Product details
Overview
BAT54HGW from Nexperia is a planar Schottky barrier diode with integrated guard ring for stress protection, housed in an SOD323 surface-mount package. It delivers 30 V reverse voltage rating, 200 mA continuous forward current, 400 mV forward voltage at 10 mA, 10 pF capacitance at 1 V, and AEC-Q101 qualification - enabling use in automotive line termination and reverse polarity protection circuits.
For engineers reviewing the BAT54HGW datasheet, BAT54HGW pinout, BAT54HGW application, or BAT54HGW equivalent, key selection criteria include low VF for power-sensitive clamping, low Cd for high-speed switching integrity, AEC-Q101 compliance for automotive deployment, and SOD323 footprint compatibility with space-constrained PCB layouts.
Technical Context
This discrete Schottky diode uses a planar silicon structure with an integrated guard ring to enhance ESD and transient robustness without compromising switching speed. Its low junction capacitance (10 pF at 1 V) and fast recovery enable operation beyond 100 MHz in RF and digital line-termination roles.
The device operates across −55 °C to +125 °C ambient, with thermal resistance of 450 K/W (junction-to-ambient, FR4 single-sided copper), and supports pulsed forward currents up to 600 mA (10 ms, 25 °C initial junction temperature).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - defines maximum allowable DC or peak AC reverse bias before breakdown; critical for voltage clamping headroom |
| Forward Current (IF) | 200 mA continuous - sets steady-state power dissipation limit (≈80 mW at VF = 400 mV) |
| Forward Voltage (VF) | 400 mV at 10 mA - enables ultra-low-loss rectification and clamping in battery-powered systems |
| Diode Capacitance (Cd) | 10 pF at 1 V, 1 MHz - ensures minimal signal distortion in >100 MHz data line termination |
| Reverse Current (IR) | 2 µA at 25 V - maintains low leakage in high-impedance sensing or bias networks |
| Junction Temperature (Tj) | 125 °C max - supports under-hood automotive environments without derating at full IF |
Pinout & Package
Encapsulated in the SOD323 plastic surface-mount package (1.7 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch), the BAT54HGW features a two-terminal configuration with cathode marked by a bar on the package top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative terminal; marking bar on package identifies this pin; connects to lower-potential node in clamping or rectification paths |
| 2 | Anode (A) | Positive terminal; ties to higher-potential node; current flows from Pin 2 to Pin 1 under forward bias |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Enhances ESD robustness and transient overvoltage tolerance without increasing VF or Cd |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD22-A114 |
| Low forward voltage | 400 mV @ 10 mA enables <100 mW power loss in 3.3 V logic rail clamping |
| Low capacitance | 10 pF at 1 V minimizes signal rise-time degradation in USB 2.0 or CAN FD bus termination |
Applications
| Automotive Line Termination | USB 2.0 Data Line Clamping |
|---|---|
Use Scenario: Terminating CAN or LIN bus stubs in vehicle ECUs to suppress reflections and ringing. IC Role / Device Role / Timing Role: Passive clamping diode placed between data line and VCC/GND to absorb overshoot/undershoot transients. Use Value: 10 pF capacitance preserves signal edge integrity up to 480 Mbps; AEC-Q101 ensures 15-year under-hood reliability. |
Use Scenario: Protecting USB 2.0 D+/D− lines from ESD events during hot-plug insertion. IC Role / Device Role / Timing Role: Low-capacitance shunt path that activates only during >30 V transients, remaining transparent during normal signaling. Use Value: 400 mV VF allows clamping near 0 V without interfering with 400 mV differential signaling thresholds. |
| Reverse Polarity Protection | High-Speed Logic-Level Shifting |
Use Scenario: Preventing damage when 12 V battery leads are accidentally reversed in telematics modules. IC Role / Device Role / Timing Role: Series-connected Schottky diode in positive supply rail; blocks reverse current while minimizing dropout. Use Value: 200 mA IF rating supports typical 100–150 mA ECU subsystems; 400 mV VF limits voltage loss to <0.5% at 12 V nominal. |
Use Scenario: Level-shifting 1.8 V I²C signals to 3.3 V microcontroller interfaces in infotainment head units. IC Role / Device Role / Timing Role: Passive clamp diode tied between rails to limit voltage swing and prevent overdrive. Use Value: 10 pF Cd avoids loading 400 kHz I²C clock edges; low IR (<2 µA) prevents unintended pull-down on open-drain buses. |
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 NSR0230HT1G | Same SOD-323 package; VF = 450 mV @ 10 mA; Cd = 12 pF @ 1 V; AEC-Q101 qualified | Slightly higher VF increases conduction loss in low-voltage clamping; identical thermal and automotive specs | Prefer BAT54HGW where sub-400 mV VF is required for <3.3 V rail protection |
| Vishay VS-2EDH01HM3/85A | SOD-123 package (larger); VF = 370 mV @ 10 mA; Cd = 15 pF @ 1 V; not AEC-Q101 qualified | Higher capacitance degrades >100 MHz signal fidelity; lacks automotive qualification for ECU use | Select only for non-automotive, cost-sensitive industrial designs where board space permits larger footprint |
Compared with NSR0230HT1G and VS-2EDH01HM3/85A, the BAT54HGW uniquely balances AEC-Q101 compliance, 400 mV VF, and 10 pF capacitance in the compact SOD323 footprint - making it optimal for space- and performance-constrained automotive signal conditioning.

FAQ
Is BAT54HGW suitable for 5 V USB 2.0 data line clamping?
Yes. With 10 pF capacitance at 1 V and 400 mV forward voltage, BAT54HGW provides negligible signal loading on 480 Mbps USB 2.0 differential pairs while clamping transients above ~3.3 V. Its AEC-Q101 qualification further validates robustness against repeated ESD events encountered in automotive USB ports.
What is the thermal derating behavior above 25 °C ambient?
At 85 °C ambient, the maximum continuous forward current reduces to approximately 140 mA due to junction temperature limits (125 °C max). Derating follows linear interpolation based on Rth(j-a) = 450 K/W on FR4 single-sided copper; no additional heatsinking is effective in the SOD323 package.
Does the marking 'S0' correspond to BAT54HGW unambiguously?
Yes. Per Nexperia's official marking table, 'S0' is the unique top-side laser marking code assigned exclusively to BAT54HGW in SOD323 packaging. No other Nexperia part shares this marking in this package variant.
Can BAT54HGW replace BAT54C in existing SOD323 designs?
No. BAT54C is a dual common-cathode Schottky diode in SOT-23, whereas BAT54HGW is a single diode in SOD323. Pin count, package dimensions, and internal configuration differ fundamentally - direct replacement requires PCB layout revision and functional verification of single-diode operation.
