Taiwan Semiconductor Corporation TESDH5V0B05P1Q1 M5G

Overview

TESDH5V0B05P1Q1 from Taiwan Semiconductor is a bi-directional ultra-low capacitance ESD protection diode designed for single-line high-speed data interface protection. It delivers ±20kV IEC61000-4-2 contact/air discharge immunity, 0.40pF typical junction capacitance, 9.8V clamping voltage at 16A TLP, and operates up to +85°C in DFN1006-2L package-ideal for USB 2.0/3.0 and HDMI 1.3/1.4 signal line protection.

For engineers reviewing the TESDH5V0B05P1Q1 datasheet, TESDH5V0B05P1Q1 pinout, TESDH5V0B05P1Q1 application, or TESDH5V0B05P1Q1 equivalent, key selection criteria include bidirectional 5V-rated ESD clamping, sub-0.5pF capacitance for minimal signal distortion, low dynamic resistance (0.37Ω), and compliance with IEC61000-4-5 lightning surge (5.5A, 8/20μs).

Technical Context

The TESDH5V0B05P1Q1 integrates two steering diodes and one TVS clamping cell in a single-channel configuration, enabling bidirectional transient current diversion to ground during ESD events. Its solid-state silicon-avalanche triggering ensures fast turn-on (<1ns) and stable clamping across temperature.

Designed specifically for 5V and below operating voltage systems, it maintains ultra-low leakage (2nA typ. at 5V) and supports high-frequency interfaces via 0.4pF capacitance measured at 1MHz and 0V bias-critical for preserving signal integrity in USB 3.0 and HDMI 1.4 applications.

FAQ

What is the maximum operating voltage for TESDH5V0B05P1Q1?

The TESDH5V0B05P1Q1 has a reverse working voltage (VRWM) of 5V, meaning it is rated for continuous operation in circuits with DC bias up to 5V. This makes it suitable for protecting 3.3V and 5V I/O lines, including USB 2.0/3.0, HDMI, and SATA interfaces. Exceeding 5V may cause premature conduction or reliability degradation. The TESDH5V0B05P1Q1 datasheet specifies VRWM = 5V with no minimum value-confirming strict 5V system compatibility.

Does TESDH5V0B05P1Q1 support bidirectional ESD protection?

Yes, the TESDH5V0B05P1Q1 provides true bidirectional protection using an internal symmetric diode pair architecture. Both pins function as cathodes, allowing clamping of positive and negative transients to ground without polarity constraints. This eliminates the need for external orientation checks during placement and ensures robust ±20kV IEC61000-4-2 protection on any single-ended or differential line. The TESDH5V0B05P1Q1 achieves this in a 2-pin DFN1006-2L package with no additional components required.

What is the junction capacitance of TESDH5V0B05P1Q1 and why does it matter?

The TESDH5V0B05P1Q1 exhibits 0.40pF typical junction capacitance at 1MHz and 0V bias. This ultra-low value is critical for high-speed data interfaces like USB 3.0 (5Gbps) and HDMI 1.4 (340MHz TMDS), where excess capacitance causes signal attenuation, rise-time degradation, and eye-diagram closure. At 0.4pF, the TESDH5V0B05P1Q1 introduces negligible loading-preserving signal integrity while delivering full ±20kV ESD immunity. Measured values stay within 0.4–0.5pF across production lots.

How does TESDH5V0B05P1Q1 perform under IEC61000-4-5 lightning surge conditions?

The TESDH5V0B05P1Q1 withstands 5.5A peak pulse current under the IEC61000-4-5 8/20μs waveform, corresponding to 46W non-repetitive peak pulse power. Its clamping voltage remains ≤8.5V at 5.5A, ensuring downstream 5V-tolerant ICs remain within safe operating limits. This performance is validated across temperature (−40°C to +85°C) and supports front-end protection of external ports such as HDMI, eSATA, and USB Type-A/B connectors. The TESDH5V0B05P1Q1's 0.37Ω dynamic resistance further stabilizes clamping behavior during fast-rising surges.

Is TESDH5V0B05P1Q1 compatible with automated SMT assembly processes?

Yes, the TESDH5V0B05P1Q1 uses the industry-standard DFN1006-2L package (1.0 × 0.6 mm, 0.4 mm pitch) and is qualified to moisture sensitivity level 1 per J-STD-020-meaning it can be stored indefinitely at ≤30°C/60% RH and subjected to standard reflow profiles (e.g., JEDEC J-STD-020 Class 3) without baking. Its halogen-free and RoHS-compliant construction meets IPC-J-STD-002/003 requirements. The TESDH5V0B05P1Q1 is supplied in 7" tape-and-reel (10,000 units/reel), optimized for high-speed pick-and-place equipment.
