Product details

Overview

CPH3215-TL-E from onsemi is a PNP bipolar junction transistor rated for −30 V V_CEO, −1.5 A I_C, with low V_CE(sat) of −150 mV at I_C = −750 mA / I_B = −15 mA, f_T = 500 MHz, and packaged in SC-59 (CPH3). It serves as a high-speed switching device in relay and lamp driver circuits.

For engineers reviewing the CPH3215-TL-E datasheet, pinout, applications, or equivalent options, key selection criteria include its PNP polarity, −30 V breakdown rating, ultrasmall 0.9 mm mounting height, Pb-free TL taping, and verified performance under pulsed I_C = −3 A conditions.

Technical Context

The CPH3215-TL-E is a discrete PNP BJT fabricated using onsemi's MBIT process, optimized for low saturation voltage and high-speed switching. Its electrical behavior is defined by h_FE = 200–560 at V_CE = −2 V, I_C = −100 mA, and switching times of t_on = 35 ns, t_stg = 205 ns, t_f = 30 ns under specified test conditions.

Thermal performance is characterized by 0.9 W P_C on a 600 mm² ceramic substrate and T_j = 150 °C maximum junction temperature. The device operates within −55 °C to +150 °C storage range and supports DC and pulsed operation up to I_CP = −3 A.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MMBT3906LT1G	V_CEO = −40 V, I_C = −200 mA, V_CE(sat) = −300 mV @ I_C = −10 mA - lower current, higher saturation voltage	Not suitable for >500 mA loads; limited to low-power signal switching	Select when only low-current logic-level inversion is needed and board space allows larger SOT-23 variant
DXT3906PSQ-13	V_CEO = −40 V, I_C = −1 A, V_CE(sat) = −250 mV @ I_C = −500 mA - higher voltage rating but higher saturation loss	Acceptable for 1 A relay/motor loads but dissipates ~1.7× more heat than CPH3215-TL-E at same current	Choose if −40 V margin is critical and thermal headroom exists; avoid where <200 mV V_CE(sat) is required

Compared with MMBT3906LT1G and DXT3906PSQ-13, the CPH3215-TL-E delivers superior current capacity (−1.5 A), lowest V_CE(sat) (−150 mV), and highest f_T (500 MHz), making it optimal for high-efficiency, high-speed PNP switching where thermal and timing constraints are tight.

FAQ

What is the polarity and transistor type of CPH3215-TL-E?

The CPH3215-TL-E is a PNP bipolar junction transistor. Its polarity is confirmed by negative absolute maximum ratings (e.g., V_CEO = −30 V, I_C = −1.5 A) and electrical characteristics tables specifying PNP operation, including V_BE(sat) = −0.85 V and collector-emitter voltage polarity in all curves. This distinguishes it from the NPN CPH3115-TL-E in the same family.

What does the "TL-E" suffix indicate in CPH3215-TL-E?

The "TL-E" suffix in CPH3215-TL-E denotes embossed tape-and-reel packaging (TL) with Pb-free (E) compliance per JEDEC J-STD-609. It specifies 3,000 units per reel, RoHS-compliant finish, and halogen-free materials - distinct from the "TL-H" variant which adds halogen-free certification beyond Pb-free.

Can CPH3215-TL-E replace CPH3115-TL-E in a circuit?

No - CPH3215-TL-E (PNP) and CPH3115-TL-E (NPN) have opposite polarities and complementary electrical behaviors. Swapping them would invert switching logic and likely cause circuit failure. Their pinouts are identical (Base–Emitter–Collector), but voltage/current polarities are reversed; CPH3215-TL-E requires negative base drive relative to emitter.

What is the maximum pulsed collector current rating for CPH3215-TL-E?

The CPH3215-TL-E has a maximum pulsed collector current I_CP of −3 A, specified under single-pulse conditions with 100 μs pulse width and DC ≤ 1%. This rating is validated in the Absolute Maximum Ratings table and supported by transient thermal curves showing safe operation up to I_CP = −3 A at T_a = 25 °C.

Is CPH3215-TL-E suitable for high-frequency switching above 10 MHz?

The CPH3215-TL-E has an f_T of 500 MHz, indicating intrinsic high-frequency capability. However, practical switching above 10 MHz requires careful PCB layout (minimized parasitic inductance/capacitance), appropriate base drive strength, and load impedance matching. Its 35 ns t_on and 30 ns t_f support clean edges in such designs, but system-level validation is required.
