Product details
Overview
BAT54GWX from Nexperia is a planar Schottky barrier diode with integrated guard ring for stress protection, housed in an SOD123 surface-mount package. It delivers 30 V reverse voltage rating, 200 mA continuous forward current, ≤400 mV forward voltage at 10 mA, ≤2 µA reverse leakage at 25 V, and 10 pF capacitance at 1 V - enabling ultra-high-speed switching in automotive signal conditioning circuits.
For engineers reviewing the BAT54GWX datasheet, BAT54GWX pinout, BAT54GWX application, or BAT54GWX equivalent, this page provides verified electrical parameters, thermal resistance values (Rth(j-a) = 350 K/W on FR4), AEC-Q101 qualification status, and real-world use context for line termination and high-frequency clamping in automotive ECUs and sensor interfaces.
Technical Context
The BAT54GWX employs a planar Schottky junction architecture with an integrated guard ring to suppress edge breakdown and improve surge robustness under transient stress. Its low-barrier metal-semiconductor interface enables fast carrier injection and minimal minority-carrier storage, supporting sub-nanosecond recovery times.
Designed for operation up to 150 °C junction temperature, it maintains stable VF and IR across −55 °C to +150 °C ambient range. Thermal performance is characterized for two mounting conditions: standard footprint (Rth(j-a) = 350 K/W) and enhanced cathode pad (Rth(j-sp) = 58 K/W), enabling accurate thermal design in space-constrained automotive PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - defines maximum DC or repetitive peak reverse bias before breakdown; suitable for 24 V automotive bus clamping. |
| Forward Current (IF) | 200 mA continuous - supports signal-level rectification and steering in low-power logic interfaces without derating at 25 °C. |
| Forward Voltage (VF) | ≤400 mV at IF = 10 mA - minimizes conduction loss in high-frequency switching paths, reducing self-heating in dense layouts. |
| Reverse Leakage (IR) | ≤2 µA at VR = 25 V - ensures low standby power draw in always-on automotive modules such as CAN wake-up receivers. |
| Capacitance (Cd) | 10 pF at VR = 1 V, f = 1 MHz - enables clean signal integrity in >100 MHz line termination applications without excessive loading. |
| Junction Temp (Tj) | 150 °C max - allows reliable operation in engine bay or transmission control units where ambient exceeds 105 °C. |
| AEC-Q101 Qualified | Yes - certified for automotive discrete semiconductors per stress test requirements including HTRB, HTGB, and ESD-HBM ≥2 kV. |
Pinout & Package
The BAT54GWX is packaged in the SOD123 surface-mount plastic case (3.75 × 2.55 × 1.3 mm), featuring a molded body with visible cathode marking bar. The compact outline supports high-density routing on double-sided automotive PCBs with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative terminal; marked by physical bar on package; connects to ground or lower-potential node in clamping/steering configurations. |
| 2 | Anode (A) | Positive terminal; accepts input signal or supply rail; forms forward-biased path when voltage at A exceeds K by ≥0.3 V. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Prevents premature edge breakdown under voltage transients, improving reliability in ISO 7637-2 pulse-loaded automotive lines. |
| Low VF / low IR trade-off | Optimized Schottky metallization achieves 400 mV VF at 10 mA while holding IR ≤2 µA - critical for low-power sensor bias networks. |
| Small SOD123 footprint | Occupies only 9.6 mm² board area with 2.36 mm pad length - fits between fine-pitch connectors in ADAS camera modules. |
| Thermal resistance control | Rth(j-sp) = 58 K/W to cathode solder point enables direct thermal coupling to copper pour, reducing ΔT by >40 % vs. standard layout. |
Applications
| Automotive CAN Bus Protection | USB 2.0 Data Line Clamping |
|---|---|
Use Scenario: Placed across CAN_H/CAN_L differential pair to clamp ESD and load-dump transients in body control modules. IC Role / Device Role: Bidirectional transient voltage suppressor leveraging low capacitance and fast response of Schottky junction. Use Value: 10 pF capacitance avoids signal rise-time degradation at 1 Mbps CAN bit rate; AEC-Q101 qualification ensures field durability. | Use Scenario: Integrated into USB 2.0 upstream port to protect host controller PHY from ±8 kV contact ESD per IEC 61000-4-2. IC Role / Device Role: Low-capacitance steering diode that shunts ESD current to ground while preserving 480 Mbps data integrity. Use Value: ≤2 µA leakage prevents false detection during suspend mode; 400 mV VF ensures minimal voltage drop on VBUS-sense paths. |
| High-Speed Logic Level Shifting | RF Signal Detector Input Protection |
Use Scenario: Used in 3.3 V ↔ 5 V level translation for SPI peripherals in infotainment head units with mixed-voltage domains. IC Role / Device Role: Passive clamping diode limiting input voltage swing to safe levels for downstream CMOS inputs. Use Value: Sub-1 ns recovery time prevents latch-up during 20+ MHz clock edges; SOD123 size allows placement within 2 mm of IC pin. | Use Scenario: Mounted at RF detector input (e.g., ADL5511) in automotive radar front-end to prevent damage from antenna coupling surges. IC Role / Device Role: Low-junction-capacitance limiter protecting sensitive logarithmic amplifier inputs from overvoltage. Use Value: 10 pF capacitance avoids detuning of 77 GHz matching networks; 30 V VR withstands induced transients from nearby power stages. |
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 NSR0230P2T5G | Same SOD-123 package; VF = 450 mV @ 10 mA; IR = 5 µA @ 25 V; not AEC-Q101 qualified. | Lacks automotive qualification; higher leakage limits use in always-on battery monitoring circuits. | Select when cost sensitivity outweighs AEC-Q101 requirement and leakage <2 µA is not mandatory. |
| Vishay SD103AW-G | SOD-123 package; VF = 470 mV @ 10 mA; VR = 40 V; IR = 10 µA @ 25 V; AEC-Q101 qualified. | Higher VR enables 36 V truck systems; higher IR and VF reduce efficiency in low-voltage sensor bias rails. | Choose for 24 V commercial vehicle designs needing >30 V margin, accepting higher conduction loss. |
Compared with NSR0230P2T5G and SD103AW-G, the BAT54GWX uniquely balances AEC-Q101 compliance, 2 µA leakage, and 400 mV VF - making it optimal for low-power, high-reliability automotive signal conditioning where thermal and ESD margins are tightly constrained.

FAQ
Is BAT54GWX suitable for bidirectional ESD protection?
No - the BAT54GWX is a unidirectional Schottky diode with anode and cathode terminals. For bidirectional ESD protection, a dual-diode array like PESD5V0S1BA must be used. BAT54GWX functions only in forward conduction or reverse blocking mode, not symmetrical clamping.
What is the maximum allowable soldering temperature profile for BAT54GWX?
The BAT54GWX follows JEDEC J-STD-020D.2 for SOD123 packages: peak reflow temperature is 260 °C for ≤30 seconds, with ramp-up ≤3 °C/s and ramp-down ≤6 °C/s. Preheat (150–200 °C) must last 60–120 seconds to avoid thermal shock to the die attach.
Does BAT54GWX support reverse polarity protection in 12 V automotive systems?
Yes - configured as a high-side series diode, it blocks reverse battery connection up to 30 V. However, its 200 mA IF rating limits use to low-current subsystems (e.g., microcontroller reset circuits); for >500 mA loads, a MOSFET-based solution is recommended due to conduction loss.
How does the guard ring affect layout requirements for BAT54GWX?
The integrated guard ring requires no special layout but mandates adherence to Nexperia's SOD123 footprint: 2.36 mm anode pad length, 4.18 mm cathode pad length, and ≥0.81 mm solder mask clearance. Deviations risk compromising edge breakdown immunity during load-dump testing per ISO 7637-2 Pulse 5a.
