Product details

Overview

PBHV9115Z,115 from Nexperia is a PNP high-voltage low-V_CEsat bipolar junction transistor in SOT223 (SC-73) package, rated for −150 V V_CEO, −1 A continuous collector current, and −150 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, HID front lighting, and telecom hook switches where high breakdown voltage and low conduction loss are critical.

For engineers reviewing the PBHV9115Z,115 datasheet, PBHV9115Z,115 pinout, PBHV9115Z,115 application, or PBHV9115Z,115 equivalent, key selection criteria include verified −150 V V_CEO, confirmed 4-pin SOT223 pin mapping with dual collector terminals, measured −60 mV to −120 mV V_CEsat at I_C = −100 mA, thermal resistance R_th(j-sp) = 20 K/W on optimized PCB, and NPN complement PBHV8115Z for push-pull designs.

Technical Context

This PNP BJT operates in active and saturation regions with DC current gain h_FE = 100–220 at V_CE = −10 V, I_C = −50 mA, and drops to h_FE = 10–30 at I_C = −1 A (pulsed). Its low V_CEsat enables reduced power dissipation in high-current switching applications, while the dual-collector SOT223 footprint improves thermal performance over standard 3-lead variants.

Thermal design relies on two mounting configurations: standard FR4 footprint (R_th(j-a) = 175 K/W) and enhanced heatsink pad (6 cm² collector pad, R_th(j-sp) = 20 K/W). Switching times are characterized with t_on = 290 ns, t_off = 730 ns under V_CC = −6 V, I_C = −0.5 A, I_Bon = −0.1 A, I_Boff = 0.1 A conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−150 V - Maximum safe collector-emitter blocking voltage with base open; supports direct drive of 120 V AC rectified rails or HID lamp ignition circuits.
I_C	−1 A - Continuous DC collector current rating; enables driving LED chains up to 1 A without forced air cooling on thermally optimized PCBs.
V_CEsat	−150 mV (typ.) at I_C = −500 mA, I_B = −100 mA - Low saturation voltage reduces conduction loss to <75 mW, critical for thermal management in enclosed lighting modules.
h_FE	100–220 at I_C = −50 mA - High DC current gain allows low-base-drive current designs; maintains h_FE ≥10 even at I_C = −1 A (pulsed), supporting robust switching control.
R_th(j-sp)	20 K/W - Junction-to-solder-point thermal resistance with 6 cm² collector copper pad; enables 1.4 W power dissipation at T_amb ≤25 °C for sustained operation.
f_T	115 MHz - Transition frequency at V_CE = −10 V, I_C = −10 mA; sufficient for PWM dimming frequencies up to 100 kHz with margin.
C_c	10 pF - Collector capacitance at V_CB = −20 V; minimizes switching losses and EMI in fast-switching LED driver topologies.

Pinout & Package

SOT223 (SC-73) medium-power surface-mount package with 4 leads, 2.3 mm pitch, 6.5 mm × 3.5 mm × 1.65 mm body, and integrated heatsink tab connected to pins 2 and 4 (collectors).

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Control terminal for forward-biased PNP operation; requires negative base current relative to emitter to turn on.
2	Collector (C)	Main high-voltage current path terminal; electrically tied to pin 4 for doubled current-carrying capacity and improved thermal conduction.
3	Emitter (E)	Reference terminal for collector current; connected to system ground or positive rail depending on circuit topology (e.g., high-side switch).
4	Collector (C)	Second collector terminal, internally bonded to pin 2; used for enhanced thermal dissipation and parallel current routing in high-reliability layouts.

Key Features

Feature	Design Value
High-voltage blocking	−150 V V_CEO and −200 V V_CB0 enable direct interface with 100–120 V AC line-derived supplies without external snubbers.
Low saturation loss	V_CEsat ≤ −300 mV at I_C = −500 mA ensures <150 mW conduction loss, reducing thermal stress in sealed LED modules.
Dual-collector thermal path	Pins 2 and 4 both connect to collector and heatsink tab, lowering effective R_th(j-sp) to 20 K/W for stable 1.4 W operation.
High-current gain at load	h_FE ≥30 at I_C = −1 A (pulsed) allows simple resistor-based base drive without Darlington stages in telecom hook switch applications.
Fast switching	t_off = 730 ns enables >100 kHz PWM dimming with minimal dead-time overhead in LCD backlight inverters.

Applications

LED Chain Driver

LCD Backlighting

Use Scenario: Driving series-connected white LEDs from 100–120 V DC bus derived from AC rectification in commercial signage.

IC Role / Device Role / Timing Role: High-side PNP switch controlling current through LED string; operates in saturation during ON state with PWM dimming at 1–20 kHz.

Use Value: −150 V V_CEO eliminates need for series MOSFET stacking; −150 mV V_CEsat limits power loss to <75 mW at 500 mA, enabling passive cooling.

Use Scenario: Boost converter output stage in notebook LCD inverters powering CCFL or edge-lit LED arrays.

IC Role / Device Role / Timing Role: Synchronous rectifier or current sink switch in high-frequency (50–100 kHz) resonant converter topologies.

Use Value: 115 MHz f_T and 730 ns t_off support clean switching at 100 kHz; dual-collector layout sustains 1 A peak current without thermal throttling.

HID Front Lighting

Telecom Hook Switch

Use Scenario: Ignition and run-mode current control in automotive or industrial HID headlamp ballasts operating from 12–24 V battery with 100+ V ignition pulses.

IC Role / Device Role / Timing Role: Main switching transistor handling both high-voltage ignition transients and steady-state lamp current up to 1 A.

Use Value: −200 V V_CB0 withstands ignition spikes; −150 V V_CEO supports direct connection to lamp anode; R_th(j-sp) = 20 K/W prevents thermal runaway during 30 s warm-up phase.

Use Scenario: Loop disconnect and polarity reversal in wired telephone line interface circuits (e.g., SLIC auxiliary switch).

IC Role / Device Role / Timing Role: High-voltage PNP switch isolating subscriber line during off-hook detection and battery feed reversal.

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
PHPT610030XK	−100 V V_CEO, −3 A I_C, SOT223-3 (3-pin), V_CEsat = −220 mV @ I_C = −1.5 A	Lower voltage rating limits use to ≤80 V systems; higher current capability suits high-power LED drivers but lacks dual-collector thermal path.	Select when higher I_C is prioritized over voltage margin and thermal optimization is handled via external heatsinking.
MBT3906DW1T1G	−40 V V_CEO, −200 mA I_C, SOT363 (6-pin), h_FE = 100–300, V_CEsat = −400 mV @ I_C = −50 mA	Not suitable for >−40 V applications; intended for low-voltage logic-level switching, not HV power control.	Reject for any application requiring >−60 V blocking; only consider for signal-level PNP functions in non-HV subsystems.

Compared with PHPT610030XK, PBHV9115Z,115 trades 2 A current headroom for 50 V higher blocking and superior thermal resistance via dual-collector SOT223; versus MBT3906DW1T1G, it delivers 3.75× higher voltage rating and 5× higher current, making it the sole viable option for 100–120 V LED/HID/telecom switching.

FAQ

What is the maximum allowable continuous collector current for PBHV9115Z,115?

The absolute maximum continuous collector current (I_C) is −1 A at T_amb ≤25 °C with proper PCB thermal management. Derating applies above 25 °C per Figure 1: at 75 °C ambient, maximum I_C drops to ~0.6 A for standard FR4 layout, or ~0.9 A with 6 cm² collector pad. Exceeding these limits risks thermal runaway due to R_th(j-a) = 175 K/W in free air.

Can PBHV9115Z,115 be used as a direct replacement for PBHV8115Z?

No - PBHV8115Z is the NPN complement, not a functional replacement. They share identical voltage/current ratings (150 V, 1 A) and SOT223-4 packaging but opposite polarity: PBHV9115Z is PNP (base-driven negative current), PBHV8115Z is NPN (base-driven positive current). They are paired in complementary circuits like push-pull drivers, not substituted one-for-one.

What is the significance of the dual-collector configuration (pins 2 and 4)?

Pins 2 and 4 are internally shorted to the same collector node and the exposed heatsink tab. This doubles the solder joint area and current-carrying cross-section, reducing effective thermal resistance from junction to solder point to 20 K/W (vs. ~89 K/W to ambient) when mounted on a 6 cm² copper pad. It also lowers R_CEsat by distributing current across two parallel paths.

Does PBHV9115Z,115 meet automotive qualification standards?

No - the datasheet revision v.4 (20241008) explicitly states "Product(s) changed to non-automotive qualification" and directs users to Nexperia's website for automotive-qualified (−Q) alternatives. PBHV9115Z,115 is rated for industrial temperature range (−55 °C to 150 °C) but lacks AEC-Q101 stress testing, PPAP documentation, or automotive-specific failure mode analysis.
