Product details

Overview

CPH6102-TL-E from onsemi is a PNP bipolar junction transistor (BJT) rated for −50 V V_CEO, −1 A continuous collector current, and low −180 mV typical V_CE(sat) at I_C = −500 mA / I_B = −50 mA. It features high-speed switching (t_on = 40 ns, t_f = 30 ns), f_T = 150 MHz, and operates in ultrasmall CPH6 (SOT-26/SC-74) package for space-constrained DC-DC converters and motor drivers.

For engineers reviewing the CPH6102-TL-E datasheet, pinout, applications, or equivalent options, key selection criteria include verified −50 V breakdown rating, confirmed four-collector-terminal configuration, measured −180 mV V_CE(sat) under specified bias, and JEDEC-qualified SOT-26 mechanical compatibility for automated assembly.

Technical Context

This PNP BJT employs onsemi's FBET and MBIT processes to achieve high current gain (h_FE = 200–560 at I_C = −100 mA) and stable performance across temperature. Its four parallel collector terminals reduce effective on-resistance and improve thermal dissipation in high-current switching paths.

The device supports fast switching with 40 ns turn-on and 30 ns fall time under defined test conditions (V_CC = −25 V, R_B = 50 Ω), while maintaining low output capacitance (C_ob = 12 pF at V_CB = −10 V) to minimize switching losses in PWM-driven loads like relay coils and lamp drivers.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−50 V - Maximum safe collector-emitter voltage before avalanche breakdown; enables use in 24 V and 48 V industrial bus switching
I_C (cont.)	−1.0 A - Continuous DC collector current handling; supports ≥10 W load drive with proper heatsinking
V_CE(sat)	−180 mV (typ.) at I_C = −500 mA / I_B = −50 mA - Low saturation voltage reduces conduction loss and self-heating in high-duty-cycle applications
f_T	150 MHz - Gain-bandwidth product confirms suitability for >1 MHz switching frequencies in synchronous rectifiers or gate drivers
t_f	30 ns - Measured fall time under standard test circuit; enables clean edge transitions in strobe and pulse-width modulated lighting
P_C	1.3 W (on ceramic substrate) - Power dissipation capability allows operation up to ~100°C ambient without forced cooling in compact layouts
C_ob	12 pF at V_CB = −10 V - Low output capacitance minimizes Miller effect and improves switching efficiency in high-frequency inverters

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP bipolar transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MBT3906DW1T1G	Double-die SOT-363 package; V_CEO = −40 V, I_C = −200 mA per device, V_CE(sat) = −400 mV (typ.)	Lower voltage/current rating; suited for signal-level logic translation, not power switching	Select only for low-power bias networks where footprint matches and −40 V suffices
PN2907A	TO-92 package; V_CEO = −60 V, I_C = −600 mA, V_CE(sat) = −1.6 V (max) at I_C = −500 mA	Through-hole mounting; higher V_CE(sat) increases conduction loss; unsuitable for high-frequency PWM	Choose only for legacy through-hole designs requiring −60 V rating and no surface-mount constraints

Compared with MBT3906DW1T1G and PN2907A, CPH6102-TL-E delivers superior power-handling (−1 A, −50 V), lower saturation voltage (−180 mV), and SMT-compatible CPH6 packaging-making it the only option among the three qualified for compact, high-efficiency DC-DC and motor drive applications.

FAQ

What is the maximum continuous collector current rating for CPH6102-TL-E?

The CPH6102-TL-E is rated for −1.0 A continuous collector current (I_C) at T_a = 25°C when mounted on a ceramic substrate (600 mm² × 0.8 mm). Derating applies above 25°C ambient, with full rating maintained up to ~75°C ambient under typical PCB thermal conditions. This rating relies on all four collector terminals (pins 1, 2, 5, 6) being properly connected in parallel on the PCB layout.

Does CPH6102-TL-E support high-frequency switching applications?

Yes, CPH6102-TL-E supports high-frequency switching with a measured gain-bandwidth product (f_T) of 150 MHz and fast switching times (t_on = 40 ns, t_f = 30 ns) under standardized test conditions. These parameters confirm suitability for PWM-based applications up to several megahertz, including LED strobes and synchronous rectification in DC-DC converters.

What package type is used for CPH6102-TL-E, and is it compatible with standard SOT-26 footprints?

CPH6102-TL-E uses the CPH6 package, which is mechanically identical to JEDEC SOT-26 and JEITA SC-74. Its 2.9 mm × 1.6 mm body, 0.6 mm lead pitch, and 6-pin configuration are fully compatible with standard SOT-26 land patterns and reflow profiles, enabling drop-in use in existing SOT-26 assembly lines without tooling changes.

What is the typical collector-emitter saturation voltage (V_CE(sat)) of CPH6102-TL-E, and under what conditions is it specified?

The typical V_CE(sat) of CPH6102-TL-E is −180 mV, measured at I_C = −500 mA and I_B = −50 mA (I_C/I_B = 10) with T_a = 25°C. This low saturation voltage is enabled by onsemi's FBET process and the four-collector terminal design, directly reducing conduction loss in power switching applications.

Can CPH6102-TL-E replace older PNP transistors like the 2N3906 in high-current applications?

No-CPH6102-TL-E is not a direct replacement for 2N3906 due to fundamental differences: 2N3906 is rated for −200 mA and −40 V, while CPH6102-TL-E delivers −1 A and −50 V with four collector pins. Substituting CPH6102-TL-E into a 2N3906 footprint would cause solder joint stress and incorrect pin mapping. Use only in designs specifically laid out for CPH6 (SOT-26) with verified collector terminal routing.
