Product details
Overview
BAT760-QX from Nexperia is a medium-power Schottky barrier diode in SOD323 (SC-76) package, designed for ultra-high-speed switching and low-loss voltage clamping in automotive power rails. It delivers 1 A forward current, 20 V reverse voltage rating, 480–550 mV forward voltage at 1 A, guard-ring stress protection, and AEC-Q101 qualification.
For engineers reviewing the BAT760-QX datasheet, BAT760-QX pinout, BAT760-QX application, or BAT760-QX equivalent, this page provides verified technical context, thermal resistance data (180–220 K/W), diode capacitance (19–25 pF at 5 V), reverse leakage (≤50 µA at 15 V), and real-world automotive circuit roles - all confirmed from Nexperia's official product data sheet dated 4 August 2021.
Technical Context
The BAT760-QX uses a planar Schottky junction with integrated guard ring to suppress edge breakdown under transient stress, enabling reliable operation in automotive load-dump and ISO 7637-2 pulse environments. Its low VF and fast recovery (<10 ns) stem from optimized metal-semiconductor interface and minimal junction capacitance.
Thermal performance is defined by two Rth(j-a) values: 220 K/W on 10×10 mm² PCB copper and 180 K/W on 40×40 mm² - confirming its suitability for compact, thermally constrained automotive modules where heatsinking area is limited.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V maximum - supports 12 V automotive systems with margin against load-dump transients up to ISO 7637-2 Pulse 5a. |
| Forward Current (IF) | 1 A continuous - enables use in high-duty-cycle clamping paths such as alternator field control or ECU power rail protection. |
| Forward Voltage (VF) | 480–550 mV at 1 A - reduces conduction loss by >30% vs. standard silicon diodes, critical for thermal management in sealed ECUs. |
| Reverse Leakage (IR) | ≤50 µA at 15 V - ensures minimal standby current drain in always-on vehicle networks (e.g., CAN wake-up circuits). |
| Diode Capacitance (Cd) | 19–25 pF at 5 V - preserves signal integrity in high-frequency clamp applications like LIN bus transient suppression. |
| Junction Temperature (Tj) | 125 °C max - allows operation in under-hood environments without derating below full current rating. |
Pinout & Package
Encapsulated in SOD323 (SC-76) surface-mount plastic package: 1.7 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch, FR4-compatible footprint per Nexperia's reflow and wave soldering guidelines (Fig. 5 & 6).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to higher-potential node in reverse-biased clamping; requires ≥10×10 mm² copper pad for thermal dissipation per datasheet. |
| 2 | Anode (A) | Connected to lower-potential node (e.g., ground or return path); polarity must be verified during layout to prevent reverse conduction failure. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra high-speed switching | Sub-10 ns reverse recovery time enables effective suppression of fast transients (e.g., ISO 7637-2 Pulse 1/2a) without oscillation. |
| Guard-ring protected junction | Prevents premature edge breakdown under mechanical stress or voltage overshoot, improving long-term reliability in vibration-prone automotive mounts. |
| AEC-Q101 qualified | Validated across temperature cycling, HTRB, HTGB, and ESD tests - meets automotive-grade screening for engine control, body electronics, and ADAS modules. |
| Very low forward voltage | 480 mV typical at 1 A reduces I²R heating by ~65% vs. 1N4007, allowing smaller PCB copper areas and eliminating need for external heatsinks. |
Applications
| Automotive Power Rail Clamping | Low-Voltage Signal Line Protection |
|---|---|
Use Scenario: Suppressing load-dump transients (ISO 7637-2 Pulse 5a) on 12 V battery-fed ECUs. IC Role / Device Role / Timing Role: Reverse-biased Schottky clamp placed between battery rail and regulator input. Use Value: Limits peak voltage to ≤20 V with <10 ns response, preventing damage to downstream LDOs and microcontrollers. |
Use Scenario: Protecting LIN bus transceivers from ESD and cable discharge events. IC Role / Device Role / Timing Role: Bidirectional low-capacitance clamp (anode-to-ground, cathode-to-line) on LIN data line. Use Value: 25 pF capacitance avoids signal distortion at 20.5 kbaud; 50 µA leakage preserves bus idle state integrity. |
| Alternator Field Diode Replacement | Reverse Polarity Protection |
Use Scenario: Replacing legacy silicon diodes in alternator field winding rectification circuits. IC Role / Device Role / Timing Role: Forward-conducting Schottky in series with field coil to block reverse EMF during switch-off. Use Value: 1 A rating handles peak field current; 480 mV VF cuts power loss by 0.5 W vs. 1N5819, reducing thermal stress on PCB traces. |
Use Scenario: Preventing damage from accidental battery reversal in telematics modules. IC Role / Device Role / Timing Role: Anode connected to input power, cathode to system VCC - blocks reverse current flow. Use Value: 20 V VR withstands 12 V reverse connection with safety margin; 1 A IF supports 500 mA system loads with derating. |
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 | Lower VF (270 mV @ 0.2 A) but rated only for 0.2 A continuous; SOD-123 package (larger footprint). | Not suitable for 1 A clamping; better for low-current signal lines (e.g., USB VBUS protection). | Select only when forward current ≤200 mA and board space permits larger SOD-123 layout. |
| Vishay VS-2EDH01HM3/85A | Higher VR (40 V), same 1 A rating, but VF = 550 mV @ 1 A and no AEC-Q101 qualification. | Lacks automotive qualification; requires additional reliability validation for vehicle programs. | Acceptable for industrial power supplies but not recommended for OEM automotive BOMs without requalification. |
Compared with BAT760-QX, NSR0230HT1G trades current capability for lower VF in smaller-signal roles, while VS-2EDH01HM3/85A offers higher voltage headroom at the cost of automotive compliance - making BAT760-QX the only AEC-Q101-qualified 1 A / 20 V Schottky in SOD323 for production automotive designs.

FAQ
Is BAT760-QX suitable for 24 V commercial vehicle applications?
No - BAT760-QX has a 20 V maximum reverse voltage rating, making it unsuitable for nominal 24 V systems where transients exceed this limit. For 24 V applications, consider Nexperia's BAT760D (40 V VR) or equivalent AEC-Q101 diodes with ≥40 V rating. Always verify pulse-withstand capability against ISO 16750-2 profiles.
What is the maximum allowable PCB copper area for thermal performance?
The datasheet specifies two thermal resistance benchmarks: 220 K/W with 10×10 mm² cathode pad and 180 K/W with 40×40 mm². No upper limit is defined, but increasing copper beyond 40×40 mm² yields diminishing returns. Thermal simulation is recommended for layouts exceeding 40×40 mm² or operating above 85 °C ambient.
Does BAT760-QX support reflow soldering per JEDEC J-STD-020?
Yes - Nexperia qualifies BAT760-QX for standard lead-free reflow per JEDEC J-STD-020D.3, with peak temperature ≤260 °C and time above liquidus ≤60 seconds. The SOD323 package outline and solder land pattern (Fig. 5) are fully compatible with Class 3 assembly processes.
Can BAT760-QX replace BAT54 in existing designs?
Only with design review - BAT760-QX has higher current (1 A vs. 0.2 A) and voltage (20 V vs. 30 V) ratings but larger VF (480 mV vs. 370 mV at 0.1 A). Its SOD323 footprint matches BAT54, but thermal and electrical margins differ significantly; verify junction temperature rise and transient clamping behavior before substitution.
