Product details
Overview
BCR 198T E6327 from Infineon Technologies is a PNP silicon digital transistor with integrated bias resistors (R1 = R2 = 47 kΩ), designed for low-power switching, level-shifting, and interface driver functions in compact logic circuits. It features VCEO = 50 V, IC = 70 mA, VCE(sat) ≤ 0.3 V at IC = 10 mA/IB = 0.5 mA, fT = 190 MHz, and operates up to Tj = 150 °C - used in portable MCU I/O buffering and LED driver stages.
For engineers reviewing the BCR 198T E6327 datasheet, BCR 198T E6327 pinout, BCR 198T E6327 application, or BCR 198T E6327 equivalent, key selection criteria include built-in resistor matching (R1/R2 = 0.9–1.1), SOT323 package thermal resistance (RthJS ≤ 165 K/W), input voltage thresholds (Vi(on) = 1–3 V, Vi(off) = 0.8–1.5 V), and guaranteed hFE ≥ 70 at 5 V.
Technical Context
This device integrates two precision-matched bias resistors (R1, R2) directly into a single PNP bipolar junction transistor die, eliminating external base-resistor layout and reducing component count in high-density digital interface designs. Its internal resistor network enables direct TTL/CMOS-level signal compatibility without pull-up/down components.
The BCR 198T variant uses an SC75 (SOT323) package with 3-pin configuration (B-E-C), optimized for surface-mount assembly and thermal performance under pulsed loads. Electrical behavior is characterized at TA = 25 °C with pulse test conditions (t < 300 µs, duty < 2%) applied for saturation and gain measurements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - supports rail-to-rail switching across 3.3 V and 5 V logic domains without breakdown risk |
| IC | 70 mA - sufficient drive capability for small-signal loads including LEDs, relays, and gate inputs |
| VCE(sat) | ≤ 0.3 V at IC = 10 mA - minimizes power loss and self-heating in active-switching mode |
| fT | 190 MHz - enables reliable operation in high-speed digital edge detection and clock buffering |
| R1 / R2 | 47 kΩ ±30% each, ratio 0.9–1.1 - ensures consistent turn-on/off thresholds across production lots |
| hFE | ≥ 70 at VCE = 5 V, IC = 5 mA - guarantees stable current amplification in common-emitter switch configurations |
| RthJS | ≤ 165 K/W - allows sustained 200 mW dissipation at board-level soldering point temperature ≤ 109 °C |
Pinout & Package
BCR 198T E6327 is housed in an SC75 (SOT323) plastic surface-mount package measuring 2.1 × 1.25 × 0.95 mm, with gull-wing leads and moisture sensitivity level (MSL) 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Base terminal | Connected internally to R1 and R2; accepts logic-level input without external biasing |
| 2 (E) | Emitter terminal | Common emitter node; referenced to system ground or negative rail in PNP switching |
| 3 (C) | Collector terminal | Output node driving load to VCC; sinks current when transistor is active |
Key Features
| Feature | Design Value |
|---|---|
| Integrated dual bias resistors | R1 = R2 = 47 kΩ ±30%, matched within ±10% ratio - eliminates discrete resistor placement and improves layout density |
| Guaranteed DC current gain | hFE ≥ 70 at 5 V - ensures predictable on-state current in logic-level driven switches |
| Low saturation voltage | VCE(sat) ≤ 0.3 V - reduces conduction loss and thermal stress during continuous operation |
| High-frequency response | fT = 190 MHz - supports clean signal integrity in fast edge-rate applications like data line buffering |
| Thermal robustness | Junction-to-solder-point resistance ≤ 165 K/W - enables reliable operation in thermally constrained PCB areas |
Applications
| LED Driver Stage | MCU I/O Level Shifter |
|---|---|
Use Scenario: Driving 20 mA indicator LEDs from 3.3 V microcontroller GPIO pins with open-drain or active-low output configuration. IC Role / Device Role / Timing Role: PNP digital switch sinking current from VCC through LED to emitter-ground path. Use Value: Built-in R1/R2 eliminates need for two external resistors, saving 2.5 mm² PCB area per channel and ensuring consistent brightness control. | Use Scenario: Translating 1.8 V or 3.3 V logic outputs to 5 V-tolerant peripheral interfaces (e.g., EEPROM, sensor bus lines). IC Role / Device Role / Timing Role: Active-low level translator providing inverted but rail-compatible voltage translation. Use Value: Vi(on) = 1–3 V and Vi(off) = 0.8–1.5 V enable reliable recognition of sub-2 V logic highs while rejecting noise below 0.8 V. |
| Relay Coil Driver | Logic Inverter Buffer |
Use Scenario: Switching 12 V relay coils drawing ≤ 50 mA in industrial control modules with isolated low-voltage logic sections. IC Role / Device Role / Timing Role: High-side switch controlling coil energization via collector-connected load and grounded emitter. Use Value: VCEO = 50 V and IC = 70 mA provide 2× safety margin over typical 12 V/40 mA relay requirements. | Use Scenario: Inverting TTL/CMOS signals in timing-critical paths such as clock distribution or reset propagation. IC Role / Device Role / Timing Role: Single-transistor inverter stage with defined propagation delay governed by fT and load capacitance. Use Value: fT = 190 MHz supports sub-5 ns rise/fall times into 15 pF loads, preserving signal edge fidelity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP digital transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC807-40,115 | No integrated bias resistors; requires external RB for base drive; hFE = 250–630 (wider spread) | Suitable where adjustable gain or higher current drive (>100 mA) is needed; not drop-in for resistorless design | Select when precise hFE control or higher IC capability is required, and board space permits external resistor placement. |
| DTC114YKAT146 | PNP with R1 = 10 kΩ, R2 = 47 kΩ; lower VCEO = 50 V but tighter Vi(on) spec (1.4–2.4 V); SOT-23 package | Better suited for 1.8 V logic interfacing due to lower threshold; smaller footprint but higher thermal resistance (RthJS ≤ 240 K/W) | Prefer for ultra-low-voltage systems or space-constrained layouts where 1.8 V compatibility outweighs thermal margin needs. |
Compared with BCR 198T E6327, BC807-40 offers higher gain flexibility at the cost of added passives, while DTC114YKAT146 trades thermal performance for tighter input thresholds and smaller size - choice depends on whether resistor integration, thermal headroom, or logic-voltage alignment is prioritized.

FAQ
What is the maximum continuous collector current for BCR 198T E6327?
The absolute maximum continuous collector current is 70 mA at TS ≤ 109 °C. Derating applies above this temperature: total power dissipation drops linearly to zero at 150 °C junction temperature. Pulse operation allows higher peak currents if duty cycle and pulse width comply with the permissible pulse load curves in the datasheet.
Does BCR 198T E6327 require external base resistors?
No - it integrates two precision-matched bias resistors (R1 = R2 = 47 kΩ) internally, enabling direct connection of logic-level signals to the base terminal. This eliminates the need for external pull-up or current-limiting resistors in standard switching configurations.
Can BCR 198T E6327 be used in 1.8 V logic systems?
Yes - its Vi(on) range (1–3 V) and Vi(off) range (0.8–1.5 V) allow reliable turn-on with 1.8 V CMOS outputs, though margin is reduced versus 3.3 V systems. For robust 1.8 V operation, verify actual signal overshoot and noise immunity in the target PCB environment.
What is the thermal resistance from junction to solder point for this part?
RthJS is rated ≤ 165 K/W for the BCR 198T variant in SOT323 (SC75) package. This value is measured under standardized JEDEC test conditions and reflects heat transfer efficiency from the silicon die to the PCB copper pad via the lead frame and solder joint.
