Product details
Overview
ESDZV5-1BF4 from STMicroelectronics is a bidirectional single-line TVS diode designed for ESD protection of high-speed data lines in space-constrained portable electronics. It delivers 7 V clamping voltage at 8 kV IEC 61000-4-2 contact discharge, 6–7.5 pF line capacitance at 1 MHz, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the ESDZV5-1BF4 datasheet, ESDZV5-1BF4 pinout, ESDZV5-1BF4 application, or ESDZV5-1BF4 equivalent, key selection criteria include ultra-low clamping performance under 8/20 µs transients, sub-8 pF capacitance for USB 2.0/MIPI compatibility, 0201 footprint constraints, and bidirectional snapback behavior with defined VH (4–4.6 V) and VTrig (5.8–10 V).
Technical Context
This device implements a silicon avalanche snapback structure optimized for fast ESD response (<30 ns clamping onset) and low dynamic resistance (0.18 Ω). Its bidirectional symmetry enables protection on AC-coupled or differential signal lines without polarity concerns.
The 0201 package integrates both anode and cathode terminals into a two-terminal surface-mount configuration, with no internal series impedance or RC network-functioning as a pure voltage-triggered clamp. Standoff voltage (VRM = 5.5 V max) and holding voltage (VH = 4–4.6 V) ensure reliable recovery after transient suppression.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCL (8 kV contact) | 7 V - clamps transients within safe margin for 5 V logic interfaces |
| CLINE @ 1 MHz | 6–7.5 pF - preserves signal integrity up to 480 Mbps (USB 2.0) |
| VTrig | 5.8–10 V - ensures turn-on before damage threshold of sensitive I/O cells |
| VH | 4–4.6 V - guarantees return to high-impedance state post-transient |
| RD | 0.18 Ω - minimizes voltage overshoot during high-current ESD events |
| IPP (8/20 µs) | 7 A - supports IEC 61000-4-2 Level 4 compliance (±18 kV contact) |
| Package | 0201 (0.6 × 0.3 mm) - enables placement adjacent to connectors or IC pads |
Pinout & Package
ESDZV5-1BF4 is a two-terminal bidirectional device in a 0201 monolithic package. No internal polarity or dedicated anode/cathode marking-the device functions identically regardless of orientation across the protected line.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode or Cathode (bidirectional) | Connected to protected signal line; symmetric conduction path |
| Terminal 2 | Cathode or Anode (bidirectional) | Connected to reference plane (GND or VCC); completes clamp loop |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD1E05U06DPYR | Unidirectional; 5.5 V standoff; 5.5 pF typical capacitance | Requires DC bias awareness; not suitable for AC-coupled lines | Select when protecting single-ended lines referenced to GND only |
| ESD9X5.0ST5G | Bidirectional; 5 V standoff; 12 pF capacitance; SOD-523 package | Larger footprint (1.3 × 0.8 mm); higher capacitance limits speed | Choose if board layout cannot accommodate 0201 or requires higher surge rating |
Compared with TPD1E05U06DPYR and ESD9X5.0ST5G, ESDZV5-1BF4 uniquely combines bidirectional operation, 0201 size, and sub-8 pF capacitance-making it optimal for miniaturized, high-speed differential interfaces where polarity-agnostic protection and minimal loading are mandatory.

FAQ
What is the maximum operating temperature for ESDZV5-1BF4?
The ESDZV5-1BF4 has a specified junction temperature range of –55 °C to +150 °C. This allows reliable operation in thermally demanding environments such as inside sealed smartphone chassis or near battery compartments, provided PCB thermal design maintains junction temperature within this limit during continuous operation and transient events.
Can ESDZV5-1BF4 be used on a 3.3 V I²C bus?
Yes-its 4–4.6 V holding voltage (VH) and 5.5 V maximum standoff voltage (VRM) ensure safe operation on 3.3 V buses. The device remains non-conductive during normal signaling and triggers only during ESD events exceeding ~5.8 V, preventing false triggering or leakage-induced bus contention.
Is ESDZV5-1BF4 compatible with lead-free reflow profiles?
Yes-it is qualified for standard lead-free reflow per IPC/JEDEC J-STD-020, with peak temperature up to 245 °C and 60–90 second time above liquidus. ST's recommended profile specifies 240–245 °C peak, ramp rates ≤3 °C/s, and controlled cooling to prevent solder joint fracture or package delamination.
Does ESDZV5-1BF4 require external biasing or series components?
No-ESDZV5-1BF4 is a passive, two-terminal device requiring no external bias, resistors, or capacitors. It connects directly across the protected line and reference (GND or VCC), leveraging intrinsic snapback characteristics for self-triggering and automatic recovery without auxiliary circuitry.
