Product details
Overview
BAT54CM from Nexperia is a dual Schottky barrier diode in a leadless DFN1006-3 (SOT883) package, configured with two anodes and a common cathode. It delivers 30 V reverse voltage rating, 200 mA forward current per diode, 240 mV forward voltage at 0.1 mA, and 10 pF capacitance at 1 V - enabling ultra-high-speed switching and low-loss clamping in space-constrained portable electronics.
For engineers reviewing the BAT54CM datasheet, BAT54CM pinout, BAT54CM application, or BAT54CM equivalent, key selection criteria include its common-cathode dual-diode topology, AEC-Q101 qualification for automotive environments, 1.17 mm² board area, and thermal resistance of 500 K/W on FR4 PCB - all critical for ESD protection, rail clamping, and signal routing in mobile cameras and PCMCIA interfaces.
Technical Context
The BAT54CM integrates two independent Schottky diodes sharing a single cathode terminal, supporting parallel clamping or dual-rail protection without inter-diode coupling. Its planar construction and low-junction-capacitance (10 pF @ 1 V) enable sub-nanosecond switching response and minimal signal distortion in high-frequency digital I/O paths.
Designed for operation up to 150 °C junction temperature and qualified to AEC-Q101, it sustains repetitive peak forward current of 300 mA and non-repetitive surges up to 600 mA - making it suitable for transient suppression in automotive infotainment power rails and USB data line protection where thermal margin and reliability are tightly constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V max - defines maximum allowable DC or steady-state reverse bias before breakdown; sets clamping ceiling in overvoltage protection circuits. |
| Forward Current (IF) | 200 mA continuous per diode - supports sustained current handling in level-shifting or biasing applications without thermal runaway. |
| Forward Voltage (VF) | 240 mV at 0.1 mA - enables ultra-low-loss signal steering and logic-level clamping with minimal voltage drop at low drive currents. |
| Diode Capacitance (Cd) | 10 pF at 1 V, 1 MHz - ensures minimal loading on high-speed data lines (e.g., SDIO, USB 2.0) and preserves signal integrity. |
| Thermal Resistance (Rth(j-a)) | 500 K/W on FR4 - determines junction-to-ambient temperature rise under 250 mW total dissipation; guides PCB copper layout for thermal management. |
| Package Size | 1.0 × 0.6 × 0.48 mm - occupies only 1.17 mm² board area, reducing footprint by ~90% vs. SOT23 while maintaining comparable power dissipation. |
Pinout & Package
Encapsulated in a leadless DFN1006-3 (SOT883) plastic package measuring 1.0 mm × 0.6 mm × 0.48 mm with 0.35 mm pitch, the BAT54CM uses a bottom-terminated 3-terminal layout optimized for reflow soldering on fine-pitch PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Anode of Diode 1 | Input node for first Schottky path; connects to protected signal or supply rail requiring clamping to common cathode. |
| 2 (A2) | Anode of Diode 2 | Independent input node for second Schottky path; enables dual-rail protection or bidirectional signal conditioning. |
| 3 (CC) | Common Cathode | Shared output node tied to reference potential (e.g., VCC or GND); establishes unified clamping threshold for both diodes. |
Key Features
| Feature | Design Value |
|---|---|
| Low Forward Voltage | 240 mV at 0.1 mA - minimizes conduction loss and improves efficiency in low-power signal routing and battery-sensitive designs. |
| AEC-Q101 Qualification | Stress-tested for automotive discrete semiconductors - validates reliability for under-hood and infotainment applications without derating. |
| Ultra-Small Footprint | 1.17 mm² board area - allows placement near BGA or fine-pitch connectors where SOT23 is mechanically incompatible. |
| Common-Cathode Dual Configuration | Single CC terminal simplifies PCB routing and reduces net count versus discrete dual-diode solutions - cuts assembly cost and layout complexity. |
Applications
| Mobile Camera Interface Protection | Digital Still Camera Power Rail Clamping |
|---|---|
Use Scenario: Protecting MIPI CSI-2 data lanes from ESD and voltage transients during hot-plug insertion in smartphone camera modules. IC Role / Device Role / Timing Role: Dual Schottky clamp with common cathode referenced to VDDIO, providing bidirectional low-capacitance surge shunting. Use Value: 10 pF capacitance prevents signal degradation at >500 Mbps data rates, while 240 mV VF ensures minimal impact on logic-high margin. |
Use Scenario: Clamping 3.3 V power rails against load-dump spikes and inductive kickback in compact digital still cameras. IC Role / Device Role / Timing Role: Common-cathode dual diode connected between VDD and VDDIO rails to clamp cross-rail overvoltage events. Use Value: 30 V VR rating accommodates transient excursions beyond nominal rail voltage, and 200 mA IF supports sustained clamp current during fault conditions. |
| PCMCIA Card Signal Line Protection | Automotive Infotainment USB Data Lines |
Use Scenario: Guarding 16-bit parallel interface signals (e.g., OE#, CE#) against ESD in legacy PCMCIA memory cards. IC Role / Device Role / Timing Role: Low-VF Schottky pair routing transients from each signal line to shared ground or VCC rail via common cathode. Use Value: 1.0 × 0.6 mm package fits within tight card-edge spacing; 500 K/W Rth(j-a) allows safe operation at ambient temperatures up to 85 °C. |
Use Scenario: Protecting USB 2.0 D+ and D− lines in automotive head units exposed to ISO 10605 ESD pulses and load-dump noise. IC Role / Device Role / Timing Role: Dual-anode configuration routes D+ and D− transients to common cathode tied to VBUS or chassis ground. Use Value: AEC-Q101 qualification confirms robustness across -40 °C to +125 °C operating range, and 2 µA IR at 25 V ensures negligible standby leakage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR20F30NXT5G | Higher VF (370 mV @ 1 mA), same 30 V VR, larger SOD-923 package (1.7 × 0.9 mm). | Larger footprint limits use in ultra-dense layouts; higher VF increases conduction loss in low-current bias networks. | Select when higher surge current rating (IFSM = 1 A) is required and board space permits. |
| Vishay VS-2EDH01HM3/85A | Lower VR (20 V), higher IF (350 mA), SC-79 package (1.3 × 0.85 mm), no AEC-Q101 qualification. | Not rated for automotive use; insufficient VR headroom for 3.3 V rail clamping with margin. | Prefer for cost-sensitive industrial USB ports where AEC-Q101 is unnecessary and 20 V VR suffices. |
Compared with NSR20F30NXT5G and VS-2EDH01HM3/85A, the BAT54CM uniquely balances ultra-small size (1.0 × 0.6 mm), AEC-Q101 compliance, and 30 V VR - making it optimal for automotive-grade, space-constrained clamping where low VF and low Cd are mandatory.

FAQ
What is the thermal resistance of BAT54CM on a standard FR4 PCB?
The BAT54CM has a junction-to-ambient thermal resistance (Rth(j-a)) of 500 K/W when mounted on a standard FR4 PCB with 60 µm single-sided copper, tin-plated, and using the recommended footprint. This value assumes free-air convection and is measured per the IEC 60134 absolute maximum rating system. Derating is required above 25 °C ambient to maintain Tj ≤ 150 °C.
Is BAT54CM suitable for USB 2.0 data line protection?
Yes - its 10 pF diode capacitance at 1 V and 240 mV forward voltage at 0.1 mA minimize signal distortion and timing skew on D+ and D− lines. The common-cathode configuration allows symmetrical clamping to VBUS or ground, and AEC-Q101 qualification ensures robustness against automotive-grade ESD (IEC 61000-4-2 Level 4) and electrical fast transients.
How does the common-cathode configuration affect circuit design?
The common-cathode (CC) pin requires connection to a stable reference - typically VCC or GND - enabling simultaneous clamping of two independent anode signals to that rail. This eliminates need for separate cathode traces, reduces net count, and avoids mismatched forward voltage drops that occur with discrete dual-diode implementations. Layout must ensure low-inductance CC connection for effective transient shunting.
What is the marking code for BAT54CM on the device body?
The BAT54CM is marked with the code "S3" on its top surface, visible under magnification. This 2-character laser marking conforms to Nexperia's standard DFN1006-3 identification scheme and is verified per Table 4 of the official product data sheet dated 28 April 2025. No additional date or lot codes appear on the device itself.
