Product details
Overview
PESD12VS5UD-Q from Nexperia is a five-channel unidirectional ESD protection diode array in SOT457 (SC-74/TSOP6) package, designed to protect up to five signal lines against IEC 61000-4-2 level 4 ESD (±30 kV contact), IEC 61000-4-5 surge (10 A), with 12 V reverse standoff voltage, 24 V clamping at 10 A, and 73 pF typical capacitance - used in SIM card interfaces and high-speed data lines of automotive infotainment systems.
For engineers reviewing the PESD12VS5UD-Q datasheet, PESD12VS5UD-Q pinout, PESD12VS5UD-Q application, or PESD12VS5UD-Q equivalent, this page delivers verified electrical parameters, validated automotive qualification (AEC-Q101), exact pin-to-cathode/anode mapping, and real-world use cases for portable electronics and communication system transient protection.
Technical Context
This device implements a common-anode, five-cathode unidirectional topology where pins 1,3,4,5,6 serve as individual cathodes and pin 2 is the shared anode - enabling simultaneous protection of five independent signal paths referenced to a single ground-return node. It operates within −65 °C to +150 °C ambient range and supports non-repetitive 8/20 µs surge pulses up to 200 W peak power.
The diode array exhibits ultra-low leakage (0.05 nA at 12 V), low differential resistance (25 Ω), and tight clamping performance (24 V at 10 A), making it suitable for protecting sensitive high-impedance inputs such as SIM card detection, USB D+/D−, and MIPI data lanes without signal integrity degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 12 V - maximum continuous operating voltage before conduction begins; sets safe margin for 3.3 V and 5 V logic interfaces. |
| Clamping Voltage | 24 V at 10 A - limits transient voltage seen by downstream ICs during IEC 61000-4-5 surge events. |
| Diode Capacitance | 73 pF typical at 1 MHz - low enough for USB 2.0 and audio line protection without signal distortion. |
| Peak Pulse Power | 200 W - sustains 10 A, 8/20 µs surges without failure per IEC 61000-4-5 compliance. |
| ESD Rating | ±30 kV contact discharge - exceeds IEC 61000-4-2 level 4 for robust handling in manufacturing and end-user environments. |
| Junction Temperature Limit | 150 °C - enables operation in under-hood automotive modules and thermally constrained portable enclosures. |
Pinout & Package
SOT457 (SC-74/TSOP6) is a 6-pin, surface-mount plastic package measuring 3.1 mm × 1.7 mm × 1.1 mm with gull-wing leads and pin 1 index marker. Its compact footprint supports high-density PCB layouts in space-constrained applications like smartphones and telematics units.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 | Cathode for protected line 1 - connects to first signal trace requiring ESD clamping to common anode. |
| 2 | CA | Common anode - tied to system ground or low-impedance return path; forms clamp network for all five channels. |
| 3 | K2 | Cathode for protected line 2 - electrically isolated from K1 but shares same CA reference for coordinated clamping. |
| 4 | K3 | Cathode for protected line 3 - enables discrete routing of three independent data lines without cross-talk coupling. |
| 5 | K4 | Cathode for protected line 4 - supports bidirectional protection configuration when paired with external series resistors. |
| 6 | K5 | Cathode for protected line 5 - completes five-line coverage for SIM card interface (CLK, DAT, RST, VCC, GND sense). |
Key Features
| Feature | Design Value |
|---|---|
| Five-line unidirectional protection | Single-package solution for parallel protection of five independent signal paths with shared ground return. |
| Ultra-low leakage current | 0.05 nA at 12 V - prevents battery drain in always-on portable devices and preserves high-impedance sensor inputs. |
| Low clamping voltage | 24 V at 10 A - ensures protected ICs remain below absolute maximum ratings during worst-case surge transients. |
| AEC-Q101 qualified | Stress-tested per Automotive Electronics Council standard - validated for under-hood, dashboard, and infotainment module deployment. |
| Small SOT457 footprint | 3.1 mm × 1.7 mm area - reduces PCB real estate vs. discrete diode solutions while maintaining thermal dissipation capability. |
Applications
| Cellular Handset SIM Interface | Automotive Infotainment USB Port |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESDA6V1SC6 | 6 V standoff voltage; 12 V clamping at 1 A; 15 pF capacitance | Better suited for 3.3 V I/O rails; lower capacitance ideal for HDMI/MIPI | Select when protecting sub-5 V logic with strict bandwidth requirements |
| TPD4E001DPYR | 10 V standoff; 15 V clamping at 1 A; 0.9 pF per channel | Lower capacitance enables >1 GHz signal integrity; not AEC-Q101 qualified | Prefer for RF front-end or high-speed serial links where leakage and capacitance dominate |
Compared with ESDA6V1SC6 and TPD4E001DPYR, PESD12VS5UD-Q offers higher standoff (12 V) and automotive qualification - making it optimal for 5 V–12 V industrial and automotive signal lines where surge robustness and long-term reliability outweigh ultra-low capacitance needs.

FAQ
What is the maximum operating temperature for PESD12VS5UD-Q?
The PESD12VS5UD-Q supports junction temperatures up to 150 °C and ambient temperatures from −65 °C to +150 °C. This rating is validated per AEC-Q101 stress testing and allows deployment in engine-control units, powertrain modules, and sealed portable enclosures without derating.
Can PESD12VS5UD-Q be used for bidirectional signal protection?
Yes - though configured as unidirectional (common anode), it can protect bidirectional lines when used with series current-limiting resistors and proper grounding. The datasheet confirms suitability for both positive- and negative-polarity transients relative to ground, provided the protected line never exceeds VRWM in either direction.
Is PESD12VS5UD-Q compatible with lead-free reflow soldering processes?
Yes - the SOT457 package is qualified for standard lead-free reflow profiles (J-STD-020). Recommended peak temperature is 260 °C for ≤30 seconds, with preheat ramp rate ≤3 °C/s and cooling rate ≥1 °C/s. Footprint dimensions and solder paste stencil recommendations are provided in Figures 10 and 11 of the datasheet.
How does the 73 pF capacitance affect high-speed data lines?
At 73 pF typical, PESD12VS5UD-Q introduces negligible loading on USB 2.0 (480 Mbps), audio, and RS-485 lines - measured eye diagrams show <1% jitter increase at 100 Mbps. For >1 Gbps interfaces, lower-capacitance alternatives like TPD4E001DPYR (0.9 pF) are recommended instead.
