Product details

Overview

BC807-40HR from Nexperia is a PNP general-purpose bipolar junction transistor in SOT23 package, rated for −45 V V_CEO, −500 mA continuous collector current, and DC current gain (h_FE) of 250–600 at V_CE = −1 V, I_C = −100 mA. It operates reliably up to 175 °C junction temperature and serves as a robust switching or linear amplification device in low-voltage power management and signal conditioning circuits.

For engineers reviewing the BC807-40HR datasheet, BC807-40HR pinout, BC807-40HR application, or BC807-40HR equivalent, this page delivers verified electrical parameters, thermal derating behavior, SOT23 terminal mapping, real-world use cases in industrial control and automotive subsystems, and validated alternative transistors with documented h_FE and saturation voltage differences.

Technical Context

This transistor implements a silicon planar epitaxial PNP structure optimized for stable DC current gain across wide temperature ranges (−55 °C to +175 °C) and pulse operation (t_p ≤ 300 μs, duty cycle ≤ 0.02). Its base-emitter and collector-emitter saturation voltages are characterized under defined I_C/I_B ratios (e.g., 10, 50, 100), enabling predictable drive requirements in switch-mode designs.

The device exhibits frequency-dependent capacitance: C_c = 7 pF at V_CB = −10 V and C_e = 37 pF at V_EB = −0.5 V, supporting moderate-speed switching (f_T = 80 MHz at V_CE = −5 V, I_C = −10 mA). Thermal resistance varies with PCB layout - R_th(j-a) ranges from 280 K/W (4-layer copper, 1 cm² collector pad) to 470 K/W (single-sided FR4).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−45 V: Maximum safe collector-emitter voltage with base open; defines off-state blocking capability in high-side switch configurations.
I_C	−500 mA: Continuous DC collector current at T_amb = 25 °C; sets steady-state load drive limit without forced cooling.
h_FE	250–600 at V_CE = −1 V, I_C = −100 mA: Confirmed DC current gain range enabling precise base drive calculation for saturation.
V_CE(sat)	≤ −700 mV at I_C = −500 mA, I_B = −50 mA: Low saturation voltage minimizes conduction loss in power switching applications.
T_j(max)	+175 °C: Maximum junction temperature rating; supports operation in engine bay, motor control, and industrial enclosures without derating below ambient.
f_T	80 MHz at V_CE = −5 V, I_C = −10 mA: Transition frequency confirms suitability for audio-frequency amplification and sub-MHz digital switching.
P_tot	540 mW on 4-layer FR4 with 1 cm² collector pad: Total power dissipation limit defining thermal design margin under worst-case PCB layout.

Pinout & Package

SOT23 (TO-236AB) plastic surface-mount package with 3 leads; compact 2.9 × 1.3 × 1.0 mm footprint compatible with standard reflow and wave soldering profiles per Nexperia's recommended land patterns.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Control terminal; requires current-limited drive (I_B ≤ −50 mA typical for full saturation at I_C = −500 mA).
2	Emitter (E)	Current source terminal; connected to higher potential rail in PNP high-side switch configuration.
3	Collector (C)	Load connection terminal; sinks current to ground or lower-potential node when transistor is active.

Key Features

Feature	Design Value
Three h_FE grades	BC807-16H (100–250), BC807-25H (160–400), BC807-40H (250–600): Enables precise gain matching for analog biasing or consistent switching thresholds across production batches.
High-temperature operation	Junction rating up to +175 °C: Allows deployment in under-hood automotive modules, motor drivers, and industrial PLC I/O stages without external heatsinking.
Low V_CE(sat)	≤ −700 mV at I_C = −500 mA: Reduces power loss by >30% versus legacy BC807-25 variants, improving efficiency in battery-powered systems.
Thermal performance scalability	R_th(j-a) from 280–470 K/W depending on PCB copper mass: Supports flexible thermal design-from cost-sensitive single-layer boards to high-reliability 4-layer layouts.
Standard SOT23 footprint	Compatible with JEDEC TO-236AB outline and IPC-7351B land patterns: Ensures drop-in replacement capability and automated assembly compatibility.

Applications

Industrial Motor Control

Automotive Body Electronics

Use Scenario: Driving 12 V relay coils and small solenoids in programmable logic controller (PLC) output modules.

IC Role / Device Role / Timing Role: PNP high-side switch controlling coil energization; provides galvanic isolation between microcontroller GPIO and inductive load.

Use Value: V_CEO = −45 V withstands 12 V system transients; h_FE ≥ 250 ensures reliable turn-on with ≤ 2 mA base drive from 3.3 V MCU outputs via level-shifting resistor.

IC Role / Device Role / Timing Role: Low-power PNP switch enabling reverse-polarity protection and load disconnect during sleep mode.

Use Value: T_j = 175 °C rating supports operation near HVAC ducts; V_BE(sat) ≤ −1.2 V guarantees fast turn-off even at −40 °C ambient, preventing ghost illumination.

Consumer Power Management

Medical Diagnostic Equipment

Use Scenario: Enabling/disabling 5 V auxiliary rails in portable ultrasound and ECG monitors using discrete power gating.

IC Role / Device Role / Timing Role: PNP pass transistor in low-dropout linear regulator front-end; regulates input to downstream LDOs.

Use Value: V_CE(sat) ≤ −700 mV limits dropout to <1 V at 300 mA, preserving battery runtime; SOT23 size fits tight board space constraints.

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
BC807-40,115 (Nexperia)	Same h_FE range (250–600) but marked "115" instead of "6U%"; identical electrical specs and SOT23 package.	No functional difference; used interchangeably in all BC807-40H applications including automotive-qualified designs where -Q suffix not required.	Select when sourcing from distributors listing "115" variant; no redesign or qualification needed.
MMBT4403 (ON Semiconductor)	Lower h_FE (100–300), higher V_CE(sat) (≤ −750 mV), same V_CEO (−40 V) and I_C (−600 mA); SOT23-compatible pinout.	Less suitable for low-base-drive applications; requires larger base resistor to achieve same I_C; acceptable in non-critical switching where gain tolerance >30% is acceptable.	Use only if BC807-40HR is unavailable and circuit can tolerate 20% higher V_CE(sat) and reduced gain consistency.

Compared with BC807-40HR, BC807-40,115 offers identical performance and direct substitution, while MMBT4403 trades gain and saturation voltage for broader legacy availability-making it viable only where base drive margin exists and thermal headroom permits higher conduction loss.

FAQ

What is the maximum allowable base current for BC807-40HR?

The absolute maximum peak base current is −200 mA (single pulse, t_p ≤ 1 ms). For continuous operation, base current must be limited to ensure I_C ≤ −500 mA and junction temperature remains ≤ +175 °C. At I_C = −500 mA and h_FE = 250 (minimum), I_B ≈ −2 mA is sufficient for saturation; typical design uses 5–10× this value for margin.

Does BC807-40HR support automotive qualification?

No. Per Nexperia's revision history (Rev. 2, Sept 2025), the BC807H_SER series was explicitly changed to non-automotive qualification. For automotive applications, Nexperia recommends the BC807-Q series (e.g., BC807-40Q), which undergoes AEC-Q101 stress testing and features enhanced reliability screening.

How does thermal resistance vary with PCB construction?

R_th(j-a) ranges from 280 K/W (4-layer FR4, 1 cm² collector pad) to 470 K/W (single-sided FR4, standard footprint). This 68% variation directly impacts allowable power dissipation: at 25 °C ambient, P_tot drops from 540 mW to 320 mW as R_th(j-a) increases, requiring careful layout review for thermally demanding applications.

Can BC807-40HR replace BC807-25H in existing designs?

Yes, with verification. BC807-40HR has higher minimum h_FE (250 vs. 160), enabling lower base drive current and potentially faster switching. However, its higher gain may increase sensitivity to leakage currents in high-impedance bias networks; confirm stability under worst-case temperature and voltage conditions before substitution.
