Product details
Overview
BCV61BE6433HTMA1 from Infineon Technologies is an NPN silicon double transistor in SOT143 package, designed as a matched-pair current mirror with high hFE (200–420 for BCV61B), low VCE(sat) (≤200 mV at 10 mA/0.5 mA), and tight VBE matching for thermal coupling. It operates up to 150 °C and meets AEC-Q101 qualification for automotive use.
For engineers reviewing the BCV61BE6433HTMA1 datasheet, BCV61BE6433HTMA1 pinout, BCV61BE6433HTMA1 application, or BCV61BE6433HTMA1 equivalent, key selection criteria include current mirror accuracy (IC1/IC2 = 0.7–1.3 at 25 °C), dual-transistor thermal tracking, VCE rating of 30 V, and RoHS-compliant SOT143 packaging.
Technical Context
The BCV61BE6433HTMA1 integrates two monolithically matched NPN transistors on a single die to minimize thermal drift and VBE mismatch. Its design enables precise current mirroring without external emitter resistors, with guaranteed matching over temperature (IC1/IC2 = 0.7–1.3 at 150 °C) and thermal resistance RthJS ≤170 K/W.
It supports DC operation up to 100 mA per transistor and pulsed currents up to 200 mA (tp < 10 ms). The fT of 250 MHz and low Ccb (0.95 pF) support stable analog signal conditioning and bias generation in compact circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 30 V - Maximum collector-emitter voltage before breakdown; sets safe operating range for bias and switching applications. |
| hFE (T1, IC = 2 mA) | 200–420 - High DC current gain ensures low base drive requirements and stable mirror ratio under load variation. |
| VCE(sat) | ≤200 mV @ 10 mA/0.5 mA - Low saturation voltage minimizes power loss and self-heating in precision current sources. |
| IC1/IC2 Matching | 0.7–1.3 @ 25 °C - Tight current ratio tolerance enables accurate mirrored current replication without trimming. |
| RthJS | ≤170 K/W - Enables reliable thermal dissipation in confined PCB layouts with soldering-point cooling. |
| fT | 250 MHz - Supports high-frequency bias stability and small-signal amplification up to mid-VHF range. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness. |
Pinout & Package
SOT143 (4-pin plastic surface-mount package) with exposed pad thermal path; dimensions 2.9 × 1.3 × 0.9 mm; JEDEC standard footprint; RoHS-compliant matte tin lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (C2) | Collector of Transistor 2 | Output node for second mirrored current path; electrically isolated but thermally coupled to T1. |
| 2 (C1) | Collector of Transistor 1 | Primary output node for reference/mirror current; shares substrate with T2 for matched thermal response. |
| 3 (E1) | Emitter of Transistor 1 | Input node for reference current; direct connection enables unbalanced mirror configurations. |
| 4 (E2) | Emitter of Transistor 2 | Output emitter node; used with external resistor to set mirror ratio or improve matching linearity. |
Key Features
| Feature | Design Value |
|---|---|
| Monolithic matched pair | Two NPN transistors fabricated on same die for <1.3× current ratio spread and <1 K thermal gradient at steady state. |
| Low VCE(sat) | 200 mV max at 10 mA ensures <2 mW dissipation per transistor in mirror mode, reducing thermal runaway risk. |
| AEC-Q101 qualification | Validated for automotive underhood environments including 1000-hr HTOL, -40 °C to +150 °C cycling, and 8 kV HBM ESD. |
| Thermal coupling | Guaranteed ΔT < 1 K between transistors at 100 mW total dissipation, critical for temperature-stable bias networks. |
| Pb-free & RoHS | Matte tin termination compatible with lead-free reflow profiles (peak 260 °C, 10 s); no exemptions required. |
Applications
| Automotive Sensor Biasing | Current Mirror Reference |

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,115 (Nexperia) | Same SOT143 package; hFE = 160–320 (lower gain); VCE(sat) = 300 mV max - higher conduction loss. | Less suitable for low-voltage rail applications below 3.3 V due to higher saturation voltage. | Select when cost sensitivity outweighs gain and thermal performance requirements. |
| MBT3904DW1T1G (ON Semiconductor) | Higher fT (300 MHz); no guaranteed matching spec; separate die construction - ΔT up to 5 K under load. | Acceptable for non-critical biasing but not for precision current mirrors requiring <1% ratio stability. | Choose only for general-purpose dual-NPN switching where matching is not required. |
Compared with BCV61BE6433HTMA1, BCV62B offers lower cost but reduced gain and thermal tracking, while MBT3904DW1T1G provides higher speed at the expense of matched performance - making BCV61B optimal for automotive and precision analog current mirroring.

FAQ
What is the maximum continuous collector current per transistor in BCV61BE6433HTMA1?
The absolute maximum DC collector current is 100 mA per transistor at TS = 99 °C, with derating above that temperature. At ambient 25 °C with adequate PCB copper area, sustained operation up to 80 mA per device is supported without exceeding Ptot = 300 mW or Tj = 150 °C limits.
Does BCV61BE6433HTMA1 require external emitter resistors for current matching?
No - the monolithic structure provides inherent VBE matching and thermal coupling, enabling accurate current mirroring without emitter degeneration resistors. External resistors may be added only to fine-tune the mirror ratio (e.g., IC1/IC2 = 1.3) or improve linearity under high-current conditions.
Is BCV61BE6433HTMA1 pin-compatible with BCV61C variants?
Yes - all BCV61 variants (A/B/C) share identical SOT143 pinout (C2-C1-E1-E2), package dimensions, and thermal footprint. Only hFE ranges differ: BCV61B = 200–420, BCV61C = 290–520. No layout change is needed when upgrading gain grade.
Can BCV61BE6433HTMA1 be used in linear amplifier configurations?
Yes - its fT of 250 MHz, low noise figure (2 dB), and high hFE support small-signal amplification up to ~50 MHz. However, it is optimized for DC/low-frequency current mirroring; for RF amplification, dedicated RF transistors like BFP640 are recommended.
