Product details
Overview
CPH3215-TL-H from onsemi is a PNP bipolar junction transistor in SC-59 (SOT-23) package, rated for −30 V VCEO, −1.5 A IC, and 150 mV typical VCE(sat) at IC = −750 mA / IB = −15 mA. It delivers high-speed switching (ton = 35 ns, tf = 30 ns), fT = 500 MHz, and operates up to 150°C junction temperature. It is used in relay drivers and motor control circuits requiring low saturation voltage and compact mounting.
For engineers reviewing the CPH3215-TL-H datasheet, pinout, applications, or equivalent options, key selection criteria include verified PNP polarity, −30 V breakdown rating, 500 MHz fT, 150 mV VCE(sat) under specified bias, and halogen-free compliance confirmed for this exact TL-H variant.
Technical Context
The CPH3215-TL-H is a discrete PNP BJT fabricated using onsemi's MBIT process, optimized for low VCE(sat) and high-speed switching. Its electrical behavior is defined by fixed base-emitter and collector-base junction characteristics, with guaranteed V(BR)CEO = −30 V and hFE = 200–560 at VCE = −2 V, IC = −100 mA.
It operates within a −55°C to +150°C storage range and supports pulsed collector current up to −3 A. Thermal performance is specified for mounting on a 600 mm² ceramic substrate, delivering 0.9 W power dissipation at Ta = 25°C - de-rated linearly above that ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −30 V - Maximum safe collector-to-emitter voltage before breakdown in common-emitter configuration |
| IC | −1.5 A - Continuous DC collector current rating, defining maximum steady-state load drive capability |
| VCE(sat) | 150–225 mV @ IC = −750 mA / IB = −15 mA - Low saturation voltage enables high-efficiency switching in power stages |
| fT | 500 MHz - Gain-bandwidth product confirming suitability for high-frequency switching up to ~100 MHz practical operation |
| hFE | 200–560 @ VCE = −2 V, IC = −100 mA - DC current gain range used to size base drive resistor networks |
| PC | 0.9 W @ Ta = 25°C on ceramic substrate - Power handling capacity determines heatsinking requirements |
| ton/tf | 35 ns / 30 ns - Fast turn-on and fall times support PWM frequencies >5 MHz in digital switching applications |
Pinout & Package
CPH3215-TL-H uses the CPH3 package - identical to JEITA SC-59 and JEDEC TO-236/SOT-23 - with 0.9 mm max mounting height, 3-pin surface-mount configuration, and halogen-free, Pb-free construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control terminal; requires negative bias relative to emitter to forward-bias PNP junction and enable conduction |
| 2 | Emitter | Current source terminal; connected to higher potential (e.g., VCC) in high-side switch configurations |
| 3 | Collector | Current sink terminal; delivers load current to ground or lower-potential node when transistor is saturated |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) | 150 mV typical at IC = −750 mA - reduces conduction loss and self-heating in high-current switching |
| High fT | 500 MHz - supports fast edge rates and stable operation in high-frequency driver and amplifier stages |
| Ultrasmall SOT-23 footprint | 2.9 × 1.6 mm body, 0.9 mm height - enables dense PCB layouts in space-constrained motor and relay modules |
| Halogen-free & Pb-free | Complies with IEC 61249-2-21 and RoHS - meets environmental compliance requirements for industrial and consumer end products |
| High power dissipation | 0.9 W on ceramic substrate - allows direct mounting without auxiliary heatsink in <1 W load applications |
Applications
| Relay Drivers | Lamp Drivers |
|---|---|
Use Scenario: Driving electromagnetic relays in PLC I/O modules where fast turn-off minimizes contact arcing and improves lifetime. IC Role / Device Role / Timing Role: High-side PNP switch controlling relay coil current path from 12–24 V supply to ground. Use Value: 35 ns ton and 30 ns tf reduce coil energy decay time; 150 mV VCE(sat) limits power loss to <113 mW at 750 mA. |
Use Scenario: Switching incandescent or LED indicator lamps in automotive dashboards and industrial HMI panels. IC Role / Device Role / Timing Role: Low-loss PNP current sink enabling precise on/off control of lamp current up to 1.5 A. Use Value: Guaranteed −30 V VCEO withstands load dump transients; halogen-free construction satisfies automotive material compliance. |
| Motor Drivers | Strobe Circuits |
Use Scenario: Controlling small DC brush motors (e.g., cooling fans, actuators) in embedded systems with PWM-based speed regulation. IC Role / Device Role / Timing Role: Single-stage PNP switch in half-bridge high-side position, paired with N-channel MOSFET or diode flyback. Use Value: 500 MHz fT ensures stable gain at PWM edges; 0.9 W PC supports continuous 1 A operation with minimal thermal derating. |
Use Scenario: Triggering xenon flash tubes or high-intensity LED strobes in security cameras and machine vision lighting. IC Role / Device Role / Timing Role: Fast-switching PNP pulse generator delivering short-duration, high-current pulses to flash capacitor discharge paths. Use Value: 225 mV max VCE(sat) preserves pulse amplitude; 3 A ICP rating handles peak strobe currents without secondary breakdown. |
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 | VCEO = −40 V, IC = −200 mA, VCE(sat) = 400 mV @ IC = −10 mA - lower current, higher saturation voltage | Not suitable for >500 mA loads; limited to signal-level switching and logic inversion | Select only for low-power biasing or digital logic; avoid for motor/relay drive where CPH3215-TL-H's 1.5 A rating is required. |
| PN2907A | VCEO = −60 V, IC = −600 mA, VCE(sat) = 1.6 V @ IC = −500 mA - significantly higher saturation loss and slower switching (tf ≈ 250 ns) | Compatible in legacy through-hole designs but unsuitable for high-efficiency or high-frequency PWM use cases | Choose only for cost-sensitive, non-speed-critical replacements where PCB layout change to SOT-23 is not feasible. |
Compared with MMBT3906LT1G and PN2907A, the CPH3215-TL-H provides superior current handling, lower conduction loss, and faster switching - making it the preferred choice for modern compact relay, lamp, and motor driver designs requiring both efficiency and miniaturization.

FAQ
What is the polarity and transistor type of CPH3215-TL-H?
The CPH3215-TL-H is a PNP bipolar junction transistor. Its polarity is confirmed by negative absolute maximum ratings (e.g., VCEO = −30 V, IC = −1.5 A) and electrical characteristics tables specifying PNP test conditions throughout the official datasheet. This distinguishes it from the NPN CPH3115-TL-H in the same family.
Does CPH3215-TL-H meet halogen-free and RoHS requirements?
Yes, the "-H" suffix in CPH3215-TL-H explicitly denotes halogen-free and Pb-free construction, verified in the Ordering Information table and Product & Package Information section of the datasheet. It complies with IEC 61249-2-21 and EU RoHS Directive 2011/65/EU.
What is the maximum pulsed collector current rating for CPH3215-TL-H?
The CPH3215-TL-H has a rated collector current pulse (ICP) of −3 A, specified under transient conditions with 100 μs pulse width and ≤1% duty cycle. This rating enables short-duration surge handling in relay coil de-energization or strobe discharge applications.
Can CPH3215-TL-H be used in place of CPH3115-TL-H?
No - CPH3215-TL-H is PNP while CPH3115-TL-H is NPN. Their complementary polarities mean they cannot substitute directly without circuit redesign. Pinout is identical (Base/Emitter/Collector), but biasing, current flow direction, and system-level interface logic are inverted between the two.
What is the thermal resistance junction-to-ambient for CPH3215-TL-H?
The datasheet does not specify RθJA directly, but provides derated power dissipation vs. ambient temperature. At Ta = 25°C on a 600 mm² ceramic substrate, PC = 0.9 W. Using θJA = (Tj(max) − Ta) / PC, the implied RθJA is approximately 139°C/W - valid only under that exact mounting condition.
