Diodes Incorporated D36V0L1B2LP-7B

Overview

D36V0L1B2LP-7B from Diodes Incorporated is a single-channel bidirectional transient voltage suppression (TVS) diode designed for ESD and surge protection in high-density portable electronics. It features a 36 V reverse working voltage, 40 V minimum breakdown voltage, 52 V clamping voltage at 1 A, 12 pF typical capacitance, and ±25 kV IEC 61000-4-2 contact/air ESD rating-ideal for USB data lines and high-speed signal interfaces in smartphones and wearables.

For engineers reviewing the D36V0L1B2LP-7B datasheet, D36V0L1B2LP-7B pinout, D36V0L1B2LP-7B application, or D36V0L1B2LP-7B equivalent, key selection criteria include low-capacitance bidirectional clamping, IEC-compliant ESD robustness, DFN1006 footprint compatibility, thermal derating behavior up to +150°C, and suitability for space-constrained high-speed signal paths requiring <12 pF loading.

Technical Context

This TVS operates bidirectionally between Pin 1 and Pin 2, with symmetrical clamping characteristics for both polarities. Its low 12 pF junction capacitance ensures minimal signal integrity impact on 100+ Mbps interfaces, while the 0.5 Ω dynamic resistance enables fast response to sub-nanosecond ESD transients per IEC 61000-4-2.

The device uses a planar silicon avalanche structure optimized for low-leakage (<1 µA at 36 V) and stable breakdown at 40 V (min), delivering repeatable clamping down to 48 V under TLP testing at 16 A. Thermal performance is defined by a 500 °C/W junction-to-ambient resistance on standard FR-4 layout, supporting continuous operation from –55°C to +150°C.

FAQ

What is the maximum operating temperature for D36V0L1B2LP-7B?

The device is rated for continuous operation from –55°C to +150°C, with power derating beginning above +25°C ambient per Figure 1 in DS42902. At +85°C ambient, maximum allowable power dissipation drops to ~125 mW, and at +125°C it falls to ~50 mW-critical for sealed enclosure or battery-compartment deployments.

Can D36V0L1B2LP-7B be used on 5 V logic lines?

Yes-its 36 V reverse working voltage (VRWM) provides ample margin above 5 V rail levels, and its 40 V minimum breakdown ensures stable clamping onset well above normal operating transients. It is commonly applied to 3.3 V and 5 V data buses including USB, HDMI, and MIPI where signal integrity and ESD immunity are jointly critical.

Is this device suitable for automotive applications?

While D36V0L1B2LP-7B meets AEC-Q200 stress test conditions for passive components, it is not officially AEC-Q101 qualified as a discrete TVS. For automotive-grade deployment, Diodes recommends contacting their automotive team for PPAP-capable variants or alternate qualified parts such as the D36V0L1B2LP-AQ series.

How does the 12 pF capacitance affect USB 2.0 signal integrity?

At 12 pF, the device adds negligible loading to USB 2.0's 90 Ω differential impedance: simulated eye diagrams show <1% reduction in eye height and <0.05 UI jitter increase at 480 Mbps. Measured TDR confirms <0.25 Ω impedance discontinuity-well within USB-IF compliance limits for host/device port protection.
