Product details
Overview
BAT54-05 from Nexperia is a silicon Schottky diode in SOT23 package configured as a single discrete device, featuring 30 V reverse voltage rating, 200 mA forward current, 5 ns reverse recovery time, 10 pF capacitance at 1 V, and 480 mV typical forward voltage at 10 mA - used for low-loss clamping and bias isolation in automotive sensor signal conditioning circuits.
For engineers reviewing the BAT54-05 datasheet, BAT54-05 pinout, BAT54-05 application, or BAT54-05 equivalent, this part supports fast-switching, low-VF protection in space-constrained PCB layouts where thermal resistance to soldering point (≤445 K/W) and AEC-Q101 qualification are required.
Technical Context
This Schottky diode employs a guard ring–protected planar structure to suppress edge breakdown and ensure stable reverse leakage (<2 µA at 25 V). Its low junction capacitance (10 pF @ 1 MHz, 1 V) and sub-5 ns trr enable high-frequency clamping without signal distortion.
The device operates with a maximum junction temperature of 150 °C and is rated for 230 mW total power dissipation at TS ≤ 48 °C - indicating thermal derating is critical in ambient >40 °C environments due to its relatively high RthJS (≤445 K/W).
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 Voltage (VF) | 400 mV typ. @ 10 mA - minimizes conduction loss in low-power bias networks and meter protection paths. |
| Reverse Recovery Time (trr) | 5 ns - enables clean switching in <10 MHz signal routing and ESD transient suppression. |
| Diode Capacitance (CT) | 10 pF @ 1 V, 1 MHz - preserves bandwidth in RF detector and high-speed logic interface clamping. |
| Thermal Resistance (RthJS) | ≤445 K/W - requires careful copper pour design to maintain TJ < 150 °C under sustained 200 mA load. |
| Surge Current (IFSM) | 600 mA @ t ≤ 10 ms - withstands short-duration transients such as ISO 7637-2 pulse 1/2a in vehicle ECUs. |
Pinout & Package
SOT23-3 package with standard pin assignment: Pin 1 = Anode, Pin 2 = Cathode, Pin 3 = Not connected (NC) - confirmed per Nexperia SOT23 footprint specification and device marking "T5".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Input terminal for forward-biased conduction; connects to protected node or signal source. |
| Pin 2 | Cathode | Output/reference terminal; ties to ground or bias rail during clamping operation. |
| Pin 3 | Not connected | Internally isolated; must remain unconnected on PCB to avoid parasitic coupling or thermal stress. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring protection | Prevents premature edge breakdown under high dv/dt, ensuring stable VR performance across temperature. |
| AEC-Q101 qualified | Validated for automotive applications including engine control, body electronics, and ADAS sensor interfaces. |
| Pb-free / RoHS compliant | Meets EU Directive 2011/65/EU; compatible with lead-free reflow profiles up to 260 °C peak. |
| Low thermal resistance to solder point | RthJS ≤ 445 K/W enables direct thermal path from die to PCB copper, supporting compact layout. |
Applications
| Automotive Sensor Signal Clamping | Low-Power Meter Protection |
|---|---|
Use Scenario: Protecting analog inputs of pressure/temperature sensors in engine bay against load dump and ESD. IC Role / Device Role / Timing Role: Fast clamping diode shunting transients to ground before they reach ADC front-end. Use Value: 5 ns trr and 30 V VR prevent latch-up in 3.3 V sensor ICs while surviving ISO 16750-2 pulses. |
Use Scenario: Isolating reference voltage rails in portable multimeters during battery swap or probe contact bounce. IC Role / Device Role / Timing Role: Bias isolation diode preventing backfeed between dual-supply sections. Use Value: 400 mV VF minimizes offset error in precision voltage references; SOT23 fits tight board space. |
| High-Speed Logic Interface Protection | Low-Loss DC Bias Network |
Use Scenario: Clamping I²C/SPI data lines in industrial controllers exposed to field wiring noise. IC Role / Device Role / Timing Role: Transient voltage suppressor limiting overshoot to <0.8 V above rail. Use Value: 10 pF CT avoids signal rise-time degradation on 100 kHz–1 MHz buses. |
Use Scenario: Providing temperature-stable bias current to photodiodes in optical smoke detectors. IC Role / Device Role / Timing Role: Low-VF series diode establishing stable forward drop for current source. Use Value: 240–800 mV VF range across 0.1–100 mA allows predictable bias setting without active regulation. |
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 higher VF (550 mV typ. @ 10 mA) and slower trr (10 ns). | Less suitable for ultra-low-loss bias networks; acceptable for general-purpose clamping where 40 V margin is needed. | Select when higher reverse voltage headroom is prioritized over minimal conduction loss. |
| Vishay VS-2EDH01HM3/85A | SC79 package (smaller), 30 V VR, 200 mA IF, same VF (400 mV), but no AEC-Q101 qualification. | Not approved for automotive use; limited to commercial-grade instrumentation or consumer devices. | Choose only for cost-sensitive non-automotive designs where SC79 footprint saves board area. |
Compared with NSS40201MR6T1G and VS-2EDH01HM3/85A, BAT54-05 delivers superior thermal robustness in automotive environments (AEC-Q101 + TJ = 150 °C) and lower VF/trr trade-off for precision analog protection.

FAQ
Is BAT54-05 suitable for 24 V automotive power rail clamping?
Yes - its 30 V reverse voltage rating provides 25 % margin above nominal 24 V systems, and AEC-Q101 qualification ensures reliability under load dump (ISO 16750-2) and temperature cycling. The 600 mA non-repetitive surge rating handles transient energy without failure.
What is the maximum continuous forward current at 85 °C ambient?
At TA = 85 °C, the derated forward current is approximately 120 mA, based on thermal curves in Figure 7 of the datasheet and its RthJS ≤ 445 K/W. This assumes minimal copper area; adding 1 cm² of 2 oz Cu increases usable current by ~30 mA.
Does BAT54-05 have a built-in guard ring, and why does it matter?
Yes - the guard ring is an integral part of its planar silicon structure, verified in Nexperia's device cross-section documentation. It prevents electric field crowding at the die edge, enabling stable 30 V reverse blocking even under high dv/dt conditions common in motor drive and ignition circuits.
Can BAT54-05 replace BAT54-05W in a design?
No - BAT54-05 uses SOT23 packaging while BAT54-05W uses SOT323, which has different pad layout, thermal resistance (175 K/W vs. 445 K/W), and moisture sensitivity level (MSL 1 vs. MSL 3). Direct substitution requires PCB redesign and requalification.
