Product details
Overview
BCV26,215 from Nexperia is a PNP Darlington transistor in SOT23 package, delivering high DC current gain (min. 10,000 at IC = −10 mA), −30 V VCES, and −500 mA IC. It serves as a high-gain switching or amplification stage in low-voltage industrial control interfaces and sensor signal conditioning circuits.
For engineers reviewing the BCV26,215 datasheet, BCV26,215 pinout, BCV26,215 application, or BCV26,215 equivalent, key selection criteria include verified Darlington saturation voltage (VCE(sat) ≤ −1 V at −100 mA), thermal resistance (Rth(j-a) = 500 K/W), and guaranteed hFE ≥ 10,000 under standard bias conditions.
Technical Context
This device implements a two-stage PNP Darlington configuration with integrated base-emitter resistor network absent - requiring external base drive. Its high hFE enables microampere-level base current control of up to −500 mA collector load, while VCES = −30 V and VCBO = −40 V define its safe operating area in low-side switching topologies.
The SOT23 package imposes thermal constraints: Ptot = 250 mW at Tamb ≤ 25 °C, with Rth(j-a) = 500 K/W limiting continuous power handling without PCB copper enhancement. fT = 220 MHz supports moderate-speed switching but not RF applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCES | −30 V: Maximum collector-emitter voltage before breakdown under open-base condition. |
| IC (DC) | −500 mA: Continuous collector current rating; defines max load drive capability in linear or saturated operation. |
| hFE | ≥10,000 @ IC = −10 mA: Ensures <1 µA base current suffices for 10 mA collector load, reducing driver burden. |
| VCE(sat) | ≤ −1 V @ IC = −100 mA, IB = −0.1 mA: Confirms low conduction loss in saturated switch mode. |
| Rth(j-a) | 500 K/W: Thermal resistance limits junction temperature rise to +125 °C at 250 mW dissipation in still air. |
| fT | 220 MHz: Transition frequency indicates usable bandwidth up to ~20–30 MHz for small-signal amplification. |
Pinout & Package
BCV26,215 is housed in a plastic surface-mounted SOT23 (TO-236AB) package, measuring 2.9 mm × 1.3 mm × 1.0 mm with 0.95 mm lead pitch. The package supports reflow soldering per J-STD-020 and is rated for Tj ≤ 150 °C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Input control terminal; requires negative bias relative to emitter to turn on PNP Darlington pair. |
| 2 | Emiter | Common reference terminal; connected to higher potential rail in typical low-side switch configuration. |
| 3 | Collector | Output current terminal; sinks load current to ground or lower-potential node when active. |
Key Features
| Feature | Design Value |
|---|---|
| High DC current gain | hFE ≥ 10,000 at −10 mA ensures ultra-low base drive current requirement. |
| Low saturation voltage | VCE(sat) ≤ −1 V at −100 mA minimizes power loss in switching applications. |
| Robust voltage rating | VCES = −30 V supports operation in 24 V industrial control rails with margin. |
| SOT23 footprint compatibility | Standard 3-pin SOT23 layout enables drop-in replacement in space-constrained PCBs. |
Applications
| Industrial Sensor Interface | Low-Voltage Relay Driver |
|---|---|
Use Scenario: Amplifying weak output signals from resistive temperature detectors (RTDs) or analog pressure sensors before ADC sampling. IC Role / Device Role / Timing Role: High-gain PNP Darlington amplifier stage providing current buffering and level shifting. Use Value: Enables direct interface of µA-level sensor outputs to 3.3 V/5 V microcontroller inputs without op-amp stages. | Use Scenario: Driving 12 V/24 V electromagnetic relays in programmable logic controller (PLC) output modules. IC Role / Device Role / Timing Role: Low-side switch controlling relay coil current with minimal MCU GPIO loading. Use Value: Reduces required base drive current to <1 µA at 10 mA relay coil load, easing isolation design. |
| LED Current Regulator | Power Supply Enable Switch |
Use Scenario: Constant-current LED driver for status indicators in automotive dashboard clusters. IC Role / Device Role / Timing Role: Linear current sink regulating LED current via emitter resistor feedback. Use Value: Maintains stable LED brightness across supply variations due to high hFE-stabilized current mirror behavior. | Use Scenario: Enabling/disabling auxiliary 5 V or 3.3 V LDO outputs in embedded power management subsystems. IC Role / Device Role / Timing Role: High-gain enable switch controlling LDO EN pin or pass-FET gate. Use Value: Allows clean, low-leakage shutdown using a single GPIO with no pull-up/pull-down overhead. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP Darlington transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCV27,215 | NPN complement; identical SOT23 package, matching hFE and VCEO specs but opposite polarity. | Used in high-side switching or complementary push-pull stages where NPN topology is required. | Select when circuit requires NPN Darlington behavior with same gain and voltage ratings. |
| ZTX951 | Higher VCEO (−60 V), lower hFE (min. 500), TO-92 package - larger footprint and thermal mass. | Suitable for higher-voltage industrial controls but incompatible with SOT23 board space constraints. | Choose only if >−30 V blocking is mandatory and PCB layout allows TO-92 placement. |
Compared with BCV26,215, BCV27,215 offers polarity reversal without sacrificing gain or package compatibility, while ZTX951 trades miniaturization and gain for higher voltage tolerance - making BCV26,215 optimal for space-limited, high-gain, ≤−30 V PNP switching.

FAQ
What is the maximum continuous collector current for BCV26,215?
The BCV26,215 is rated for −500 mA DC collector current at Tamb ≤ 25 °C with FR4 PCB mounting. Derating is required above 25 °C ambient - junction temperature must remain ≤ 150 °C, governed by Rth(j-a) = 500 K/W. At 70 °C ambient, max IC drops to approximately −300 mA.
Does BCV26,215 include an internal base-emitter resistor?
No, BCV26,215 is a bare PNP Darlington transistor without integrated bias resistors. External base drive circuitry - such as a series current-limiting resistor or active driver - must be provided. This differs from "digital transistors" like the NSV11201, which integrate R1/R2.
Can BCV26,215 replace BCV46 in the same circuit?
Only if VCES and VCBO requirements are ≤ −30 V and −40 V respectively. BCV46 offers −60 V VCES and −80 V VCBO; substituting BCV26,215 in higher-voltage designs risks premature breakdown. Gain and saturation characteristics are similar, but voltage derating is non-negotiable.
Is BCV26,215 RoHS compliant and halogen-free?
Yes, BCV26,215 conforms to RoHS Directive 2011/65/EU and is halogen-free per Nexperia's product compliance documentation (document ID: Q100001). Lead finish is matte Sn, and the SOT23 mold compound meets IPC-4101D/126 specifications for green materials.
