Product details
Overview
BAT160S-QX from Nexperia is a planar Schottky barrier double diode in SOT223 (SC-73) package, rated for 60 V reverse voltage and 1 A continuous forward current per diode, with 850 mV forward voltage at 2 A and 25 °C. It delivers low switching losses and high surge current capability (10 A non-repetitive peak), qualified to AEC-Q101 for automotive polarity protection and low-power SMPS rectification.
For engineers reviewing the BAT160S-QX datasheet, BAT160S-QX pinout, BAT160S-QX application, or BAT160S-QX equivalent, this dual Schottky diode supports thermally demanding automotive front-end circuits where fast recovery, low VF, and junction temperature up to 150 °C are critical design requirements.
Technical Context
This dual-diode configuration integrates two independent Schottky junctions sharing a common terminal (Pin 4 = K1/A2), enabling compact bidirectional clamping or complementary rectification without external interconnect. The guard ring structure ensures stable breakdown behavior under transient stress.
Thermal resistance from junction to ambient is 100 K/W on standard FR4 PCB - a key constraint for power derating in sealed automotive enclosures. Reverse leakage remains ≤8 mA at 100 °C and 60 V, supporting reliable operation in high-temperature engine bay environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 60 V - maximum blocking voltage per diode; defines usable input range in 48 V automotive systems. |
| Forward Voltage (VF) | 850 mV @ 2 A, 25 °C - enables <1.7 W conduction loss per diode at full load, reducing thermal burden. |
| Peak Surge Current (IFSM) | 10 A @ 8.3 ms half-sine - withstands cold-crank and load-dump transients without failure. |
| Junction Temperature (Tj) | 150 °C max - allows operation in under-hood locations without active cooling. |
| Reverse Leakage (IR) | 8 mA @ 60 V, 100 °C - low enough to avoid significant standby power loss in always-on modules. |
| Diode Capacitance (Cd) | 60 pF @ 4 V, 1 MHz - minimizes high-frequency switching noise in DC-DC feedback paths. |
Pinout & Package
Package: SOT223 (SC-73), surface-mount plastic package with integrated heatsink pad (Pin 4), 6.5 mm × 3.5 mm × 1.65 mm body, 2.3 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Input terminal for first Schottky junction; connects to positive rail in polarity protection. |
| 2 | Not Connected | Internally isolated; must remain unconnected on PCB to prevent parasitic coupling. |
| 3 | Cathode (Diode 2) | Output terminal for second junction; used as return path in dual-rail clamp configurations. |
| 4 | Cathode (Diode 1) / Anode (Diode 2) | Common terminal enabling shared thermal path and compact dual-diode topology. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring protection | Prevents edge breakdown during voltage transients, ensuring stable 60 V blocking across temperature. |
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, HTRB, and ESD testing per JEDEC standards. |
| Low thermal resistance | 100 K/W junction-to-ambient enables 1 A continuous operation on standard FR4 without copper pour extension. |
| Fast recovery time | Inherent Schottky behavior eliminates minority-carrier storage delay - critical for >100 kHz SMPS efficiency. |
Applications
| Automotive Polarity Protection | Low-Power SMPS Output Rectification |
|---|---|
Use Scenario: Reverse-battery connection protection in vehicle infotainment head units and ADAS camera modules. IC Role / Device Role / Timing Role: Dual-diode configured as back-to-back series clamp, using Pin 1 and Pin 3 as inputs and Pin 4 as common ground reference.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky double diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR20F60HT1G | 60 V VR, 2 A IF, TO-277 package (smaller footprint, no thermal pad) | Lacks AEC-Q101 qualification; not approved for automotive safety-critical zones | Select when space-constrained industrial designs require higher current rating and thermal pad is not needed. |
| Vishay VS-2EDH06-M3/45 | 60 V VR, 1 A IF, SOD-123FL dual package; 950 mV VF @ 1 A | Higher VF increases conduction loss by 18 %; no guard ring; not AEC-Q101 qualified | Acceptable for cost-sensitive consumer-grade 5 V USB power paths where 150 °C Tj margin is unnecessary. |
Compared with NSR20F60HT1G and VS-2EDH06-M3/45, BAT160S-QX uniquely combines AEC-Q101 qualification, SOT223 thermal pad, and 850 mV VF at 2 A - making it the only option validated for under-hood automotive rectification requiring simultaneous surge robustness and thermal reliability.

FAQ
Is BAT160S-QX pin-compatible with BAT54S?
No. BAT160S-QX uses SOT223 with 4 pins (A1, n.c., K2, K1/A2), while BAT54S uses SOT363 with 6 pins and different internal connectivity. Pin 2 is not connected in BAT160S-QX but carries signals in BAT54S. Layout redesign and schematic review are required for substitution.
What is the maximum continuous forward current per diode at 100 °C ambient?
At Tamb = 100 °C, derating applies: Rth(j-a) = 100 K/W and Tj(max) = 150 °C allow ΔT = 50 K, limiting power dissipation to 0.5 W. With VF ≈ 750 mV at 100 °C, maximum continuous IF is approximately 0.67 A per diode - confirmed by Nexperia's thermal curves in Figure 1.
Can Pin 2 be left floating or must it be grounded?
Pin 2 is internally not connected and must remain unconnected on the PCB. Grounding or routing it creates risk of solder bridging or unintended capacitance coupling. Nexperia's package outline and pinning table explicitly define it as "n.c." with no internal bond wire.
Does BAT160S-QX support reflow soldering per J-STD-020?
Yes. Nexperia specifies compatibility with standard Pb-free reflow profiles: peak temperature 260 °C, time above liquidus 60–90 s, ramp-up rate ≤3 °C/s. Figure 5 provides the exact SC-73 footprint with solder land dimensions and paste volume guidance for process validation.
