Product details
Overview
BCV48,115 from Nexperia is a PNP Darlington transistor in SOT89 package, delivering minimum DC current gain of 2000 at −1 mA collector current and up to 10,000 at −100 mA, with −60 V VCE rating and −500 mA continuous collector current. It serves as high-gain switching or amplification stage in low-voltage industrial control interfaces requiring robust current drive with minimal base drive.
For engineers reviewing the BCV48,115 datasheet, BCV48,115 pinout, BCV48,115 application, or BCV48,115 equivalent, key selection criteria include verified Darlington hFE ≥2000 at −1 mA, SOT89 thermal resistance Rth(j-sp) = 16 K/W, −1.5 V VBE(sat) at −100 mA/−0.1 mA, and non-automotive qualification status per revision v.4 (20241008).
Technical Context
The BCV48,115 integrates two cascaded PNP transistors in monolithic Darlington configuration, enabling ultra-high DC current gain while maintaining single-base control. Its structure supports low base drive requirements for driving relays or indicator LEDs from microcontroller GPIOs operating at ≤3.3 V logic levels.
It operates within −65 °C to +150 °C ambient range with absolute maximum VCB0 = −80 V and thermal resistance Rth(j-a) = 96 K/W on FR4 PCB. The device is explicitly non-automotive qualified per revision history, limiting use to industrial, consumer, and commercial applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCE max | −60 V: Supports operation in 48 V rail systems with safety margin |
| IC max | −500 mA continuous: Drives medium-power loads like solenoids or fan motors |
| hFE min | 2000 @ VCE = −5 V, IC = −1 mA: Enables µA-level base current control |
| VBE(sat) | −1.5 V @ IC = −100 mA, IB = −0.1 mA: Confirms Darlington saturation behavior |
| Rth(j-sp) | 16 K/W: Enables 800 mW dissipation before solder point exceeds 150 °C junction limit |
| fT | 220 MHz: Supports switching above audio frequencies but not RF applications |
Pinout & Package
SOT89 (SC-62) plastic surface-mount package: 3-lead, 1.5 mm pitch, 4.5 mm × 2.5 mm × 1.5 mm body, with collector tab thermally connected to PCB mounting pad (6 cm² copper area required per datasheet).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (E) | Emitter | Common reference terminal; connects to most positive rail in PNP Darlington configuration |
| 2 (C) | Collector | Main output terminal; electrically and thermally tied to exposed tab for power dissipation |
| 3 (B) | Base | Control input; requires current-limited drive due to Darlington input impedance |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-high DC current gain | hFE ≥10,000 at −100 mA enables single-stage amplification without cascading transistors |
| Low saturation voltage | VBE(sat) = −1.5 V ensures predictable turn-on threshold under load |
| Thermally optimized package | Rth(j-sp) = 16 K/W allows direct heat transfer to PCB copper, reducing need for heatsinks |
| Robust voltage rating | VCB0 = −80 V provides margin against inductive kickback in relay/solenoid drivers |
Applications
| Industrial Relay Driver | LED Current Amplifier |
|---|---|
Use Scenario: Driving 24 V DC industrial relays with coil resistance ~200 Ω from 3.3 V MCU GPIO. IC Role / Device Role / Timing Role: High-gain PNP Darlington switch providing >100 mA collector current with <100 µA base current. Use Value: Eliminates need for discrete base resistor networks or additional driver stages, reducing BOM count and layout area. | Use Scenario: Controlling high-brightness LED strings (e.g., status indicators, signage) requiring 350–500 mA constant current. IC Role / Device Role / Timing Role: Constant-current sink amplifier with stable hFE across temperature for analog dimming control. Use Value: Maintains consistent LED brightness over −40 °C to +85 °C ambient without feedback compensation. |
| Low-Voltage Power Switch | Signal-Level Amplifier |
Use Scenario: Replacing mechanical switches in battery-powered equipment (e.g., portable test gear) operating from 5–12 V supplies. IC Role / Device Role / Timing Role: Low-input-current power switch enabling push-button latching circuits with nanoamp standby leakage. Use Value: Reduces system quiescent current by >95% compared to standard PNP switches, extending battery life. | Use Scenario: Amplifying weak sensor signals (e.g., thermistor bridge outputs, photodiode currents) before ADC sampling. IC Role / Device Role / Timing Role: High-input-impedance current amplifier converting nA-level signals to mA-level for noise-immune routing. Use Value: Achieves >60 dB signal-to-noise ratio improvement without op-amp biasing complexity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP Darlington transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCV49,115 | NPN complement; identical SOT89 package, matching hFE, VCEO, IC ratings | Requires inverted logic and supply topology; unsuitable for high-side switching where BCV48 excels | Select when NPN high-side sourcing or complementary pair design is required |
| ZTX951 | TO-92 package; hFE min = 1000 @ −10 mA; VCEO = −60 V; IC = −1 A | Larger footprint and higher thermal resistance (Rth(j-a) ≈ 200 K/W); not SMT-compatible | Choose only if through-hole assembly is mandated and higher peak current is needed |
Compared with BCV48,115, BCV49,115 offers functional symmetry but opposite polarity, while ZTX951 trades SMT compatibility and thermal performance for higher peak current and legacy through-hole fit - neither is pin-compatible, and both require schematic and layout revision.

FAQ
Is BCV48,115 qualified for automotive applications?
No. Per revision v.4 (20241008), BCV48,115 is explicitly non-automotive qualified. It lacks AEC-Q101 stress testing and automotive-grade process controls. For automotive use, Nexperia offers separate −Q qualified variants such as BCV48-Q, which must be specified separately and are not interchangeable.
What is the maximum safe continuous power dissipation for BCV48,115 on a standard FR4 PCB?
At Tamb ≤ 25 °C with a 6 cm² copper pad on single-sided FR4, Ptot = 1.3 W is the rated limit. Derating begins at 11.4 mW/°C above 25 °C ambient, reaching zero dissipation at 150 °C junction temperature - consistent with Rth(j-a) = 96 K/W and Tj(max) = 150 °C.
Can BCV48,115 replace BCV28 in existing designs?
No. BCV28 is an NPN small-signal transistor in SOT23 package with hFE = 100–300 and IC = 100 mA - fundamentally different function, polarity, gain, and package. Substitution would require full circuit redesign including polarity inversion, base resistor recalculation, and PCB footprint change.
Does BCV48,115 have built-in ESD protection?
No. The datasheet does not specify any on-chip ESD protection diodes or HBM/CDM ratings. External protection (e.g., series resistors, TVS diodes) is required in handling and end-use environments exceeding ±2 kV HBM, especially in automated assembly or field-replaceable modules.
