Product details
Overview
BZA462A from Nexperia is a quadruple ESD transient voltage suppressor diode in SOT457 (SC-74) package, configured as common-anode for 4-line I/O protection at 6.2 V working voltage, with 15 kV IEC 1000-4-2 ESD rating, 9 V clamping voltage at 2.66 A peak pulse current, and 24 W peak reverse power dissipation - used in USB, HDMI, and parallel bus interfaces of computing peripherals.
For engineers reviewing the BZA462A datasheet, BZA462A pinout, BZA462A application, or BZA462A equivalent, key selection criteria include common-anode quad-channel layout, low 110 pF capacitance at 4 V reverse bias, 300 Ω differential resistance, non-clamping range (−0.5 to 6.2 V), and thermal resistance of 125 K/W junction-to-soldering-point.
Technical Context
The BZA462A integrates four monolithic Zener-based TVS diodes on a single silicon die, sharing two anode terminals (pins 2 and 5) and routing cathodes individually (pins 1, 3, 4, 6). Its clamping behavior is defined by peak pulse conditions (tp = 1 ms, square wave), not DC operation.
It operates within a non-clamping window from −0.5 V to 6.2 V, enabling signal integrity preservation below the breakdown threshold; above 6.2 V, it enters avalanche conduction with 9 V clamping at 2.66 A, limiting transient energy via 24 W peak power dissipation capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VZ) | 6.2 V nominal at IZ = 1 mA - defines ESD trigger threshold for 4-bit data lines |
| Clamping Voltage (VZSM) | 9 V at IZSM = 2.66 A, tp = 1 ms - limits transient overshoot during 15 kV contact discharge |
| Diode Capacitance (Cd) | 110 pF at VR = 4 V, f = 1 MHz - preserves signal rise time in high-speed digital interfaces |
| Differential Resistance (rdif) | 300 Ω at IZ = 1 mA - determines dynamic impedance during low-energy transients |
| ESD Rating | >15 kV per IEC 1000-4-2 - qualifies for Level 4 system-level ESD immunity testing |
| Thermal Resistance (Rth j-s) | 125 K/W junction-to-soldering point - governs derating above 60 °C ambient (720 mW max at Ts = 60 °C) |
Pinout & Package
SOT457 (SC-74) surface-mount package: 6-lead, plastic, gull-wing leads; 3.1 mm × 2.7 mm body, 1.1 mm height, 0.95 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 | Protected line 1 output node - connects to I/O trace before connector |
| 2 | Common Anode A | Anode tie-point for diodes 1 & 2 - routed to local ground plane with minimal inductance |
| 3 | Cathode 2 | Protected line 2 output node - enables dual-channel protection in compact layout |
| 4 | Cathode 3 | Protected line 3 output node - supports parallel bus or multi-lane interface |
| 5 | Common Anode B | Anode tie-point for diodes 3 & 4 - electrically isolated from pin 2 to reduce crosstalk |
| 6 | Cathode 4 | Protected line 4 output node - completes quad-channel ESD path without external components |
Key Features
| Feature | Design Value |
|---|---|
| Quad-channel common-anode architecture | Four independent ESD paths share only two anode terminals - reduces PCB footprint vs discrete diodes |
| Low clamping voltage (9 V @ 2.66 A) | Ensures downstream logic ICs (e.g., 5 V tolerant microcontrollers) remain within safe operating voltage |
| 110 pF capacitance at 4 V reverse bias | Minimizes signal distortion on 10–50 Mbps digital buses (e.g., PS/2, parallel printer port) |
| Non-clamping range (−0.5 to 6.2 V) | Prevents interference with normal signal swing in 0–5 V TTL/CMOS systems |
Applications
| USB 2.0 Data Lines | HDMI DDC Channel |
|---|---|
Use Scenario: Protection of D+ and D− lines against ESD events during cable insertion/removal in host/peripheral ports. IC Role / Device Role / Timing Role: Quad-channel TVS suppresses ±15 kV contact discharge while maintaining <110 pF loading on 480 Mbps differential pair. Use Value: Prevents latch-up or gate oxide damage in USB transceivers without degrading eye diagram integrity. | Use Scenario: Shielding I²C-based Display Data Channel (DDC) pins (SCL/SDA) from ESD in monitor docking stations. IC Role / Device Role / Timing Role: Dual-cathode suppression on 3.3 V open-drain bus - leverages common-anode configuration for shared ground return. Use Value: Maintains I²C timing margins (rise time <1000 ns) while clamping transients to <9 V. |
| Parallel Printer Port | Industrial Keypad Interface |
Use Scenario: Safeguarding 8-bit bidirectional data bus and control signals (STROBE, ACK) in legacy LPT connections. IC Role / Device Role / Timing Role: Four cathodes protect four critical lines (e.g., D0–D3); dual anodes allow separate grounding for noise isolation. Use Value: Enables robust operation in factory-floor environments where 8 kV air discharge is common. | Use Scenario: ESD hardening of membrane keypad scan lines connected to microcontroller GPIOs in medical devices. IC Role / Device Role / Timing Role: One BZA462A protects four row/column lines - each cathode tied to a GPIO, anodes grounded near MCU VSS. Use Value: Eliminates false keypresses caused by ESD-induced MCU reset or input latch-up. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel ESD suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESDA6V1SC6 | Lower clamping voltage (6.5 V @ 1 A), higher capacitance (180 pF @ 0 V), same SOT457 package | Better for 3.3 V I/O but unsuitable for 5 V buses due to tighter clamping margin | Select when protecting low-voltage, low-speed interfaces where sub-7 V clamping is required |
| TPD4E001DQAR | Higher ESD rating (±15 kV IEC), lower capacitance (5.5 pF @ 0 V), different 6-pin SON package | Superior for high-speed USB 3.0 or MIPI - but requires re-layout due to non-SOT457 footprint | Choose for new designs targeting >1 Gbps data rates; avoid for drop-in replacement in legacy SOT457 layouts |
Compared with ESDA6V1SC6 and TPD4E001DQAR, the BZA462A offers balanced performance for 5 V-tolerant, medium-speed interfaces (≤50 Mbps) with proven manufacturability in SOT457-reflow processes and cost-effective quad-channel integration.

FAQ
What is the maximum peak pulse current the BZA462A can handle?
The BZA462A supports a non-repetitive peak reverse current (IZSM) of 2.66 A under 1 ms square-wave pulse conditions, corresponding to its 24 W peak power rating at VZSM = 9 V. This value is validated per IEC 61000-4-5 waveform definitions and applies per diode channel.
Can the BZA462A be used for bidirectional signal lines?
No - the BZA462A is unidirectional with common-anode configuration, designed for suppression of positive transients on cathode-connected signal lines referenced to ground. For bidirectional protection, a back-to-back diode array or dedicated bidirectional TVS (e.g., PESD5V0S1BA) is required.
How does the dual-common-anode structure affect PCB layout?
Pins 2 and 5 serve as separate anode terminals for two diode pairs, allowing independent grounding paths to minimize mutual inductance and crosstalk. Layout best practice requires short, direct traces from each anode to a low-inductance ground plane - never daisy-chained or shared with other signal returns.
Is the BZA462A compliant with RoHS and REACH regulations?
Yes - the BZA462A is manufactured by Nexperia in accordance with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free terminations (Pb-free, SnAgCu solder compatible) and halogen-free molding compound, certified per Nexperia's standard product compliance documentation.
