Product details
Overview
BAL74E6327HTSA1 from Infineon Technologies is a silicon switching diode in SOT23 package, rated for 50 V reverse voltage, 250 mA forward current, and 4 ns reverse recovery time-designed for high-speed switching in automotive signal routing and industrial sensor interface circuits.
For engineers reviewing the BAL74E6327HTSA1 datasheet, BAL74E6327HTSA1 pinout, BAL74E6327HTSA1 application, or BAL74E6327HTSA1 equivalent, key selection criteria include trr ≤ 4 ns, VF ≤ 1.0 V at IF = 100 mA, IR ≤ 0.1 µA at VR = 50 V and TA = 150 °C, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This diode operates as a fast-switching unidirectional rectifier with low junction capacitance (CT ≤ 2 pF at VR = 0 V, f = 1 MHz) and thermally robust construction (RthJS ≤ 260 K/W). Its single-diode configuration supports discrete signal path control without integrated biasing or protection circuitry.
The device meets AEC-Q101 stress test requirements for automotive use, including temperature cycling, humidity testing, and mechanical shock-enabling deployment in engine control units and body electronics where transient immunity and long-term parametric stability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 50 V - maximum DC blocking capability before breakdown |
| Reverse Recovery Time (trr) | 4 ns - enables >100 MHz switching in pulse shaping and sample-hold circuits |
| Forward Voltage (VF) | ≤1.0 V at IF = 100 mA - limits conduction loss in low-voltage logic-level signal steering |
| Junction Capacitance (CT) | ≤2 pF at VR = 0 V, f = 1 MHz - minimizes signal distortion in RF-coupled detector stages |
| Surge Forward Current (IFS) | 4.5 A for t = 1 µs - withstands ESD-induced transients per IEC 61000-4-2 Level 4 |
| Junction Temperature (Tj) | 150 °C - supports operation in under-hood automotive environments |
Pinout & Package
SOT23-3 plastic surface-mount package with gull-wing leads; standardized footprint per Infineon outline drawing EHS BCW66; pin 1 marked by dot or bevelled edge.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode) | Current entry point during forward conduction | Connected to driver output or signal source in active-low switch configurations |
| 2 (Cathode) | Current exit point during forward conduction | Tied to ground reference or pull-down node in level-shifting applications |
| 3 (Not connected) | No internal connection | Electrically isolated; must remain floating or grounded per PCB layout guidelines to avoid parasitic coupling |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive powertrain and chassis systems requiring zero-failure field performance |
| Pb-free RoHS-compliant packaging | Meets EU Directive 2011/65/EU without exemption waivers; compatible with lead-free reflow profiles |
| Low trr (4 ns) | Reduces switching losses in 1–10 MHz clock distribution and data line clamping |
| High IFS (4.5 A) | Provides single-pulse surge immunity exceeding IEC 61000-4-5 waveform 3A (1.2/50 µs) |
Applications
| Engine Control Unit Signal Clamping | Industrial CAN Bus Transceiver Protection |
|---|---|
Use Scenario: Clamps induced transients on crankshaft position sensor inputs during ignition events. IC Role / Device Role / Timing Role: Fast-switching diode placed between sensor line and ground rail to shunt ESD/EFT pulses. Use Value: 4 ns trr ensures clamping activation within first 10 ns of transient onset, preventing comparator latch-up. | Use Scenario: Protects CANH/CANL pins of transceivers against load-dump spikes in vehicle wiring harnesses. IC Role / Device Role / Timing Role: Standalone transient suppressor in series with bus lines, leveraging low CT to preserve signal integrity. Use Value: 2 pF junction capacitance avoids signal rise-time degradation beyond ISO 11898-2 specification limits. |
| Automotive LED Driver Flyback Snubber | Factory Automation Sensor Interface Isolation |
Use Scenario: Absorbs inductive kickback from solenoid-driven LED arrays in headlamp modules. IC Role / Device Role / Timing Role: Freewheeling diode across inductive load, conducting only during off-cycle energy dissipation. Use Value: 250 mA continuous rating supports 200 mA nominal LED current with 25% thermal margin at 105 °C ambient. | Use Scenario: Isolates analog outputs of pressure sensors from shared 24 V supply rails in PLC I/O modules. IC Role / Device Role / Timing Role: Reverse-polarity protection element placed upstream of LDO regulators. Use Value: 50 V VR rating covers worst-case 24 V system surges up to 48 V, with IR < 0.1 µA ensuring minimal leakage error. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAR74E6327HTSA1 | Same die, identical electrical specs; differs only in marking code and reel packaging | No functional difference; accepted interchangeably in AEC-Q101-compliant designs | Select when sourcing flexibility or dual-marking BOMs are required |
| 1N4148W-7-F | Higher VF (1.25 V typ. at 10 mA), slower trr (4 ns min., no max spec), not AEC-Q101 qualified | Suitable for commercial-grade consumer electronics but not automotive safety-critical nodes | Choose only for cost-sensitive non-automotive applications with relaxed reliability requirements |
Compared with BAR74E6327HTSA1, BAL74E6327HTSA1 offers identical performance and qualification-making it a direct marking variant-not a functional upgrade. Versus 1N4148W-7-F, it delivers guaranteed automotive reliability, tighter trr control, and lower VF at operating currents above 50 mA.

FAQ
Is BAL74E6327HTSA1 pin-compatible with BAR74E6327HTSA1?
Yes-both share identical SOT23-3 pinout, thermal profile, and electrical specifications. The only differences are part marking and reel packaging configuration; they are functionally interchangeable in all AEC-Q101-designated circuits without redesign or requalification.
What is the maximum allowable junction temperature during pulsed operation?
The absolute maximum junction temperature remains 150 °C regardless of duty cycle. For pulsed IFM = 4.5 A (t = 1 µs), peak Tj rise is calculated as ΔTj = I²·RthJS·t = (4.5)² × 260 × 10⁻⁶ ≈ 5.3 °C-well within safe margin even at 125 °C ambient.
Does this diode require external heat sinking in standard SMT layouts?
No-its RthJS ≤ 260 K/W and Ptot = 370 mW allow full-rated operation at TS ≤ 54 °C using standard 2-layer FR-4 PCBs with 1 cm² copper pour beneath the pad. Thermal vias are recommended only for sustained >200 mA operation above 85 °C ambient.
Can BAL74E6327HTSA1 replace BAT54 series diodes in USB data line protection?
No-BAT54 devices are Schottky diodes with VF ≈ 0.3 V and CT ≈ 10 pF, optimized for low-voltage bidirectional clamping. BAL74E6327HTSA1 is a PN junction diode with higher VF and lower CT, suited for unidirectional high-speed switching-not USB ESD protection.
