Product details

Overview

PBHV9115TLH from Nexperia is a PNP high-voltage low V_CEsat transistor in SOT23 package, rated for −150 V V_CEO, −1 A continuous collector current, and −300 mV typical V_CEsat at I_C = −500 mA / I_B = −100 mA. It serves as a high-efficiency switching element in LED chain drivers and SMPS primary-side control circuits.

For engineers reviewing the PBHV9115TLH datasheet, PBHV9115TLH pinout, PBHV9115TLH application, or PBHV9115TLH equivalent, key selection criteria include its −150 V blocking capability, low saturation voltage under high-current switching, thermal resistance of 417 K/W (junction-to-ambient), and compatibility with standard SOT23 reflow footprints.

Technical Context

This PNP bipolar junction transistor operates with open-base V_CEO = −150 V and supports peak pulsed collector current up to −2 A. Its DC current gain (h_FE) ranges from 10 to 300 depending on operating point, with minimum h_FE = 10 confirmed at I_C = −1 A (pulsed).

Switching performance includes t_on = 295 ns and t_off = 730 ns under V_CC = −6 V, I_C = −0.5 A test conditions. Thermal design must account for R_th(j-a) = 417 K/W on FR4 PCB and R_th(j-sp) = 70 K/W to solder point.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−150 V - maximum safe collector-emitter voltage with base open; enables use in 100–120 V AC-derived rails
I_C	−1 A - continuous DC collector current rating; defines steady-state power stage capacity
V_CEsat	−300 mV (typ.) at I_C = −500 mA / I_B = −100 mA - low conduction loss improves efficiency in high-side switch configurations
h_FE	10 (min.) at I_C = −1 A - ensures sufficient current gain for reliable saturation with practical base drive
f_T	55 MHz - usable for medium-speed switching up to ~1–2 MHz with margin
R_th(j-a)	417 K/W - requires thermal-aware PCB layout (e.g., copper pour) for >150 mW sustained dissipation
t_off	730 ns - determines minimum off-time in PWM-controlled LED or SMPS applications

Pinout & Package

Package: SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch), optimized for automated assembly and space-constrained designs.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Control input; requires negative current injection to turn on PNP device; compatible with standard logic-level or resistor-biased drive
2	Emitter (E)	High-side reference node; connects to positive rail in high-side switch topology; carries full load current
3	Collector (C)	Switched output node; connects to load (e.g., LED anode or SMPS transformer primary); reverse polarity relative to NPN

Key Features

Feature	Design Value
High-voltage blocking	−150 V V_CEO enables direct interface with rectified 100–120 VAC inputs without cascaded stages
Low V_CEsat	−300 mV typical at 500 mA reduces conduction loss by >50% vs. standard PNP transistors in same package
Robust pulsed current	−2 A I_CM supports short-duration surge handling in LED strobing or SMPS startup
SOT23 footprint compatibility	Standard JEDEC SOT23 outline allows drop-in replacement in existing layouts designed for similar discrete transistors
Thermal performance	R_th(j-sp) = 70 K/W enables localized heat extraction via solder pad, critical for sustained 150–200 mW operation

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
PBHVA115Z	Same SOT23 package; −150 V V_CEO; −1.5 A I_C; −250 mV V_CEsat (typ.) at I_C = −500 mA	Higher current rating and lower V_CEsat suit higher-power LED drivers	Select when ≥1.2 A continuous current or <−250 mV saturation voltage is required
BCX69-16	SOT89 package; −100 V V_CEO; −1 A I_C; −500 mV V_CEsat (typ.) at I_C = −500 mA	Larger thermal mass but lower voltage rating; not suitable for 120 VAC-derived rails	Choose only for ≤100 V systems where board space allows SOT89 and higher thermal dissipation is needed

Compared with PBHV9115TLH, PBHVA115Z offers improved current and saturation performance in identical footprint, while BCX69-16 trades voltage capability for thermal robustness in a larger package-neither is pin-compatible, but both serve overlapping high-voltage PNP switching roles.

FAQ

What is the maximum collector-emitter voltage rating for PBHV9115TLH?

The PBHV9115TLH has a maximum collector-emitter voltage (V_CEO) rating of −150 V with the base open, as specified in the Absolute Maximum Ratings table. This rating is validated per IEC 60134 and applies to continuous DC operation at T_amb ≤ 25 °C. The device also supports −200 V peak collector-emitter voltage (V_CESM) under transient conditions with V_BE = 0 V.

Does PBHV9115TLH have automotive qualification?

No, PBHV9115TLH is not automotive-qualified. According to the revision history in the official datasheet (v.3, 9 October 2024), this part was explicitly changed to non-automotive qualification status. Nexperia provides separate −Q qualified alternatives for automotive applications, and PBHV9115TLH must not be used in safety-critical or life-support systems.

What is the typical VCEsat of PBHV9115TLH at full rated current?

The typical V_CEsat of PBHV9115TLH is −300 mV at I_C = −500 mA and I_B = −100 mA (pulsed, t_p ≤ 300 µs). At full rated continuous current (I_C = −1 A), the datasheet specifies a minimum h_FE of 10 but does not list a guaranteed V_CEsat value; design margins should assume ≤−500 mV based on Fig. 7 and Fig. 8 curves at I_C/I_B = 5–20.

Can PBHV9115TLH replace an NPN transistor in the same circuit?

No, PBHV9115TLH cannot directly replace an NPN transistor due to opposite polarity and complementary biasing requirements. As a PNP device, it conducts when the base is driven negative relative to the emitter, whereas NPNs require positive base drive. The NPN complement explicitly listed in the datasheet is PBHV8115TLH-not a drop-in substitute but a matched counterpart for push-pull or complementary designs.

What is the thermal resistance from junction to ambient for PBHV9115TLH on standard FR4?

The thermal resistance from junction to ambient (R_th(j-a)) for PBHV9115TLH is 417 K/W when mounted on a standard FR4 PCB with single-sided copper, tin-plated, and using the recommended footprint. This value assumes free-air convection and is critical for calculating maximum allowable power dissipation at elevated ambient temperatures using the derating curve in Figure 1.
