Product details
Overview
BAV5004LP-7B from Diodes Incorporated is a high-voltage switching diode in a DFN1006-2 (X1) surface-mount package, rated for 400 V repetitive peak reverse voltage, 300 mA forward current, and 50 ns maximum reverse recovery time. It delivers low junction capacitance (2.5 pF max at 0 V) and operates across –55 °C to +150 °C, supporting fast-switching power supply snubbers and ESD-protected signal routing in automotive body control modules.
For engineers reviewing the BAV5004LP-7B datasheet, BAV5004LP-7B pinout, BAV5004LP-7B application, or BAV5004LP-7B equivalent, key selection criteria include verified VRRM = 400 V, trr ≤ 50 ns, CT ≤ 2.5 pF at 1 MHz, IF = 300 mA continuous, and AEC-Q101 qualification for under-hood reliability.
Technical Context
This diode functions as a unidirectional, high-speed switching element optimized for clamping, snubbing, and protection in DC-DC converters and interface lines. Its 400 V VRRM enables use in 24 V/48 V automotive systems with transient margin, while the 50 ns trr supports switching frequencies up to ~10 MHz in flyback snubbers.
The DFN1006-2 package provides thermal resistance of 357 °C/W (junction-to-ambient), enabling 350 mW power dissipation on FR-4 with recommended pad layout. The NiPdAu-plated copper leadframe ensures solderability per MIL-STD-202, Method 208, and moisture sensitivity level 1 compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Withstands repetitive transients up to 400 V without breakdown, suitable for 24 V/48 V automotive bus protection. |
| trr | 50 ns max - Enables clean switching in high-frequency snubber circuits with minimal tail current loss. |
| CT | 2.5 pF max at 0 V, 1 MHz - Minimizes signal loading in high-speed data line clamping applications. |
| IF | 300 mA continuous - Supports sustained current in low-power logic-level clamp and bias networks. |
| TJ Range | –55 °C to +150 °C - Qualified for engine bay and transmission control unit environments per AEC-Q101. |
| PD | 350 mW - Achievable on standard FR-4 PCB with manufacturer-recommended pad layout. |
Pinout & Package
Package: X1-DFN1006-2 - 1.0 mm × 0.6 mm, 0.5 mm height, single-row 2-terminal surface-mount plastic package with exposed thermal pad not present; terminals are NiPdAu over copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode) | Forward current entry point | Connected to lower-potential side in clamping configuration; requires trace routing for thermal relief on high-current paths. |
| 2 (Cathode) | Forward current exit / reverse blocking node | Marked with cathode line on bottom view; ties to rail or signal line requiring overvoltage protection. |
Key Features
| Feature | Design Value |
|---|---|

| Low capacitance (2.5 pF max) | Preserves signal integrity in 10–100 MHz data line protection without added rise/fall time distortion. |
| Fast recovery (50 ns max) | Reduces switching losses in 100 kHz–1 MHz DC-DC snubbers versus general-purpose rectifiers. |
| RoHS & "Green" compliant | Contains <900 ppm Br, <900 ppm Cl, <1000 ppm Sb - meets EU environmental directives and OEM sustainability requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV21W-7-F | VRRM = 250 V, trr = 50 ns, CT = 4.0 pF, SOD-123 package | Lacks AEC-Q101 qualification; higher capacitance limits >20 MHz signal use | Select only for non-automotive, cost-sensitive 24 V systems where 250 V margin suffices. |
| 1N4148W-7-F | VRRM = 100 V, trr = 4 ns, CT = 4.0 pF, SOD-123 | Insufficient voltage rating for 48 V bus; ultra-fast but not high-voltage capable | Use only in sub-30 V logic-level clamping where speed dominates voltage requirement. |
Compared with BAV21W-7-F and 1N4148W-7-F, the BAV5004LP-7B uniquely combines 400 V rating, AEC-Q101 qualification, and 2.5 pF capacitance-enabling direct deployment in automotive 48 V domains without derating or secondary protection.

FAQ
Is BAV5004LP-7B pin-compatible with standard SOD-123 or DO-35 diodes?
No. BAV5004LP-7B uses the X1-DFN1006-2 (1.0 mm × 0.6 mm) two-terminal surface-mount package, which is physically and thermally distinct from leaded SOD-123 or axial DO-35 packages. Pad layout, reflow profile, and thermal management must follow Diodes' recommended footprint-not legacy through-hole or larger SMD footprints.
What is the maximum allowable peak forward surge current for BAV5004LP-7B?
The non-repetitive peak forward surge current is 5.0 A for 1.0 µs and 3.0 A for 1.0 ms, as specified in the Absolute Maximum Ratings table. These values assume single-event conditions with adequate cooling between surges; repeated application requires derating per the power derating curve in Figure 1.
Does BAV5004LP-7B support bidirectional ESD protection?
No. BAV5004LP-7B is a unidirectional diode with anode and cathode terminals. For bidirectional ESD protection, a dual-diode array (e.g., D3V3F4U5-7) or TVS diode pair is required. This part functions only as a forward-conducting, reverse-blocking clamp.
How does the 357 °C/W thermal resistance impact PCB layout?
RθJA = 357 °C/W is measured on a standard FR-4 board with Diodes' recommended pad layout (documented in DS32181). To achieve rated 350 mW power dissipation, the copper area around pins must match the datasheet's suggested dimensions-reducing pad size or omitting thermal reliefs increases junction temperature and risks premature failure.
