Product details

Overview

PBSS9110X,135 from Nexperia is a PNP low V_CEsat Breakthrough In Small Signal (BISS) transistor in SOT89 package, designed for high-efficiency switching in automotive 42 V power systems, telecom infrastructure, and industrial DC-to-DC conversion. It delivers −100 V V_CEO, −1 A continuous collector current, 170–320 mΩ R_CEsat at −1 A/−100 mA drive, −320 mV V_CEsat, and 100 MHz f_T.

For engineers reviewing the PBSS9110X,135 datasheet, PBSS9110X,135 pinout, PBSS9110X,135 application, or PBSS9110X,135 equivalent, key selection criteria include low saturation voltage under high-current drive, thermal performance on FR4 PCBs with collector pad, and compatibility with inductive load switching in 12–42 V systems.

Technical Context

This BISS transistor uses a proprietary PNP epitaxial structure enabling significantly lower V_CEsat than standard bipolar transistors at comparable I_C/I_B ratios. Its high h_FE (125–450 at −1 A) supports efficient base drive with minimal current loss.

It operates across −65 °C to +150 °C junction temperature, with thermal resistance as low as 63 K/W when mounted on ceramic PCB (Al₂O₃). Switching performance includes 80 ns t_on, 410 ns t_off, and 290 ns storage time under −0.5 A load conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−100 V - Withstands 42 V automotive system transients with robust margin
I_C (DC)	−1 A - Supports continuous switching of lamps, relays, and small motors
R_CEsat	170–320 mΩ at −1 A/−100 mA - Enables <0.32 W conduction loss at full rated current
f_T	100 MHz - Suitable for high-frequency PWM control up to ~10 MHz practical switching
h_FE	125–450 at −1 A - Reduces required base drive current and driver stage complexity
t_off	410 ns - Limits switching losses during turn-off in DC-DC converters
P_tot (FR4, 6 cm² pad)	1.4 W - Allows >1 W continuous dissipation without heatsink in compact layouts

Pinout & Package

SOT89 (SC-62/TO-243) surface-mount plastic package with exposed collector pad for enhanced thermal transfer. Standard footprint fits automated reflow assembly; recommended pad layout per Figure 17 (Nexperia doc PBSS9110X_2).

Pin/Terminal	Circuit Role	Design Meaning
1	Emitter	Current return path; connects to system ground or low-side reference in high-side switch configurations
2	Collector	Main power output terminal; thermally coupled to PCB copper pad for heat dissipation
3	Base	Control input; requires −100 mA drive for full saturation at −1 A load

Key Features

Feature	Design Value
Low V_CEsat	−320 mV at −1 A/−100 mA enables <0.32 W conduction loss, reducing thermal stress in space-constrained designs
High I_CM	−3 A peak current supports surge handling for relay coil energization and motor startup
High h_FE	Min 125 at −1 A reduces base drive power and simplifies gate driver interface
Thermal robustness	R_th(j-a) = 63 K/W on ceramic PCB allows operation up to 125 °C ambient without derating
Fast switching	410 ns t_off and 120 ns t_f minimize dead-time losses in synchronous buck topologies

Applications

Automotive Lighting Control

Industrial Relay Driver

Use Scenario: Driving 12–42 V LED headlamps and interior lighting in passenger vehicles with PWM dimming.

IC Role / Device Role / Timing Role: High-side PNP switch controlling current flow from battery rail to LED string.

Use Value: Low R_CEsat minimizes voltage drop and self-heating, enabling stable brightness over wide temperature range (−40 °C to +125 °C).

Use Scenario: Activating 24 V industrial control relays in PLC I/O modules.

IC Role / Device Role / Timing Role: Inductive load switch with flyback protection interface.

Use Value: −3 A I_CM safely handles relay coil inrush; fast t_off prevents contact chatter during rapid cycling.

Telecom DC-DC Converter

Consumer Appliance Motor Driver

Use Scenario: Synchronous rectifier or main switch in isolated 48 V input telecom power supplies.

IC Role / Device Role / Timing Role: Primary-side PNP switch in forward or active-clamp topology.

Use Scenario: Driving small brushed DC motors in smart home appliances (e.g., HVAC dampers, coffee grinders).

IC Role / Device Role / Timing Role: Low-voltage H-bridge half-bridge element or unidirectional motor enable switch.

Use Value: −1 A continuous rating and −100 V V_CEO provide margin against back-EMF spikes during abrupt stop/start cycles.

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
PN2907A	V_CEO = −60 V, V_CEsat ≈ −1.6 V at −500 mA - 5× higher saturation voltage	Not suitable for 42 V automotive or high-efficiency DC-DC; limited to ≤24 V logic-level loads	Select only if cost sensitivity outweighs efficiency and thermal requirements
MMBT6517	V_CEO = −120 V, but R_CEsat = 500–800 mΩ at −1 A - higher conduction loss	Acceptable for telecom infrastructure where voltage margin is critical but thermal budget is宽松	Prefer when absolute breakdown rating >100 V is mandatory and board area allows larger thermal pad

Compared with PN2907A and MMBT6517, PBSS9110X,135 delivers superior efficiency in 36–42 V systems due to its 170–320 mΩ R_CEsat, enabling smaller thermal pads and higher power density-critical for automotive and telecom space constraints.

FAQ

What is the maximum safe operating junction temperature for PBSS9110X,135?

The absolute maximum junction temperature is 150 °C per the datasheet limiting values. Operation above this threshold risks permanent degradation of h_FE and increased leakage. Derating is required above 25 °C ambient-e.g., P_tot drops to 1.4 W at 60 °C ambient on FR4 with 6 cm² collector pad.

Can PBSS9110X,135 be used as a direct replacement for a standard PNP bipolar transistor like BC807?

No-it is not a drop-in replacement. PBSS9110X has higher gain (h_FE ≥125 at −1 A vs. BC807's ~100 at −100 mA), lower V_CEsat (−320 mV vs. −900 mV), and different thermal behavior. Base resistor values must be recalculated, and PCB thermal relief redesigned to accommodate its collector-pad mounting requirement.

Does PBSS9110X,135 require external flyback protection when driving inductive loads?

Yes-while it withstands −100 V V_CEO, inductive kickback can exceed this during rapid turn-off. A reverse-biased diode (e.g., BAS21) across the load is mandatory for relay, buzzer, or motor applications to clamp voltage spikes and prevent junction breakdown.

What is the meaning of the '135' suffix in PBSS9110X,135?

The '135' denotes the tape-and-reel packing variant: 4000 units per reel, 8 mm tape width, 12 mm pocket pitch. It corresponds to the 12NC ordering code ending in -135 and is functionally identical to PBSS9110X,115 (1000-unit reel); only packaging differs.
