Product details

Overview

PMBTA06,235 from Nexperia is an NPN general-purpose bipolar junction transistor in SOT23 package, designed for low-voltage switching and linear amplification with V_CEO = 80 V, I_C = 500 mA, and h_FE ≥ 100 at I_C = 10 mA. It operates across −65 °C to +150 °C ambient and serves in telephony interface stages, line driver circuits, and signal conditioning blocks where compact size and stable DC gain are required.

For engineers reviewing the PMBTA06,235 datasheet, PMBTA06,235 pinout, PMBTA06,235 application, or PMBTA06,235 equivalent, this page delivers verified electrical parameters, validated SOT23 terminal mapping, real-world use cases in professional comms hardware, and two functionally aligned alternatives with documented differences in gain profile and saturation behavior.

Technical Context

This discrete NPN transistor uses silicon planar epitaxial technology with a base-emitter junction optimized for low V_BE (≤1.2 V at I_C = 100 mA) and high DC current gain stability across temperature. Its breakdown ratings-V_(BR)CEO = 80 V and V_(BR)EBO = 4 V-define safe operating limits for low-power analog and digital switching.

The device exhibits f_T = 100 MHz at V_CE = 2 V, I_C = 10 mA, enabling use in audio-frequency amplifiers and medium-speed digital logic interfaces. Thermal resistance R_th(j-a) = 500 K/W on FR4 PCB confirms suitability for non-heat-sinked, space-constrained layouts.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	80 V - Maximum collector-emitter voltage before breakdown; sets upper rail limit for 24 V/48 V telecom supply rails.
I_C	500 mA - Continuous collector current rating; supports relay drivers and LED array switches without forced cooling.
h_FE	≥100 at V_CE = 1 V, I_C = 10 mA - Ensures predictable base drive requirements in Class-A amplifier bias networks.
V_CE(sat)	≤0.25 V at I_C = 100 mA, I_B = 10 mA - Minimizes conduction loss in saturated-switch applications like power-on reset circuits.
f_T	100 MHz - Enables stable small-signal amplification up to mid-audio band without phase inversion risk.
R_th(j-a)	500 K/W - Confirms thermal viability on standard FR4 with 35 µm copper; no heatsink needed below 125 mW dissipation.

Pinout & Package

SOT23 plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body; JEDEC TO-236AB compliant.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Control input node; requires ≤10 mA base drive for full saturation at 100 mA collector load.
2	Emitter (E)	Common reference terminal; tied to ground or negative rail in common-emitter configurations.
3	Collector (C)	Output current path; connects to load or next stage; rated for 80 V reverse bias when base open.

Key Features

Feature	Design Value
High DC current gain	h_FE ≥ 100 at 10 mA ensures minimal base current overhead in battery-powered sensor interfaces.
Low V_CE(sat)	≤0.25 V reduces power loss in always-on status indicators and logic-level translators.
Wide temperature range	−65 °C to +150 °C operation supports deployment in industrial gateways and outdoor telecom enclosures.
Small footprint	SOT23 package enables high-density routing on 4-layer PCBs without via stacking under the device.

Applications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC846B,215	h_FE = 200–450 (min 200), V_CEO = 65 V, P_tot = 300 mW	Higher gain but lower breakdown voltage; unsuitable for 80 V telecom surge protection circuits.	Select when precise current mirroring or low-base-drive amplification is prioritized over voltage margin.
MMBT3904LT1G	h_FE = 100–300 (min 100), V_CEO = 40 V, R_th(j-a) = 400 K/W	Lower V_CEO and better thermal resistance; limited to ≤36 V systems with tighter thermal budgets.	Choose for cost-sensitive consumer electronics where 40 V rail compliance suffices and board area is constrained.

Compared with BC846B,215 and MMBT3904LT1G, PMBTA06,235 uniquely balances 80 V breakdown, 500 mA current, and SOT23 thermal performance-making it optimal for professional communication equipment requiring both voltage headroom and reliability across extended temperature.

FAQ

Is PMBTA06,235 automotive-qualified?

No. Per Nexperia's 2022 data sheet revision, PMBTA06,235 is explicitly designated as non-automotive qualified. It lacks AEC-Q101 stress testing and is not warranted for safety-critical vehicle systems. Automotive alternatives include the PMBTA06-Q series, which undergoes extended temperature cycling and humidity testing.

What is the maximum allowable base current for continuous operation?

The absolute maximum peak base current is 200 mA per pulse (t_p ≤ 1 ms), but continuous base current must be limited to ensure I_C ≤ 500 mA and P_tot ≤ 250 mW. At V_CE = 1 V and I_C = 100 mA, typical I_B is 10 mA-so sustained base drive above 15 mA risks thermal overload on standard FR4.

Can PMBTA06,235 replace BC547 in existing designs?

Only with layout and bias verification. While both are NPN transistors, PMBTA06,235 has higher V_CEO (80 V vs. 45 V) and different SOT23 pinout (B-E-C vs. E-B-C for BC547 in TO-92). Direct substitution requires PCB pad remapping and recalculation of base resistor values due to h_FE distribution differences.

Does PMBTA06,235 support reflow soldering per J-STD-020?

Yes. Nexperia's data sheet specifies compatibility with standard lead-free reflow profiles. The recommended footprint (Fig. 9) uses 0.6 mm solder lands and 0.7 mm solder paste stencil openings. Peak temperature must not exceed 260 °C for ≤10 seconds, matching J-STD-020 Level 2a requirements for SOT23 packages.
