Product details

PNP Darlington for automotive loads

The Infineon BSP61E6327 is a PNP Darlington transistor qualified to AEC-Q101. Collector-emitter breakdown is 60 V, continuous collector current is 1 A, and DC current gain is at least 2000 at 500 mA.

Minimum hFE is 2000 at 500 mA and 10 Vce. Vce saturation is 1.8 V maximum at 1 mA base drive and 1 A collector current. Package power limit is 1.5 W.

Transition frequency and switching speed

The 200 MHz transition frequency is typical for a Darlington of this current class. It supports PWM switching up to several tens of kilohertz — adequate for lamp dimming, valve proportional control, or brushed DC motor speed control. For higher-frequency applications like switch-mode power supplies, a single PNP or MOSFET would be a better fit; the Darlington's stored charge in the output stage limits turn-off speed.

The AEC-Q101 qualification means it is released for automotive production lines and subject to the change notification and long-term supply commitments typical of that grade.

Frequently asked questions

What is the Vce of BSP61E6327?

The collector-emitter breakdown voltage is 60 V maximum. This provides adequate headroom for 12 V and 24 V automotive systems, including load-dump transients that can reach 40 V on a 12 V rail.

What is the difference between BSP61E6327 and BSP61?

The BSP61E6327 is the AEC-Q101 automotive-qualified variant of the base BSP61 PNP Darlington. The electrical ratings — 60 V Vce, 1 A Ic, hFE 2000 minimum — are identical. The E6327 suffix denotes the automotive-grade release with full production-part-approval process (PPAP) documentation available. For non-automotive applications the base BSP61 may be acceptable, but for any ECU or safety-related system the E6327 variant is the correct choice.
