Product details
Overview
D50V0S1U2LP1610-7 from Diodes Incorporated is a single-channel unidirectional TVS diode designed for board-level transient voltage suppression in I/O lines. It features a 50 V reverse standoff voltage, 88 V max clamping voltage at 15 A peak pulse current, ±30 kV ESD protection (IEC 61000-4-2), 132 pF channel input capacitance, and U-DFN1610-2 (Type B) package - deployed in USB voltage bus and battery protection circuits.
For engineers reviewing the D50V0S1U2LP1610-7 datasheet, D50V0S1U2LP1610-7 pinout, D50V0S1U2LP1610-7 application, or D50V0S1U2LP1610-7 equivalent, key selection criteria include clamping voltage under 8×20 µs lightning surge, low capacitance for high-speed data lines, IEC 61000-4-2 ±30 kV contact/air ESD rating, thermal derating above +25°C, and compatibility with FR-4 PCB layouts using Diodes' recommended pad dimensions.
Technical Context
This TVS diode operates as a unidirectional clamping device between an I/O line and ground, triggered when transient voltage exceeds its 50 V standoff threshold. Its silicon avalanche structure delivers precise breakdown at 56–63 V (min/max) with 1 mA test current and sustains 15 A peak pulse current per IEC 61000-4-5 8×20 µs waveform.
Thermal performance is defined by 417 °C/W junction-to-ambient resistance on standard 2 oz copper FR-4 layout, enabling operation from –55 °C to +150 °C. The device exhibits <200 nA reverse leakage at VRWM and maintains stable clamping behavior across ambient temperatures up to +125 °C before derating begins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 50 V - Maximum continuous DC operating voltage before clamping initiates; sets safe margin below system rail. |
| Breakdown Voltage (Min/Max) | 56 V / 63 V @ 1 mA - Confirmed avalanche onset range ensures reliable triggering without premature conduction. |
| Max Clamping Voltage | 88 V @ 15 A (8×20 µs) - Limits transient voltage seen by protected IC to safe level during lightning surge events. |
| ESD Protection Level | ±30 kV air & contact discharge - Meets highest IEC 61000-4-2 Class 4 immunity requirement for handheld electronics. |
| Channel Input Capacitance | 132 pF @ 0 V, 1 MHz - Low enough for USB 2.0 signal integrity; measured I/O-to-GND, not differential. |
| Peak Pulse Current | 15 A - Sustained surge capability per IEC 61000-4-5; derates linearly above +25°C ambient per published curve. |
| Package | U-DFN1610-2 (Type B) - 1.6 mm × 1.0 mm × 0.5 mm footprint with NiPdAu terminals; optimized for automated placement and reflow. |
Pinout & Package
U-DFN1610-2 (Type B) is a 2-terminal, bottom-exposed thermal pad package with cathode marked by dot. Pin 1 is anode; Pin 2 is cathode. Designed for surface-mount assembly on compact PCBs with minimal parasitic inductance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode) | Input/Line Terminal | Connected to protected signal line (e.g., USB D+); conducts surge current toward ground when clamped. |
| Pin 2 (Cathode) | Ground Reference Terminal | Connected to system ground plane; provides low-inductance return path for transient energy dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| IEC 61000-4-2 ESD robustness | ±30 kV contact/air - Eliminates need for secondary ESD stages in mobile accessory designs. |
| Low clamping voltage | 88 V @ 15 A - Keeps downstream logic ICs within absolute maximum ratings during 8×20 µs surges. |
| Controlled input capacitance | 132 pF - Preserves signal rise/fall times on 480 Mbps USB 2.0 buses without added jitter. |
| Green, halogen-free construction | <900 ppm Br/Cl, <1000 ppm Sb - Complies with JEDEC J-STD-709B and automotive OEM material declarations. |
| Moisture sensitivity level | MSL 1 - No bake required prior to reflow; supports standard SMT production flow without handling constraints. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ50A (DO-214AC) | Higher clamping voltage (96 V), larger 5.3 mm × 2.7 mm package, 200 pF capacitance | Not suitable for space-constrained USB 2.0 interfaces; better for industrial 24 V supply rails | Select when board area allows DO-214AC and higher clamping is acceptable for 24 V systems. |
| SP1003-050 (SOD-323) | Same 50 V standoff but lower 12 A Ipp rating, 105 pF capacitance, smaller 1.7 mm × 1.3 mm footprint | Better for ultra-low-capacitance applications like MIPI D-PHY, but less robust for lightning surges | Choose for high-density sensor nodes where 15 A surge headroom is not required and 105 pF is critical. |
Compared with SMAJ50A and SP1003-050, D50V0S1U2LP1610-7 uniquely balances 15 A surge capability, 132 pF capacitance, and 1.6 mm × 1.0 mm footprint - making it optimal for USB 2.0 and battery-line protection where both space and transient robustness are constrained.

FAQ
What is the maximum operating temperature for D50V0S1U2LP1610-7?
The device operates from –55 °C to +150 °C, with thermal derating beginning above +25 °C ambient. At +85 °C, its peak pulse current capability reduces to ~70% of the rated 15 A value, per the published derating curve. This enables use in sealed enclosures or near heat-generating components without external heatsinking.
Is D50V0S1U2LP1610-7 compatible with lead-free reflow profiles?
Yes - it is fully RoHS 3 compliant and qualified for standard lead-free reflow profiles with peak temperatures up to 260 °C. Its NiPdAu-plated terminals ensure solderability per MIL-STD-202, Method 208, and its MSL 1 rating eliminates pre-bake requirements, supporting high-yield SMT assembly.
How does the 132 pF capacitance affect USB 2.0 signal integrity?
At 132 pF, the device introduces <1% signal attenuation at 480 MHz (USB 2.0 fundamental), preserving eye diagram opening and jitter margins. Measured I/O-to-GND capacitance avoids differential-mode distortion, and its placement within 3 mm of the connector minimizes stub inductance that could degrade high-frequency response.
Can D50V0S1U2LP1610-7 replace D36V0S1U2LP1610-7 in a 3.3 V I/O line?
No - D50V0S1U2LP1610-7's 50 V standoff is mismatched for 3.3 V logic; D36V0S1U2LP1610-7 (36 V standoff) provides appropriate margin. Using the 50 V part risks insufficient clamping during lower-voltage transients and violates design intent for 3.3 V rail protection per IEC 61000-4-2 testing protocols.
