Product details

Overview

CPH3107-TL-E from onsemi is a PNP bipolar junction transistor (BJT) rated for −15 V V_CEO, −6 A I_C, and −100 mV typical V_CE(sat) at −3 A/−60 mA drive, optimized for high-current switching in relay, lamp, and motor driver circuits with ultrasmall CPH3 (SOT-23) package and 0.9 mm mounting height.

For engineers reviewing the CPH3107-TL-E datasheet, pinout, applications, or equivalent options, key selection criteria include verified −15 V breakdown ratings, low saturation voltage under high current, 140 MHz f_T, fast switching (t_on = 30 ns, t_f = 14 ns), and thermal performance on ceramic substrate.

Technical Context

This PNP BJT uses onsemi's MBIT process to achieve high current gain (h_FE = 200–560 at −500 mA) and high-speed switching while maintaining low V_CE(sat). Its design targets discrete power switching where compact size and thermal efficiency are critical.

The device operates within −55°C to +150°C storage range and supports DC and pulsed operation up to −9 A (I_CP), with validated performance across temperature (−25°C to +75°C) in V_CE(sat), h_FE, and f_T curves per official characterization data.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−15 V - Maximum safe collector-emitter voltage before breakdown; defines usable supply headroom in negative-rail switching.
I_C	−6 A - Continuous collector current rating; supports robust load driving without derating at T_a = 25°C on ceramic substrate.
V_CE(sat)	−100 to −150 mV @ −3 A/−60 mA - Low conduction loss enables high-efficiency switching in battery-powered drivers.
f_T	140 MHz - Gain-bandwidth product confirms suitability for >1 MHz PWM control in motor/lamp applications.
t_f	14 ns - Fast fall time minimizes switching transition losses and EMI generation during turn-off.
P_C	0.9 W @ T_a = 25°C on 600 mm² × 0.8 mm ceramic - Enables higher power density than standard SOT-23 in thermally constrained layouts.
Package	CPH3 (JEITA SC-59 / JEDEC TO-236 / SOT-23) - 0.9 mm profile allows ultra-thin PCB designs; 3,000 pcs./reel tape-and-reel (TL-E).

Pinout & Package

CPH3107-TL-E is housed in the CPH3 package - an ultrasmall surface-mount outline identical to SC-59/TO-236/SOT-23, with 0.9 mm maximum mounting height and 0.013 g mass. Pin assignment is standardized: Pin 1 = Base, Pin 2 = Emitter, Pin 3 = Collector.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Current-controlled input terminal; requires −60 mA drive for full saturation at −3 A load.
2	Emitter	Common reference node for PNP operation; connected to higher-potential rail (e.g., −12 V or −5 V supply).
3	Collector	Output terminal sourcing current to load; handles −6 A continuous, −9 A pulsed current with validated thermal path.

Key Features

Feature	Design Value
Low V_CE(sat)	−100 mV typical at −3 A reduces conduction loss by >40% vs. standard PNP BJTs, improving thermal margin in relay drivers.
High-speed switching	30 ns t_on, 14 ns t_f enable clean 1–2 MHz PWM operation without shoot-through risk in half-bridge gate drives.
Ultrasmall CPH3 package	0.9 mm height and SOT-23 footprint allow placement in space-constrained IoT sensor modules and wearable power stages.
High allowable power dissipation	0.9 W on ceramic substrate supports >2× average power vs. FR-4 PCB mounting, extending reliability in industrial motor controls.
MBIT process technology	Enables tight h_FE distribution (200–560) and stable f_T across temperature, reducing calibration overhead in production test.

FAQ

What is the maximum continuous collector current for CPH3107-TL-E?

The CPH3107-TL-E supports −6 A continuous collector current (I_C) when mounted on a 600 mm² × 0.8 mm ceramic substrate at T_a = 25°C. Derating is required above 25°C ambient per the PC–Ta curve in the official datasheet. This rating enables direct replacement of larger-package transistors in space-constrained relay and motor driver designs without thermal compromise.

Does CPH3107-TL-E have Pb-free and RoHS-compliant packaging?

Yes, CPH3107-TL-E is explicitly marked "Pb Free" in the ordering information and complies with RoHS Directive 2011/65/EU. The TL-E suffix denotes lead-free, halogen-free embossed tape-and-reel packaging with 3,000 units per reel-fully compatible with standard SMT reflow profiles and environmental compliance requirements for industrial and automotive end equipment.

What is the typical V_CE(sat) of CPH3107-TL-E at rated current?

The typical collector-to-emitter saturation voltage (V_CE(sat)) of CPH3107-TL-E is −100 mV at I_C = −3 A and I_B = −60 mA, with a maximum of −150 mV under the same conditions. This low saturation voltage directly reduces conduction losses and self-heating, making CPH3107-TL-E especially effective in battery-powered lamp and relay drivers where efficiency and thermal management are critical.

Can CPH3107-TL-E be used in high-frequency switching applications?

Yes, CPH3107-TL-E has a gain-bandwidth product (f_T) of 140 MHz and switching times of t_on = 30 ns and t_f = 14 ns, confirming suitability for PWM frequencies up to 2 MHz in well-designed layouts. Its performance is validated across temperature (−25°C to +75°C), and the CPH3 package's low parasitic capacitance (C_ob = 82 pF at −10 V) supports clean edge integrity in fast-switching motor and flash circuits.

What is the pin configuration and package type of CPH3107-TL-E?

CPH3107-TL-E uses the CPH3 package (JEITA SC-59 / JEDEC TO-236 / SOT-23), with Pin 1 = Base, Pin 2 = Emitter, Pin 3 = Collector. The package measures 2.9 mm × 1.6 mm × 0.9 mm and features a 0.9 mm maximum mounting height-enabling ultra-thin PCB assemblies. Land pattern and embossed taping specifications are documented in the official onsemi outline drawing EN6077C.
