Product details
Overview
BC856SH6327XTSA1 from Infineon Technologies is a dual PNP silicon small-signal transistor array in SOT363 (SC74) package, configured as two galvanically isolated transistors with matched characteristics. It delivers VCEO = 65 V, hFE = 200–630 (at IC = 2 mA), VCE(sat) ≤ 250 mV (IC = 100 mA), and fT = 250 MHz - optimized for AF input stages and driver circuits in automotive audio amplifiers and sensor interface modules.
For engineers reviewing the BC856SH6327XTSA1 datasheet, BC856SH6327XTSA1 pinout, BC856SH6327XTSA1 application, or BC856SH6327XTSA1 equivalent, key selection criteria include dual-PNP matching tolerance, AEC-Q101 qualification, low VCE(sat) at high IC, thermal resistance RthJS ≤ 140 K/W, and RoHS-compliant lead-free packaging.
Technical Context
This device integrates two discrete PNP transistors on a single die with electrical isolation between collector-emitter paths, enabling independent biasing while maintaining tight parameter matching (e.g., hFE, VBE(sat)). Its design supports linear amplification and switching in compact dual-channel configurations without cross-talk.
The BC856SH6327XTSA1 operates across –65 °C to +150 °C junction temperature, with guaranteed performance at TA = 25 °C per JEDEC JESD22-A108. It meets AEC-Q101 stress test requirements for automotive-grade reliability, including HTOL, temperature cycling, and HAST.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 65 V - supports rail-to-rail operation in 48 V automotive subsystems and industrial 24 V logic interfaces |
| hFE (min/typ/max) | 200 / 290 / 630 at IC = 2 mA - enables stable current gain across production lots for precision bias networks |
| VCE(sat) | ≤ 250 mV at IC = 100 mA, IB = 5 mA - minimizes conduction loss in active-load switching applications |
| fT | 250 MHz - sufficient for audio-frequency amplification up to 20 kHz with margin for harmonic content |
| RthJS | ≤ 140 K/W - allows 250 mW power dissipation at TS ≤ 115 °C, supporting thermally constrained PCB layouts |
| Ccb | 1.5 pF at VCB = 10 V - limits Miller effect in high-gain common-emitter stages |
| Q1/Q2 Matching | Galvanic isolation with matched hFE, VBE(sat), and VCE(sat) - enables differential pair use without external trimming |
Pinout & Package
SOT363 (SC74) surface-mount package: 6-pin, 2.1 mm × 2.0 mm footprint, 0.95 mm pitch, 1.1 mm max height, RoHS-compliant matte tin plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (E1) | Emitter of Transistor 1 | Low-impedance current sink node; tied to local ground reference for Q1 |
| 2 (B1) | Base of Transistor 1 | Control input for Q1; requires current-limited drive due to VBE(on) ≈ 650 mV |
| 3 (C2) | Collector of Transistor 2 | High-side output node for Q2; rated for 65 V reverse blocking |
| 4 (E2) | Emitter of Transistor 2 | Independent emitter terminal; enables separate biasing from Q1 |
| 5 (B2) | Base of Transistor 2 | Isolated control path for Q2; no shared base connection with Q1 |
| 6 (C1) | Collector of Transistor 1 | Main output collector for Q1; electrically isolated from C2 per internal layout |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-PNP transistor array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC857SH6327XTSA1 | VCEO = 45 V (vs. 65 V); otherwise identical pinout, matching, and AEC-Q101 qualification | Not suitable for >45 V rail systems; acceptable in 3.3 V/5 V logic-level driver applications | Select when lower voltage rating suffices and cost optimization is prioritized |
| MBT3906DW1T1G | hFE min = 100 (vs. 200); RthJS = 170 K/W; same SOT363 package and dual-PNP topology | Higher thermal resistance limits continuous 100 mA operation; reduced gain stability at low IC | Acceptable for non-automotive, non-matching-critical uses where cost is primary constraint |
Compared with BC856SH6327XTSA1, BC857SH6327XTSA1 trades voltage headroom for identical matching and thermal performance, while MBT3906DW1T1G sacrifices gain consistency and thermal capability for broader commercial availability - making BC856S optimal for AEC-Q101–mandated 65 V dual-PNP designs.

FAQ
Is BC856SH6327XTSA1 pin-compatible with BC857SH6327XTSA1?
Yes - both share identical SOT363 (SC74) pinout: Pin 1=E1, Pin 2=B1, Pin 3=C2, Pin 4=E2, Pin 5=B2, Pin 6=C1. However, BC857S has lower VCEO (45 V vs. 65 V) and VCBO (50 V vs. 80 V), so substitution requires verification of maximum circuit voltage stress.
What is the maximum continuous collector current per transistor?
The absolute maximum continuous collector current is 100 mA per transistor at TS ≤ 115 °C. At higher ambient temperatures or with limited PCB copper area, derating applies per the Ptot vs. TS curve - e.g., 75 mA at TS = 125 °C for BC856S.
Does BC856SH6327XTSA1 support pulse operation beyond 100 mA?
Yes - peak collector current ICM is 200 mA for pulses ≤ 10 ms with duty cycle ≤ 2%. Pulse capability is validated via the Ptot(max)/Ptot(DC) vs. tp graph, showing 5× overload at tp = 100 µs with D = 0.02.
How is thermal resistance measured for this device?
RthJS = 140 K/W is defined from junction to soldering point (PCB pad center), measured per JESD51-2 with 1 cm² 2-oz copper pad. It does not represent junction-to-ambient; actual RthJA depends on board layout and airflow, and must be calculated separately using AN077 methodology.
