Product details
Overview
ESD761DPYRQ1 from Texas Instruments is a single-channel, bidirectional automotive-grade TVS diode for LIN bus ESD protection, featuring ±24V working voltage, 1.1pF typical I/O capacitance, ±15kV IEC 61000-4-2 contact discharge rating, and AEC-Q101 qualification for use in headlight modules, door ECUs, and climate control systems.
For engineers reviewing the ESD761DPYRQ1 datasheet, ESD761DPYRQ1 pinout, ESD761DPYRQ1 application, or ESD761DPYRQ1 equivalent, this page delivers verified electrical specs, X1SON package layout guidance, LIN-specific clamping performance at 1.8A (8/20µs), thermal resistance data (RθJA = 282.3°C/W), and direct alternative part comparisons for automotive signal-line robustness design.
Technical Context
The ESD761DPYRQ1 operates as a passive bidirectional clamp with VRWM = ±24V and VBR = ±25.5V minimum, activating above breakdown to divert ESD transients to ground while maintaining ultra-low leakage (≤50nA at ±24V). Its 0.53Ω dynamic resistance ensures low clamping voltage under surge conditions.
Designed specifically for LIN physical layer protection, it supports data rates up to 10Mbps due to its 1.1pF line capacitance and integrates into compact automotive ECUs via the 1.00mm × 0.60mm X1SON (DPY) leadless package with exposed thermal pad and MSL Level-1 reflow profile.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD751DYARQ1 | SOD-523 (DYA) package; 1.6pF capacitance; ±22kV IEC contact rating; 2.8A IEC 61000-4-5 surge current. | Higher capacitance limits max LIN speed to ~5Mbps; larger footprint requires more board space. | Select when higher ESD margin is prioritized over board area and data rate. |
| ESD1LIN24DYFRQ1 | SOD-323 (DYF) package; 2.3pF capacitance; ±30kV IEC contact rating; 4.3A IEC 61000-4-5 surge current. | Higher capacitance restricts use to ≤20Kbps LIN; largest footprint among the three variants. | Select for legacy designs requiring maximum surge current handling and AOI compatibility. |
Compared with ESD751DYARQ1 and ESD1LIN24DYFRQ1, ESD761DPYRQ1 offers the smallest footprint and lowest capacitance-enabling 10Mbps LIN operation in space-constrained modules-while trading off some ESD voltage margin and surge current capacity for miniaturization and thermal efficiency.

FAQ
What is the maximum LIN data rate supported by ESD761DPYRQ1?
ESD761DPYRQ1 supports LIN data rates up to 10Mbps due to its 1.1pF typical I/O capacitance, which minimizes signal rise-time degradation and maintains waveform fidelity across the standard LIN frequency band. This value is measured at 1MHz with 30mVpp bias and confirmed in TI's Electrical Characteristics table (Section 5.7).
Does ESD761DPYRQ1 require external biasing or control signals?
No, ESD761DPYRQ1 is a passive bidirectional TVS diode and requires no external power, biasing, or control logic. It remains in high-impedance state below ±24V VRWM and automatically activates during overvoltage transients. Its bidirectional architecture inherently protects both polarities without additional circuitry.
What is the thermal resistance from junction to board (RθJB) for ESD761DPYRQ1?
The junction-to-board thermal resistance (RθJB) for ESD761DPYRQ1 is 98.3°C/W, as specified in Section 5.6 of the datasheet. This value assumes proper PCB layout with thermal vias connecting the exposed pad to internal ground planes, enabling effective heat dissipation during repetitive ESD events.
Is ESD761DPYRQ1 qualified for automotive under-hood applications?
Yes, ESD761DPYRQ1 is AEC-Q101 qualified and rated for operation from –55°C to +150°C, making it suitable for under-hood environments including engine control modules, transmission controllers, and radiator fan drivers where ambient temperatures exceed 125°C.
How does the clamping voltage of ESD761DPYRQ1 compare to competing devices at 1.8A?
At 1.8A (8/20µs waveform), ESD761DPYRQ1 clamps to 36.3V - lower than ESD751DYARQ1 (36.5V at 2.8A) and significantly lower than many generic 24V TVS diodes exceeding 40V. This tight clamping ensures compatibility with LIN transceivers having 36V absolute maximum ratings, reducing risk of damage during surge events.
