Product details
Overview
D6V3H1U2LP-7B from Diodes Incorporated is a unidirectional transient voltage suppression (TVS) diode designed for ESD protection of high-speed data lines in portable electronics. It features a 6.5V minimum breakdown voltage, 30A peak pulse current (8/20µs), 200pF typical junction capacitance at 0V, ±30kV IEC 61000-4-2 contact/air discharge rating, and is housed in an X1-DFN1006-2 package (1.08mm × 0.68mm, 0.53mm max height).
For engineers reviewing the D6V3H1U2LP-7B datasheet, D6V3H1U2LP-7B pinout, D6V3H1U2LP-7B application, or D6V3H1U2LP-7B equivalent, this device is selected for low-capacitance, high-ESD-survivability interface protection in space-constrained USB, audio, and camera signal paths where clamping voltage ≤11.0V at 20A and thermal resistance of 500°C/W are critical.
Technical Context
This TVS operates as a single-channel, unidirectional clamp between I/O line and ground, activating above 6.5V reverse breakdown to divert ESD transients. Its 200pF capacitance enables use on 480Mbps USB 2.0 and stereo audio lines without signal integrity degradation.
The device uses silicon avalanche technology with NiPdAu-plated copper leadframe terminals, rated for ±30kV contact/air ESD per IEC 61000-4-2, and derates linearly from 250mW at 25°C to zero at 150°C ambient per its 500°C/W RθJA.

IC Role / Device Role: One D6V3H1U2LP-7B per signal line, mounted adjacent to connector to minimize trace inductance. Use Value: 6.5V VBR aligns with 1.8V/3.3V sensor I/O rails; 30A IPP handles multi-kV discharge without parametric shift. | Use Scenario: Protecting mechanical button matrix scan lines (e.g., volume up/down) from user-finger ESD in sealed MP3 players. IC Role / Device Role: TVS placed inline between button pad and microcontroller GPIO, operating in reverse-bias standby. Use Value: 6.3V VRWM supports 5V-tolerant MCU inputs; 250mW PD allows sustained operation in 60°C enclosure environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A | DO-214AC package (4.5×2.7mm), 6.0V VRWM, 35A IPP, 400pF CT | Higher capacitance limits use to low-speed lines; larger footprint incompatible with sub-2mm board edges | Select when higher surge margin is needed and board space permits larger package |
| ESD5Z6.0 | SOD-523 package (1.3×0.8mm), 6.0V VRWM, 12A IPP, 120pF CT | Lower IPP restricts use to consumer-grade ESD exposure; smaller size increases solder joint reliability risk | Select when ultra-low capacitance is prioritized over 30kV ESD immunity |
Compared with SMAJ6.0A and ESD5Z6.0, D6V3H1U2LP-7B uniquely balances 30A surge capability, 200pF capacitance, and 1.08×0.68mm footprint-enabling certified ESD protection on high-speed, space-constrained interfaces where alternatives force trade-offs in size, speed, or robustness.

FAQ
What is the maximum operating temperature range for D6V3H1U2LP-7B?
The device operates reliably from –65°C to +150°C, with power dissipation derating linearly from 250mW at 25°C to zero at 150°C ambient, based on its 500°C/W junction-to-ambient thermal resistance on standard FR-4 PCB layout.
Does D6V3H1U2LP-7B meet automotive AEC-Q200 requirements?
No-D6V3H1U2LP-7B is not AEC-Q200 qualified. It is specified for commercial and portable consumer applications. For automotive use, Diodes offers the AEC-Q200-qualified D3V3F1U2LP series with identical electrical specs but extended qualification testing.
How is polarity identified on the D6V3H1U2LP-7B package?
Polarity is marked by a bar on the cathode side (Pin 2) visible in the bottom view; Pin 1 (anode) is opposite the bar. The top-side marking "P3" is the product type code and does not indicate polarity-orientation must be confirmed using the bar indicator per the mechanical drawing.
Can D6V3H1U2LP-7B be used for bidirectional signal lines like USB D+ and D−?
No-it is unidirectional and intended for single-ended lines referenced to ground. For bidirectional differential pairs, two D6V3H1U2LP-7B units (one per line to ground) are required, or a dedicated bidirectional TVS such as D5V0H1U2LP should be selected instead.
