Product details

Overview

BSP62E6327HTSA1 from Infineon Technologies is a PNP silicon Darlington transistor in SOT-223 package, rated for 80 V V_CEO, 1 A continuous collector current, and 1.5 W total power dissipation at T_S ≤ 124 °C. It delivers low V_CE(sat) (1.8 V @ I_C = 1 A, I_B = 1 mA) and high DC current gain (h_FE ≥ 1000 @ I_C = 150 mA), enabling efficient high-gain switching in automotive load control circuits.

For engineers reviewing the BSP62E6327HTSA1 datasheet, BSP62E6327HTSA1 pinout, BSP62E6327HTSA1 application, or BSP62E6327HTSA1 equivalent, key selection criteria include verified V_CEO/V_CBO ratings, Darlington saturation voltage under specified drive conditions, thermal resistance R_thJS ≤ 17 K/W, and AEC-Q101 qualification status for automotive-grade reliability.

Technical Context

This device implements a two-stage PNP Darlington configuration to achieve high current gain while maintaining single-package integration. Its structure supports direct base-driven switching without external bias networks, with guaranteed V_CE(sat) ≤ 1.8 V at full-rated 1 A collector current and 1 mA base drive.

Thermal design relies on the SOT-223 package's low junction-to-soldering-point resistance (R_thJS ≤ 17 K/W), enabling stable operation up to 150 °C junction temperature. The device is qualified per AEC-Q101 for automotive applications requiring robustness against thermal cycling and humidity exposure.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	80 V - Maximum allowable collector-emitter voltage before breakdown under open-base condition; defines safe operating voltage margin in 24 V automotive loads.
I_C (continuous)	1 A - Continuous collector current rating at T_S ≤ 124 °C; supports driving solenoids, relays, and LED arrays without forced cooling.
V_CE(sat)	1.8 V @ I_C = 1 A, I_B = 1 mA - Confirmed saturation voltage under full-load drive; determines conduction loss and self-heating in switched-mode operation.
h_FE	≥1000 @ I_C = 150 mA, V_CE = 10 V - Minimum DC current gain ensures reliable turn-on with microcontroller GPIO-level base drive (e.g., 3.3 V/5 V logic).
R_thJS	≤17 K/W - Junction-to-soldering-point thermal resistance; enables PCB copper area design for thermal management without heatsinks in moderate-power applications.
AEC-Q101	Qualified - Certified for automotive electronic systems per stress test requirements including HTOL, TC, HAST, and ESD; required for under-hood and body-control modules.

Pinout & Package

SOT-223 package with exposed thermal pad (pin 4), standardized footprint per Infineon outline drawing: 6.5 mm × 3.5 mm × 1.8 mm height, 1.6 mm pin pitch, and 0.25 mm lead thickness. Pin 1 = Base, Pin 2 = Collector, Pin 3 = Emitter, Pin 4 = Collector (thermal tab).

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Base	Control input node; accepts low-current drive (≤100 mA) to switch high collector current via Darlington action.

Pin 3	Emitter	Reference terminal for load connection; common return path for collector current and base drive loop.
Pin 4	Collector (thermal tab)	Exposed copper pad soldered to PCB ground plane; primary thermal path for heat dissipation (R_thJS ≤ 17 K/W).

Key Features

Feature	Design Value

Use Value: Maintains relay hold current with <2.2 V V_BE(sat) at 1 mA drive, enabling compatibility with 3.3 V logic controllers without level-shifting circuitry.

LED Array Power Switch

Heater Element Controller

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP Darlington switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BCP53-16	V_CEO = 45 V, h_FE ≥ 250 @ I_C = 150 mA - Lower voltage rating and reduced gain vs. BSP62.	Restricted to 12 V systems only; unsuitable for 24 V commercial vehicle loads due to insufficient V_CEO margin.	Select when cost sensitivity outweighs voltage headroom needs in low-voltage consumer electronics.
MMBT6427	V_CEO = 80 V, but single PNP (not Darlington); h_FE = 60–120 - Requires higher base drive current (≥10 mA) for same collector current.	Needs external base resistor network and may require logic-level buffer for MCU compatibility.	Choose where faster switching speed (f_T > 100 MHz) is prioritized over drive simplicity and saturation loss.

Compared with BCP53-16 and MMBT6427, BSP62E6327HTSA1 uniquely combines AEC-Q101 qualification, 80 V V_CEO, and Darlington-level gain in one SOT-223 package-enabling single-device, MCU-direct, automotive-grade switching without support components.

FAQ

What is the maximum allowable base current for BSP62E6327HTSA1?

The absolute maximum base current is 100 mA, as specified in the "Maximum Ratings" table. Exceeding this value risks permanent damage to the base-emitter junction. For reliable operation at I_C = 1 A, the recommended base drive is 1 mA-well within safe limits and sufficient due to Darlington gain.

Can BSP62E6327HTSA1 be used in high-frequency PWM applications?

Its transition frequency f_T is rated at 200 MHz under test conditions (I_C = 100 mA, V_CE = 5 V), but practical switching speed is limited by stored charge and Darlington architecture. Turn-off time t_s is typically <1 µs, making it suitable for PWM up to ~50 kHz-not RF or Class-D audio frequencies.

Is the SOT-223 thermal pad (Pin 4) required to be soldered to PCB ground?

Yes-Pin 4 is electrically connected to the collector and serves as the primary thermal path. To achieve the specified R_thJS ≤ 17 K/W, the pad must be fully soldered to a minimum 100 mm² copper pour with ≥2 thermal vias to inner ground planes. Omitting this compromises thermal performance and derates power handling.

Does BSP62E6327HTSA1 support reverse-battery protection in automotive designs?

No-it is a PNP Darlington transistor, not a dedicated protection device. While its V_CBO = 90 V provides some margin, it lacks integrated reverse-polarity blocking. External diodes or MOSFET-based protection circuits remain necessary for true reverse-battery tolerance in 12/24 V vehicle systems.
