Product details
Overview
D4V5H1BS2LP-7B from Diodes Incorporated is a single-channel bidirectional TVS diode designed for ESD and surge protection of high-speed data lines in portable electronics. It features a 4.8V minimum breakdown voltage, ±30kV IEC 61000-4-2 contact/air ESD rating, 60A peak pulse current (8/20µs), 120pF typical capacitance, and is housed in an ultra-compact X1-DFN1006-2 package - ideal for USB 2.0, HDMI, and audio jack interfaces in smartphones and wearables.
For engineers reviewing the D4V5H1BS2LP-7B datasheet, D4V5H1BS2LP-7B pinout, D4V5H1BS2LP-7B application, or D4V5H1BS2LP-7B equivalent, key selection criteria include clamping voltage at 60A (8.8V), low-profile footprint (1.1mm × 0.7mm), RoHS-compliant lead-free terminations, and IEC 61000-4-5 surge compliance - all critical for space-constrained, high-reliability consumer interface protection.
Technical Context
This bidirectional TVS operates symmetrically between its two terminals, enabling robust transient suppression on differential or single-ended signal paths without polarity constraints. Its low 5.5V clamping voltage at 1A and 8.8V at 60A ensures minimal overvoltage exposure to downstream ICs during fast transients.
The device leverages silicon avalanche structure with optimized junction design to achieve high ESD immunity (±30kV) while maintaining low capacitance (120pF @ 0V, 1MHz), preserving signal integrity on high-speed lines up to ~300MHz bandwidth.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | DO-214AC package (4.5mm × 2.7mm), 5.0V VRWM, 9.2V VCL @ 60A - larger size, higher clamping | Suitable for industrial PCBs with less space constraint; not viable for mobile PCBs | Select when board area >2× available and higher clamping voltage is acceptable |
| SP1003-04HTG | SOD-323 package (1.7mm × 1.3mm), 4.5V VRWM, 11.5V VCL @ 60A, 150pF - 25% higher capacitance | Better for lower-speed interfaces (e.g., UART); marginal for USB 2.0 eye margin | Choose only if layout allows 150pF and footprint tolerance exceeds 1.1mm × 0.7mm |
Compared with SMAJ5.0A and SP1003-04HTG, D4V5H1BS2LP-7B delivers the smallest footprint and lowest clamping voltage among these three, making it uniquely suited for miniaturized consumer interfaces where both space and signal integrity are non-negotiable.

FAQ
What is the maximum clamping voltage of D4V5H1BS2LP-7B under full-rated surge current?
The maximum clamping voltage is 8.8V at 60A peak pulse current with an 8/20µs waveform, measured pin-to-pin. This value is specified in the Electrical Characteristics table of DS42872 Rev. 1–2, page 2, and ensures protected ICs experience no more than 8.8V overshoot during worst-case lightning-induced surges.
Can D4V5H1BS2LP-7B be used on a 5V logic line without risk of premature conduction?
Yes - its reverse working voltage (VRWM) is rated at 4.5V maximum, providing 0.5V margin below 5V nominal rails. With only 0.5µA leakage at VRWM, it introduces negligible loading and will not conduct under steady-state 5V operation, only activating above ~4.8V during transients.
Is the X1-DFN1006-2 package compatible with standard reflow profiles for lead-free assembly?
Yes - the device is qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1 and supports standard Pb-free reflow profiles (peak 260°C, 10s max). Its NiPdAu terminations ensure reliable solder wetting and intermetallic formation on OSP- or ENIG-finished PCBs.
Does D4V5H1BS2LP-7B meet automotive qualification standards such as AEC-Q101?
No - this part is not AEC-Q101 qualified. Diodes Incorporated explicitly states in the datasheet that automotive-grade variants require specific change control, PPAP capability, and IATF 16949 manufacturing; D4V5H1BS2LP-7B is intended for commercial portable electronics only.
