Product details
Overview
BAT 54-02V E6327 from Infineon Technologies is a silicon Schottky diode in SOT23 package configured as a single discrete device, with 30 V reverse voltage rating, 200 mA forward current, 5 ns reverse recovery time, 10 pF capacitance at 1 V, and 240–800 mV forward voltage across 0.1–100 mA range - used for low-loss clamping and bias isolation in automotive sensor signal conditioning circuits.
For engineers reviewing the BAT 54-02V E6327 datasheet, BAT 54-02V E6327 pinout, BAT 54-02V E6327 application, or BAT 54-02V E6327 equivalent, key selection criteria include its AEC-Q101 qualification, low VF at microamp bias, fast trr for high-frequency switching, and thermal derating behavior up to 126 °C junction temperature.
Technical Context
This Schottky diode employs a guard ring protected silicon junction to suppress edge breakdown and ensure stable reverse leakage under transient stress. Its low forward voltage drop (240 mV at 0.1 mA) enables accurate bias point setting in low-current analog front-ends.
The 5 ns reverse recovery time and 10 pF junction capacitance support operation in >10 MHz signal path clamping and RF detector applications, while its SOT23 package provides standardized pick-and-place compatibility and thermal resistance of ≤105 K/W (junction-to-soldering point).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - supports rail-to-rail clamping on 24 V automotive supply lines without breakdown |
| Forward Current (IF) | 200 mA - sufficient for continuous bias current in sensor interface and protection circuits |
| Reverse Recovery Time (trr) | 5 ns - enables use in >10 MHz signal routing and fast transient suppression |
| Junction Capacitance (CT) | 10 pF at 1 V - minimizes loading on high-impedance sensor outputs and RF nodes |
| Forward Voltage (VF) | 240 mV @ 0.1 mA - preserves accuracy in µA-level bias networks and precision reference paths |
| Thermal Resistance (RthJS) | ≤105 K/W - allows sustained 200 mA operation up to 126 °C case temperature in constrained PCB layouts |
| Junction Temperature (Tj) | 150 °C - rated for under-hood automotive environments per AEC-Q101 stress testing |
Pinout & Package
SOT23 package: surface-mount, 3-terminal plastic case with standard footprint (2.9 × 1.3 × 1.0 mm), lead-free (RoHS-compliant), and qualified to AEC-Q101 for automotive reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Current entry node | Connected to higher-potential side in clamping or bias isolation configurations |
| Cathode (Pin 2) | Current exit node | Typically tied to ground or reference rail; defines polarity-sensitive protection direction |
| NC / Heat Sink (Pin 3) | Non-connected / thermal pad | Not electrically connected; serves as mechanical anchor and minor thermal path in PCB layout |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring protection | Prevents premature edge breakdown under high dv/dt or localized thermal stress |
| AEC-Q101 qualification | Validated for automotive electronics including engine control, body modules, and ADAS sensors |
| Low VF at sub-mA bias | 240 mV @ 0.1 mA enables stable biasing in ultra-low-power analog monitoring circuits |
| Fast trr with low CT | 5 ns recovery + 10 pF capacitance supports clean signal integrity in 10–100 MHz clamping applications |
| Pb-free RoHS compliance | Meets EU Directive 2011/65/EU and automotive ELV requirements for hazardous substance restriction |
Applications
| Automotive Sensor Signal Clamping | Low-Power Bias Isolation |
|---|---|
Use Scenario: Protecting analog inputs of engine knock sensors from ESD and load dump transients in 12 V vehicle systems. IC Role / Device Role / Timing Role: Discrete Schottky clamp placed between sensor output and ADC input, conducting only during overvoltage events. Use Value: 30 V VR withstands ISO 7637-2 Pulse 5a (load dump), while 5 ns trr prevents signal distortion during fast transients. | Use Scenario: Isolating bias current paths in battery-powered tire pressure monitoring system (TPMS) RF receivers. IC Role / Device Role / Timing Role: Single Schottky diode blocking reverse leakage between LDO output and RF amplifier bias node. Use Value: 240 mV VF at 0.1 mA ensures minimal voltage drop and no measurable impact on µA-level sleep-mode current budget. |
| High-Frequency Detector Diode | Low-Loss Meter Protection |
Use Scenario: Demodulating 27 MHz ASK signals in keyless entry receiver front-ends. IC Role / Device Role / Timing Role: Passive envelope detector where low CT and fast trr preserve modulation fidelity. Use Value: 10 pF CT minimizes RF shunting loss; 5 ns trr avoids distortion of narrow pulse envelopes. | Use Scenario: Input protection for handheld multimeter analog front-end ICs exposed to accidental 100 V DC probe misapplication. IC Role / Device Role / Timing Role: Series-connected Schottky limiting current into sensitive op-amp inputs during overvoltage faults. Use Value: 200 mA IF rating and 30 V VR allow safe dissipation of 2 W fault energy (100 V × 20 mA) without latch-up or parametric shift. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS40201MR6T1G | Same SOT23 package, 40 V VR, 200 mA IF, but VF = 370 mV @ 10 mA (vs. 400 mV for BAT54-02V) | Higher VR margin suits 36 V industrial systems; less suitable for µA-bias analog nodes due to higher VF | Select when higher reverse margin outweighs low-bias VF sensitivity |
| Vishay SMBT3904LT1G (Schottky variant: SMBT3904S) | SC70 package, 30 V VR, 200 mA IF, VF = 280 mV @ 1 mA, trr = 6 ns | Smaller footprint (2.0 × 1.25 mm) but higher RthJA; not AEC-Q101 qualified | Select for space-constrained consumer designs where automotive qualification is unnecessary |
Compared with NSS40201MR6T1G and SMBT3904S, BAT 54-02V E6327 uniquely balances AEC-Q101 compliance, sub-300 mV VF at 0.1 mA, and 5 ns trr - making it optimal for automotive sensor interfaces requiring both precision biasing and fast transient response.

FAQ
Is BAT 54-02V E6327 pin-compatible with BAT54 or BAT54W?
No - BAT 54-02V E6327 is a single-diode SOT23 device with anode-cathode-NC pinout (Pin 1 = Anode, Pin 2 = Cathode, Pin 3 = NC). BAT54W is a dual common-cathode configuration in SOT323, and standard BAT54 is single-diode in SOT23 but uses different marking and thermal specs. Physical pin alignment does not imply functional or electrical interchangeability.
What is the maximum allowable soldering temperature for BAT 54-02V E6327?
The peak reflow temperature is 260 °C for 10 seconds max, per JEDEC J-STD-020. The device uses Pb-free terminations compatible with standard lead-free reflow profiles. Hand-soldering must not exceed 350 °C for <3 seconds per terminal to avoid delamination or junction damage.
Does BAT 54-02V E6327 support bidirectional ESD protection?
No - it is a unidirectional Schottky diode. For bidirectional ESD protection, a paired BAT54-02V with reversed orientation or a dedicated TVS array (e.g., Infineon ESD204-B1-02EL) is required. Its guard ring design enhances unidirectional surge handling but does not provide symmetrical clamping.
How does junction temperature derating affect forward current in BAT 54-02V E6327?
At 126 °C case temperature, the absolute maximum forward current drops to 200 mA. Derating begins above 25 °C ambient: at 85 °C case, IFmax ≈ 160 mA; at 105 °C, ≈ 120 mA. This follows the published IF vs. TS curve (Document 2011-06-29, Fig. 6), where thermal resistance limits conduction capability before junction failure.
