Product details

Overview

BCW30,215 from Nexperia is a PNP general-purpose bipolar junction transistor (BJT) in SOT23 package, rated for −32 V V_CEO, −100 mA I_C, and DC current gain (h_FE) of 215–500 at I_C = −2 mA. It serves as a low-power switching and amplification device in signal-level analog and digital interface circuits.

For engineers reviewing the BCW30,215 datasheet, BCW30,215 pinout, BCW30,215 application, or BCW30,215 equivalent, key selection criteria include its PNP polarity, SOT23 footprint compatibility, guaranteed h_FE range, V_CEsat ≤ −300 mV at I_C = −10 mA, and thermal resistance of 500 K/W on FR4 PCB.

Technical Context

This transistor operates in active and saturation regions for linear amplification and digital switching, respectively. Its PNP configuration requires reverse-biased base-emitter junction for conduction, with collector-emitter voltage polarity inverted relative to NPN devices like BCW31/BCW32.

Designed for low-current signal handling, it features low noise figure (≤10 dB at 1 kHz), f_T ≥ 100 MHz, and C_c = 4.5 pF - enabling stable performance in audio preamps, level shifters, and discrete logic inverters up to ~10 MHz.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−32 V: Maximum safe collector-emitter voltage under open-base condition; defines upper rail limit in PNP switch designs.
I_C (DC)	−100 mA: Continuous collector current rating; sets max load drive capability in low-power stages.
h_FE	215–500 at I_C = −2 mA: Confirmed DC current gain range; enables predictable base drive sizing for reliable saturation.
V_CEsat	−80 to −300 mV at I_C = −10 mA: Low saturation voltage ensures minimal power loss and heat generation in switching mode.
R_th(j-a)	500 K/W on FR4: Thermal resistance determines junction temperature rise; limits usable power dissipation to ~250 mW at T_amb = 25 °C.
f_T	≥100 MHz: Transition frequency supports small-signal amplification up to VHF band edges without significant gain roll-off.

Pinout & Package

SOT23 plastic surface-mounted package (TO-236AB), 3-lead, JEDEC-compliant outline with 1.3 mm × 2.9 mm footprint and 0.95 mm pitch.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control terminal; reverse-biased relative to emitter to turn device ON in PNP configuration.
2	Emiter	Current source terminal; connected to higher potential rail in typical common-emitter switch layout.
3	Collector	Current sink terminal; delivers controlled output current to load referenced to lower potential.

Key Features

Feature	Design Value
Guaranteed h_FE range	215–500 at I_C = −2 mA: Enables consistent biasing across production lots without individual trimming.
Low V_CEsat	≤ −300 mV at I_C = −10 mA: Reduces conduction loss in battery-powered or thermally constrained applications.
High f_T	≥100 MHz: Supports broadband signal amplification and fast edge response in pulse circuits.
Low noise figure	≤10 dB at 1 kHz: Suitable for low-level analog signal paths where SNR preservation is critical.

Applications

Audio Pre-amplifier Stage

Level Shifter Circuit

Use Scenario: Amplifying weak microphone or sensor signals before ADC input in portable audio systems.

IC Role / Device Role / Timing Role: PNP BJT configured in common-emitter topology for voltage gain and impedance transformation.

Use Value: Guaranteed h_FE ≥215 ensures stable gain across temperature; low V_CEsat minimizes headroom loss in single-supply 3.3 V designs.

Use Scenario: Translating logic levels between 5 V microcontroller outputs and 3.3 V FPGA inputs.

IC Role / Device Role / Timing Role: Discrete PNP switch implementing active-low level translation with pull-up resistor.

Use Value: Fast f_T ≥100 MHz supports clean edge transitions up to 10 MHz; low C_c = 4.5 pF prevents signal distortion.

Digital Logic Inverter

LED Driver (Low-Side Switch)

Use Scenario: Constructing discrete NOT gates in educational kits or legacy control panels.

IC Role / Device Role / Timing Role: Saturated PNP switch providing inverted logic output with defined high/low voltage thresholds.

Use Value: V_BEsat ≈ −720 mV at I_C = −10 mA ensures predictable threshold behavior; SOT23 footprint allows compact board layout.

Use Scenario: Driving indicator LEDs in industrial HMIs where current < 50 mA and supply ≤ 24 V.

IC Role / Device Role / Timing Role: PNP emitter-follower or common-emitter switch controlling LED anode connection.

Use Value: −100 mA I_C rating accommodates multi-LED strings; R_th(j-a) = 500 K/W permits operation without heatsinking at ambient ≤ 60 °C.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP general-purpose transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BCW32,215	NPN complement; identical SOT23 package, same h_FE range (215–500), but opposite polarity and voltage/current sign convention.	Requires circuit redesign for base drive polarity and supply referencing; not drop-in replaceable.	Select when NPN topology is preferred or complementary pairing with BCW30 is needed in push-pull stages.
MMBT3906LT1G	Onsemi PNP BJT; V_CEO = −40 V, I_C = −200 mA, h_FE = 100–300 at I_C = −10 mA - higher voltage/current but narrower gain spread.	Better suited for higher-voltage switching (e.g., 24 V relay drivers); less ideal for precision low-current gain-critical amps.	Choose for enhanced ruggedness in industrial controls where −40 V rating and −200 mA I_C margin are required.

Compared with BCW30,215, BCW32,215 offers functional symmetry but reversed polarity, while MMBT3906LT1G trades wider h_FE tolerance for higher voltage/current headroom - guiding selection based on topology constraints and system-level stress margins.

FAQ

What is the maximum operating junction temperature for BCW30,215?

The absolute maximum junction temperature (T_j) is 150 °C, as specified in the Limiting Values table. Operation above this temperature risks permanent degradation. Derating is required above 25 °C ambient due to R_th(j-a) = 500 K/W - e.g., max P_tot drops to ~125 mW at T_amb = 75 °C.

Is BCW30,215 pin-compatible with BCW29,215?

Yes - both share identical SOT23 pinout (Pin 1 = Base, Pin 2 = Emitter, Pin 3 = Collector) and mechanical outline. However, BCW29 has lower h_FE (90–260 vs. 215–500) and is not a direct electrical substitute in gain-critical designs.

Can BCW30,215 be used in linear amplifier configurations?

Yes - its specified h_FE, f_T ≥ 100 MHz, and low noise figure (≤10 dB) support Class-A and Class-AB small-signal amplification. Stable operation requires proper biasing to maintain V_CE > 1 V and avoid saturation, per characteristics at T_j = 25 °C.

What marking code identifies BCW30,215 on the device body?

The top-side marking is "C2*", where "*" denotes manufacturing location: "p" = Hong Kong, "t" = Malaysia, "W" = China. This matches the official pinning and ordering information in the Nexperia datasheet revision dated 2004 Jan 13.
