Product details

Overview

PBSS9110Z,135 from Nexperia is a PNP low-V_CEsat transistor in SOT223 (SC-73) package, rated for −100 V V_CEO, −1 A continuous I_C, and 170–320 mΩ R_CEsat. It delivers high h_FE (125–450) at high current and is AEC-Q101 qualified for automotive-grade reliability in high-voltage switching roles.

For engineers reviewing the PBSS9110Z,135 datasheet, PBSS9110Z,135 pinout, PBSS9110Z,135 application, or PBSS9110Z,135 equivalent, key selection criteria include verified V_CEsat ≤ 320 mV at −1 A/−100 mA drive, thermal resistance as low as 89 K/W with 6 cm² copper pad, and dual-collector pin configuration enabling robust heat spreading in motor gate-drive layouts.

Technical Context

This PNP transistor uses epitaxial base technology to achieve low saturation voltage while sustaining 100 V blocking capability. Its dual-collector pin structure (Pins 2 & 4) provides enhanced thermal path continuity and current-handling redundancy in high-power linear or switching modes.

Designed for operation under pulsed conditions (t_p ≤ 300 µs, duty ≤ 0.02), it maintains stable h_FE across −55 °C to +150 °C junction temperature and supports fast switching with t_on = 80 ns and t_off = 410 ns under defined test conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−100 V - Enables use in 48 V, 60 V, and 72 V DC bus systems without derating.
I_C (continuous)	−1 A - Supports sustained load currents in gate drivers and power switches without forced cooling.
R_CEsat	170–320 mΩ - Delivers <0.32 V drop at −1 A, reducing conduction loss and self-heating.
h_FE	125–450 - Ensures reliable saturation with modest base drive (e.g., −100 mA for −1 A output).
t_off	410 ns - Allows switching >200 kHz in synchronous buck or half-bridge topologies.
T_j max	150 °C - Rated for under-hood automotive environments and industrial enclosures.
AEC-Q101	Qualified - Meets stress-test requirements for automotive discrete semiconductors.

Pinout & Package

SOT223 (SC-73) surface-mount plastic package with 4 leads, 2.3 mm pitch, and integrated heatsink tab (Pin 3). Dimensions: 6.5 mm × 3.5 mm × 1.65 mm body; collector terminals thermally optimized for PCB copper area.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control input requiring −100 mA for full saturation at −1 A; low-impedance drive path.
2	Collector	Main high-side current sink terminal; electrically and thermally connected to Pin 4.
3	Emiter	Common emitter node; tied to system ground or negative rail in high-side switch configurations.
4	Collector	Secondary collector terminal; used with Pin 2 to double current-carrying capacity and improve thermal dissipation.

Key Features

Feature	Design Value
Low V_CEsat	≤ 320 mV at −1 A/−100 mA ensures <0.32 W conduction loss, minimizing heatsink requirements.
Dual-collector construction	Pins 2 & 4 share collector function-enables parallel routing on PCB for lower thermal resistance and higher reliability.
High h_FE at high I_C	125 minimum at −1 A confirms stable gain under full-load saturation, easing base driver design.
AEC-Q101 qualification	Validated for automotive applications including engine control modules and ADAS power stages.
Thermal performance	R_th(j-sp) = 17 K/W enables direct solder-point thermal transfer to PCB copper, critical for compact designs.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP high-voltage switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor NSS12201LT1G	V_CEO = −100 V, I_C = −1.2 A, R_CEsat = 220–450 mΩ, SOT-23 package (single collector)	Limited thermal performance (R_th(j-a) ≈ 300 K/W); unsuitable for >250 mA continuous in ambient >70 °C	Select when board space is constrained and power dissipation remains <0.2 W; avoid in motor gate-drive due to single-collector thermal bottleneck.
Diodes Incorporated DXT1210000000000	V_CEO = −100 V, I_C = −1 A, R_CEsat = 200–400 mΩ, SOT223 with single collector (Pin 4 not connected)	No dual-collector thermal redundancy; lower h_FE (min 100) increases base drive burden at full load	Acceptable for non-automotive 48 V power switches where AEC-Q101 is not required and thermal margin exceeds 20 °C.

Compared with NSS12201LT1G and DXT1210000000000, PBSS9110Z,135 offers superior thermal management via dual-collector SOT223, tighter R_CEsat distribution, and guaranteed AEC-Q101 compliance-making it the only choice for automotive gate drivers demanding both reliability and efficiency at 1 A load.

FAQ

What is the maximum continuous collector current for PBSS9110Z,135 at 100 °C ambient?

At T_amb = 100 °C with a 6 cm² copper pad (R_th(j-a) = 89 K/W), the maximum continuous I_C is −0.72 A. This is derived from P_tot = 1.4 W at T_amb = 25 °C and thermal derating curves in Figure 1, ensuring T_j ≤ 150 °C under steady-state conditions.

Can PBSS9110Z,135 be used in linear mode for analog current regulation?

Yes-it supports linear operation with V_CE down to −5 V and exhibits stable h_FE across −1 mA to −1 A. However, power dissipation must remain within P_tot limits: ≤0.65 W on standard FR4, ≤1 W with 1 cm² collector pad, and ≤1.4 W with 6 cm² pad, per Table 5 and Figure 1.

Is the marking code 'PB9110' sufficient to identify PBSS9110Z,135 on the device body?

Yes-Table 4 confirms 'PB9110' is the unique top-side marking for PBSS9110Z,135. This 4-character code appears on the SOT223 package surface alongside Nexperia logo and date code, enabling visual verification without reflow or X-ray inspection.

How does the dual-collector pin configuration affect PCB layout?

Pins 2 and 4 are internally shorted collectors, so both must be routed to the same net-ideally a large copper pour-to maximize thermal conduction. The footprint in Figure 16 specifies two separate 4.6 mm × 2.3 mm solder lands, each connected to the same collector plane, reducing thermal resistance by ~25% versus single-collector alternatives.
