Product details
Overview
TESDL24VB17P1Q1 from Taiwan Semiconductor is a bidirectional ESD protection diode in DFN1006-2L package, rated for ±30 kV IEC61000-4-2 (air/contact), 3 A peak pulse current (8/20 µs), 24 V reverse working voltage, and 50 V clamping voltage at 3 A - deployed on power and control lines in portable instrumentation and PCB-level 24 V system protection.
For engineers reviewing the TESDL24VB17P1Q1 datasheet, TESDL24VB17P1Q1 pinout, TESDL24VB17P1Q1 application, or TESDL24VB17P1Q1 equivalent, key selection factors include clamping voltage under 3 A surge, junction capacitance below 17.5 pF at 0 V, dynamic resistance ≤0.45 Ω, compliance with IEC61000-4-4 (4 kV EFT), and moisture sensitivity level 1 handling.
Technical Context
This device implements a proprietary bidirectional clamping cell architecture optimized for transient suppression on low-speed I/O and power rails. It delivers symmetrical breakdown behavior (VBR = 25.2–32.6 V) and low dynamic resistance (0.45 Ω typical) to minimize voltage overshoot during fast transients like ESD and lightning surges.
Designed for 24 V systems, it operates across –55 °C to +125 °C, supports 100 ns TLP testing (VCL = 31 V at 2 A, 33.7 V at 8 A), and maintains <50 nA leakage at 24 V - enabling robust protection without signal integrity degradation in space-constrained layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse working voltage | 24 V - maximum continuous DC or RMS operating voltage before leakage rises significantly |
| Clamping voltage @ 3 A (8/20 µs) | 50 V - peak line voltage seen by downstream ICs during IEC61000-4-5 surge events |
| Junction capacitance @ 1 MHz, 0 V | 13.9–17.5 pF - minimal loading on low-speed data/control lines (e.g., UART, GPIO, power enable) |
| Dynamic resistance | 0.45 Ω typical - ensures rapid voltage collapse during ESD transients, reducing energy dissipation in protected circuitry |
| ESD rating (IEC61000-4-2) | ±30 kV contact & air - meets highest industrial immunity requirement for handheld and field-deployed equipment |
| Peak pulse current (8/20 µs) | 3 A - withstands lightning-induced surges per IEC61000-4-5 Level 3 |
| Moisture sensitivity level | Level 1 (J-STD-020) - no bake required prior to reflow, simplifying SMT assembly |
Pinout & Package
DFN1006-2L package: 1.075 × 0.675 mm, 0.3 mm height, cathode-indicated via notch/chamfer on terminal II; RoHS-compliant, halogen-free, and MSL-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal I | Anode (bidirectional) | One side of symmetrical clamping path; connects to protected line (e.g., VIN, GPIO) |
| Terminal II | Cathode (marked) | Reference node (typically GND or common rail); defines polarity marking for orientation during placement |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection on unidirectional or AC-coupled lines without polarity constraints |
| Low clamping voltage (50 V @ 3 A) | Keeps protected ICs within safe absolute maximum ratings during 8/20 µs surges |
| 13.9–17.5 pF junction capacitance | Preserves signal rise/fall times on lines up to ~10 MHz (e.g., SMBus, I²C, push-button inputs) |
| 0.45 Ω dynamic resistance | Reduces clamping voltage overshoot and improves energy diversion efficiency vs. higher-RDYN alternatives |
| IEC61000-4-4 EFT immunity (4 kV) | Supports reliable operation in electrically noisy industrial environments with repetitive fast transients |
Applications
| Portable Instrumentation | 24 V Power Rail Protection |
|---|---|

IC Role / Device Role / Timing Role: Low-capacitance transient suppressor placed adjacent to connector footprint. Use Value: 17.5 pF max capacitance prevents signal distortion on 100 kbps–1 Mbps control signals while meeting ±30 kV ESD immunity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Semtech RCLAMP0524P.TCT | Higher VRWM (5 V), lower clamping (24 V @ 3 A), 12 pF typical capacitance | Optimized for 3.3–5 V logic lines; unsuitable for 24 V rails due to premature conduction | Select only for low-voltage I/O; not interchangeable with TESDL24VB17P1Q1 in 24 V systems |
| Littelfuse SP3205-01UTG | Same VRWM (24 V), higher clamping (60 V @ 3 A), 18 pF max capacitance, MSL-3 | Acceptable for 24 V power lines but requires baking before reflow; slightly higher voltage stress on protected ICs | Use where MSL-1 is not mandatory and 10 V higher clamping is tolerable |
Compared with RCLAMP0524P.TCT and SP3205-01UTG, the TESDL24VB17P1Q1 uniquely balances 24 V operation, 50 V clamping, MSL-1 handling, and 17.5 pF capacitance - making it optimal for space-constrained 24 V industrial I/O where process simplicity and voltage margin are critical.

FAQ
What is the maximum continuous operating voltage for the TESDL24VB17P1Q1?
The TESDL24VB17P1Q1 has a reverse working voltage (VRWM) of 24 V, meaning it can safely block up to 24 V DC or RMS in normal operation without significant leakage. This rating ensures compatibility with standard 24 V industrial power rails and control circuits while maintaining <50 nA leakage at rated voltage - critical for preserving signal integrity and power efficiency in always-on systems.
Does the TESDL24VB17P1Q1 meet IEC61000-4-2 Level 4 ESD requirements?
Yes, the TESDL24VB17P1Q1 exceeds IEC61000-4-2 Level 4, delivering ±30 kV ESD protection for both contact and air discharge - the highest defined test level in the standard. This performance is achieved through its proprietary bidirectional clamping cell design and verified in third-party lab testing per the specification, making the TESDL24VB17P1Q1 suitable for demanding end-equipment certifications in industrial and medical-adjacent applications.
What is the clamping voltage of the TESDL24VB17P1Q1 under a 3 A 8/20 µs surge?
The clamping voltage of the TESDL24VB17P1Q1 is specified as ≤50 V when subjected to a 3 A, 8/20 µs current waveform per IEC61000-4-5. This value represents the maximum voltage that appears across the device terminals during the surge event and directly determines the stress imposed on downstream components - ensuring ICs with 55 V absolute maximum ratings remain fully protected.
Is the TESDL24VB17P1Q1 compatible with lead-free reflow processes?
Yes, the TESDL24VB17P1Q1 is qualified for standard lead-free reflow profiles (JEDEC J-STD-020), with a moisture sensitivity level (MSL) of 1 - meaning it may be stored indefinitely at ambient conditions and placed directly into reflow without pre-baking. Its DFN1006-2L package uses matte tin terminations and passes thermal cycling and solderability tests per industry standards.
How does the dynamic resistance of the TESDL24VB17P1Q1 affect its ESD performance?
The TESDL24VB17P1Q1 exhibits a typical dynamic resistance (RDYN) of 0.45 Ω, measured between 2 A and 8 A TLP pulses. This low value enables faster voltage collapse during ESD events, reducing both clamping voltage overshoot and total energy dissipated in the protected circuit - directly improving reliability of sensitive downstream components such as microcontrollers and analog front-ends in the TESDL24VB17P1Q1-protected system.
