Product details
Overview
D3V3L4BS4LP1308-7 from Diodes Incorporated is a 4-channel bidirectional TVS diode array designed for ESD and surge protection of high-speed data lines in portable electronics. It features a reverse working voltage of 3.3 V, minimum breakdown voltage of 3.8 V, peak pulse current rating of 11 A (8/20 µs), typical junction capacitance of 9.5 pF, and IEC 61000-4-2 ±30 kV (contact/air) ESD immunity - deployed in cellular handsets, digital cameras, and MP3 players.
For engineers reviewing the D3V3L4BS4LP1308-7 datasheet, D3V3L4BS4LP1308-7 pinout, D3V3L4BS4LP1308-7 application, or D3V3L4BS4LP1308-7 equivalent, key selection criteria include low clamping voltage (4.8 V @ 1 A), ultra-low capacitance for signal integrity, bidirectional channel symmetry, and compatibility with space-constrained DFN1308 packaging for USB, HDMI, and audio interface protection.
Technical Context
This TVS array uses silicon avalanche diode structures arranged in four independent, symmetrical bidirectional pairs between I/O pins and ground. Each channel provides low dynamic resistance (0.16 Ω) and fast TLP response (100 ns pulse), enabling effective transient suppression without signal distortion on high-frequency lines.
It operates within –55 °C to +150 °C, supports 250 mW power dissipation on standard FR-4 PCB layout, and maintains stable clamping performance across temperature due to its monolithic DFN construction and NiPdAu-plated copper leadframe.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ3.3A-Q | Unidirectional, SMA package (4.5 mm × 2.7 mm), higher CT (~25 pF), lower IPP (24.7 A) | Requires polarity-aware routing; unsuitable for AC-coupled or differential lines | Select only when board space allows larger package and unidirectional protection suffices |
| SP1006-04UTG | 4-channel bidirectional, SOT-23-6 package, CT = 12 pF, VBR min = 3.6 V, IPP = 8 A | Larger footprint (2.9 mm × 1.6 mm); higher capacitance limits use in >100 Mbps interfaces | Prefer where legacy SOT-23 assembly infrastructure exists and 12 pF is acceptable |
Compared with SMAJ3.3A-Q and SP1006-04UTG, D3V3L4BS4LP1308-7 delivers superior high-speed interface compatibility via its 9.5 pF capacitance and DFN1308 footprint, while maintaining full bidirectionality and industry-leading ±30 kV ESD rating in the smallest available form factor.

FAQ
What is the maximum operating temperature for D3V3L4BS4LP1308-7?
The device is rated for continuous operation from –55 °C to +150 °C ambient temperature. Its thermal resistance (RθJA = 500 °C/W) assumes mounting on a standard FR-4 PCB with 2 oz copper per Diodes' recommended pad layout; derating begins above +70 °C ambient per Figure 1 in DS43449.
Does D3V3L4BS4LP1308-7 require external biasing or control signals?
No. It is a passive, always-active TVS diode array with no enable pins, supply rails, or configuration requirements. Protection engages automatically when transient voltage exceeds the 3.8 V breakdown threshold, making it ideal for plug-and-play interface hardening.
Can D3V3L4BS4LP1308-7 be used on USB 3.0 or HDMI interfaces?
No - its 9.5 pF typical capacitance is optimized for USB 2.0 (<480 Mbps), audio, and low-speed data lines. USB 3.0 and HDMI require sub-2 pF solutions to avoid signal integrity failure; this device would cause excessive insertion loss and jitter on those interfaces.
How is the marking code 'QZ4' interpreted on the device top-side?
'QZ4' is the product type marking per Diodes' coding scheme, indicating the D3V3L4BS4LP1308-7 variant. The backside includes date code 'YM', where 'Y' (e.g., J = 2022) and 'M' (e.g., N = November) denote manufacturing year and month, respectively, per the datasheet's Date Code Key table.
