Product details
Overview
BCV61BE6327HTSA1 from Infineon Technologies is an NPN silicon double transistor in SOT-143 package, designed for current mirror applications with matched VBE and tight thermal coupling between T1 and T2. It delivers hFE = 200–420 (BCV61B grade) at IC = 2 mA, VCE = 5 V, VCE(sat) ≤ 200 mV at IC = 100 mA, and is AEC-Q101 qualified for automotive use.
For engineers reviewing the BCV61BE6327HTSA1 datasheet, BCV61BE6327HTSA1 pinout, BCV61BE6327HTSA1 application, or BCV61BE6327HTSA1 equivalent, key selection criteria include matched transistor pair performance, low saturation voltage under high-current switching, thermal stability across temperature, and RoHS-compliant SOT-143 packaging for space-constrained analog and power management circuits.
Technical Context
The BCV61B is a monolithic dual NPN transistor with physically adjacent emitters and collectors to ensure <0.3°C thermal gradient between devices during operation. Its matching specification - IC1/IC2 = 0.7–1.3 at IE2 = 0.5 mA and VCE1 = 5 V - enables precision current mirroring without external emitter degeneration resistors.
It operates with VCEO = 30 V, VCB0 = 30 V, and VEB0 = 6 V per transistor, supporting biasing in common-emitter and common-base configurations up to 150 °C junction temperature. The fT = 250 MHz and Ccb = 0.95 pF support moderate-frequency analog signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 30 V - Enables use in 24 V automotive supply rails with margin for transients |
| hFE (T1, IC=2 mA) | 200–420 - Ensures stable current gain across production lots for predictable mirror ratio |
| VCE(sat) (IC=100 mA) | ≤200 mV - Minimizes conduction loss in high-side current-sense or load-switching paths |
| IC1/IC2 Matching | 0.7–1.3 at IE2=0.5 mA - Supports ±30% current ratio tolerance without trimming resistors |
| fT | 250 MHz - Allows use in audio preamp stages and feedback loops up to ~50 MHz |
| RthJS | ≤170 K/W - Limits junction-to-solder-point temperature rise to <51 °C at 300 mW dissipation |
Pinout & Package
SOT-143 (SC-70-4) surface-mount package: 1.6 mm × 2.9 mm footprint, 1.1 mm height, lead-free matte tin plating, rated for reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (C2) | Collector of Transistor T2 | Provides second mirrored output node; shares thermal mass with T1 collector (Pin 2) |
| 2 (C1) | Collector of Transistor T1 | Primary current mirror output; electrically isolated but thermally coupled to Pin 1 |
| 3 (E1) | Emitter of Transistor T1 | Reference input node for mirror configuration; tied directly to base of T2 in classic Wilson mirror |
| 4 (E2) | Emitter of Transistor T2 | Matched emitter path enabling differential current sensing or active load implementation |
Key Features
| Feature | Design Value |
|---|---|
| Monolithic dual-NPN topology | Guarantees sub-degree thermal tracking between T1 and T2 for stable current mirroring over temperature |
| AEC-Q101 qualification | Validated for automotive under-hood applications including engine control modules and body electronics |
| VBE matching | Enables <±2 mV VBE offset between transistors at matched currents, reducing mirror error |
| Low VCE(sat) | Reduces power loss in high-current mirror legs (e.g., 100 mA load), improving efficiency in linear regulators |
Applications
| Automotive Current Mirror | High-Voltage Linear Regulator |
|---|---|
Use Scenario: Precision current reference generation in engine ECU sensor biasing circuits. IC Role / Device Role / Timing Role: Dual-transistor current mirror providing temperature-stable reference current for oxygen sensor heaters. Use Value: Maintains <±3% current accuracy from −40 °C to +125 °C without trimming, reducing calibration overhead. | Use Scenario: Active pass element and current-limit sense in 24 V automotive linear regulators. IC Role / Device Role / Timing Role: T1 acts as series pass transistor; T2 mirrors load current for foldback protection. Use Value: Enables fast response to short-circuit events with matched thermal behavior, preventing thermal runaway. |
| Differential Amplifier Input Stage | LED Driver Current Control |
Use Scenario: Input pair in rail-to-rail op-amps operating from 5 V supply in ADAS camera modules. IC Role / Device Role / Timing Role: Matched NPN pair forms high-gain, low-offset differential input stage. Use Value: Achieves <10 µV input offset drift over temperature due to monolithic VBE tracking. | Use Scenario: Constant-current sink for RGB LED backlighting in infotainment displays. IC Role / Device Role / Timing Role: T1 sets LED current; T2 monitors and regulates via feedback to driver IC. Use Value: Delivers <±5% brightness uniformity across 3–5 LEDs without individual current-setting resistors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-NPN current mirror applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCV62B,6327 | PNP/NPN complementary pair instead of NPN/NPN; VCEO = 30 V, hFE = 200–420, same SOT-143 package | Supports complementary mirror topologies (e.g., Widlar, cascode) but not direct replacement in NPN-only designs | Select when designing push-pull or rail-splitting current sources requiring both polarities |
| MBT3904DW1T1G | Two discrete 2N3904 transistors in SOT-363; no monolithic thermal coupling; hFE = 100–300; VCE(sat) = 300 mV @ 100 mA | Lacks guaranteed matching or thermal tracking; suitable only for non-critical mirroring where cost > precision | Choose for cost-sensitive consumer applications where ±10% current error is acceptable |
Compared with BCV61BE6327HTSA1, BCV62B enables complementary biasing but requires circuit redesign, while MBT3904DW1T1G sacrifices matching and thermal stability for lower unit cost-making BCV61B optimal for automotive-grade precision current replication.

FAQ
What is the maximum continuous collector current per transistor in BCV61BE6327HTSA1?
The absolute maximum DC collector current per transistor is 100 mA at TS = 99 °C, with peak pulsed current up to 200 mA for tp < 10 ms. Derating is required above 99 °C ambient or board temperature, per the Ptot vs. TS curve in Figure 5 of the datasheet.
Can BCV61BE6327HTSA1 be used in a Wilson current mirror configuration?
Yes - its matched VBE, low VCE(sat), and monolithic thermal coupling make it ideal for Wilson mirrors. Pin 3 (E1) connects to the base of T2 (Pin 1/C2), while Pin 4 (E2) serves as the output emitter node, enabling <0.1% mirror ratio error at 25 °C.
Is BCV61BE6327HTSA1 compatible with lead-free reflow soldering profiles?
Yes - it uses matte tin-plated leads and is qualified for standard Pb-free reflow per JEDEC J-STD-020, with peak temperature tolerance up to 260 °C for 10 seconds. The SOT-143 package has been validated for compatibility with IPC-A-610 Class 2 and Class 3 assembly requirements.
How does the IC1/IC2 matching performance change at elevated temperature?
At 150 °C junction temperature, the IC1/IC2 ratio remains within 0.7–1.3 at IE2 = 0.5 mA, identical to room-temperature spec - confirming that monolithic integration preserves matching under thermal stress, unlike discrete dual-transistor solutions which degrade beyond 85 °C.
