CEsat and 3× higher R_th(j-a) (800 K/W).	Requires larger PCB copper area to maintain T_j < 150 °C; less efficient in thermally constrained spaces.	Choose only if PBSS5230T/ZLR is unavailable and thermal budget allows 2.5× higher junction rise per watt.

Compared with NSS20201MR6T1G and DXT5230PZ-7, PBSS5230T/ZLR uniquely balances −30 V blocking, −240 mV min V_CEsat, and 260 K/W thermal resistance - making it optimal for space-constrained 24 V industrial switches where both voltage margin and thermal performance are critical.

FAQ

What is the maximum allowable base current for PBSS5230T/ZLR?

The absolute maximum base current is −300 mA, as specified in Table 5 (Limiting Values). This rating applies under pulsed conditions (t_p ≤ 1 ms) and ensures safe operation without bond wire fusing. For continuous DC operation, base current should be limited to ≤−200 mA to maintain long-term reliability and avoid thermal runaway.

Can PBSS5230T/ZLR replace an NPN transistor in a circuit?

No - PBSS5230T/ZLR is a PNP transistor with inverted polarity: emitter connects to higher potential, collector to load, and base driven low to turn on. Direct replacement of an NPN requires circuit reconfiguration including inversion of control signals and power rail referencing. Its NPN complement is PBSS4230T.

Is PBSS5230T/ZLR qualified for automotive applications?

No - the revision history explicitly states that PBSS5230T/ZLR was changed to non-automotive qualification in v.4 (20250930). It lacks AEC-Q101 stress testing and automotive-specific failure reporting. For automotive use, Nexperia offers separate −Q qualified variants such as PBSS5230T,115.

How does PCB layout affect PBSS5230T/ZLR thermal performance?

Thermal resistance drops from 417 K/W (standard footprint) to 260 K/W when a 1 cm² copper pad is added under the collector terminal, per Table 6. Without this pad, junction temperature exceeds 150 °C at just 290 mW dissipation. Solder mask-defined thermal pads and internal plane connections further reduce R_th in multilayer boards.
