Product details
Overview
BZW04P53-E3/73 from Vishay General Semiconductor is a bi-directional TransZorb® transient voltage suppressor (TVS) diode designed for robust overvoltage protection in signal and power lines. It features a 53.0 V stand-off voltage (VWM), 85.0 V maximum clamping voltage (VC) at 4.7 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) capability with a 10/1000 μs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and telecom line protection.
For engineers reviewing the BZW04P53-E3/73 datasheet, BZW04P53-E3/73 pinout, BZW04P53-E3/73 application, or BZW04P53-E3/73 equivalent, key selection criteria include its DO-204AL (DO-41) package compatibility, AEC-Q101 qualification for automotive use, low 0.104 %/°C temperature coefficient of breakdown voltage, and verified bi-directional surge handling up to 4.7 A without polarity marking.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, with identical electrical characteristics in forward and reverse directions. Its glass-passivated junction ensures stable breakdown behavior and fast response time (<1 ns), while the 10/1000 μs surge rating reflects standardized lightning and inductive-switching transient immunity per ANSI/IEEE C62.35.
The device is rated for continuous power dissipation of 1.5 W on an infinite heatsink at 75 °C lead temperature and supports operating junction temperatures from –55 °C to +175 °C. Its low incremental surge resistance enables effective clamping during repetitive transients, and the absence of polarity marking confirms its bi-directional construction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 53.0 V - Maximum continuous working voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (min/max) | 58.9 V / 68.2 V at 1 mA - Verified breakdown range ensures consistent turn-on across production lots and temperature. |
| VC @ IPPM | 85.0 V at 4.7 A - Clamping voltage under full-rated 10/1000 μs surge; determines protected circuit's maximum transient exposure. |
| PPPM | 400 W - Peak pulse power handling with 0.01 % duty cycle; validates suitability for infrequent but high-energy transients. |
| ID @ VWM | 1.0 μA - Reverse leakage at stand-off voltage; ensures minimal standby power loss and signal integrity in high-impedance paths. |
| TJ max. | +175 °C - Maximum junction temperature; supports operation in under-hood automotive and industrial environments. |
| Temp. Coeff. | 0.104 %/°C - Temperature coefficient of VBR; enables predictable voltage shift over temperature for precision protection design. |
Pinout & Package
Package: DO-204AL (DO-41), axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating. Matte tin-plated leads comply with J-STD-002 and JESD22-B102 solderability standards. Bi-directional configuration means no cathode band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional surge conduction path | No polarity distinction - either lead serves as input/output terminal; enables placement flexibility in AC-coupled or floating lines. |
| Lead 1 / Lead 2 | Current-carrying terminals | Both leads conduct surge current equally in either direction; requires no orientation check during PCB assembly. |
Key Features
| Feature | Design Value |

IC Role / Device Role / Timing Role: Standoff protector on 24 V DC input lines, absorbing ±1 kV EFT bursts and 0.5 J surges without latch-up or parametric shift. Use Value: Enables >100,000 surge cycles at rated IPPM due to low incremental resistance and thermal robustness up to +175 °C junction temperature. |
| Telecom Line Interface | Consumer Power Adapter Input |
Use Scenario: Secondary-side transient suppression on Ethernet PHY power rails and RS-485 data lines in network switches and base stations. IC Role / Device Role / Timing Role: Fast-response bi-directional clamp parallel to LDO or DC-DC converter input, triggered within <1 ns to limit voltage excursion during lightning-induced surges.

IC Role / Device Role / Timing Role: Primary clamping element across bridge rectifier output or bulk capacitor, diverting surge current away from downstream switching MOSFETs and controllers. Use Value: Provides 400 W peak pulse rating with 1.5 W steady-state dissipation - enabling compact layout without external heatsinking in space-constrained adapters. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ53A-E3/52 | DO-214AA package; 53.0 V VWM; 87.1 V VC @ 4.6 A; 600 W PPPM | Higher peak power but larger footprint; lower thermal resistance due to surface-mount construction | Preferred where board space allows SMT and higher surge margin is required beyond 400 W |
| P6KE56A | DO-15 package; 56.0 V VWM; 93.6 V VC @ 4.3 A; 600 W PPPM; unidirectional only | Requires polarity-aware placement; higher clamping voltage reduces protected IC margin | Consider only when unidirectional protection suffices and legacy through-hole DO-15 footprint must be retained |
Compared with SMBJ53A-E3/52 and P6KE56A, the BZW04P53-E3/73 offers tighter clamping (85.0 V vs. ≥87.1 V), AEC-Q101 qualification not found in P6KE56A, and axial DO-41 compatibility ideal for high-reliability through-hole designs where automated optical inspection of polarity is impractical.

FAQ
What is the clamping voltage of BZW04P53-E3/73 under maximum rated surge current?
The BZW04P53-E3/73 has a maximum clamping voltage (VC) of 85.0 V when subjected to its rated peak pulse current (IPPM) of 4.7 A using the standard 10/1000 μs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuitry during transient events. The BZW04P53-E3/73 maintains this clamping performance across its specified operating temperature range.
Is BZW04P53-E3/73 suitable for automotive applications?
Yes, BZW04P53-E3/73 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction includes glass-passivated junctions, DO-204AL packaging compliant with UL 94 V-0, and guaranteed operation from –55 °C to +175 °C junction temperature - meeting requirements for engine control, body electronics, and ADAS sensor interfaces. The BZW04P53-E3/73 E3 suffix also satisfies RoHS and JESD201 Class 1A whisker testing.
How does the bi-directional nature of BZW04P53-E3/73 affect PCB layout?
The BZW04P53-E3/73 is inherently bi-directional with no polarity marking, so either lead may connect to either side of the protected line - eliminating orientation constraints during placement and simplifying automated assembly. This symmetry avoids risk of misplacement in AC-coupled, differential, or floating circuits. The BZW04P53-E3/73's DO-41 axial package further supports manual rework and high-voltage creepage spacing in through-hole layouts.
What is the maximum steady-state power dissipation for BZW04P53-E3/73?
The BZW04P53-E3/73 has a maximum power dissipation (PD) of 1.5 W when mounted on an infinite heatsink at a lead temperature (TL) of 75 °C, per Figure 5 in the Vishay datasheet. Derating is required above TL = 75 °C, with zero dissipation allowed at TL = 175 °C. This rating applies to continuous DC or low-frequency conditions - not transient surge events, where the 400 W PPPM rating governs short-duration energy handling. The BZW04P53-E3/73's thermal design supports reliable operation in sealed enclosures with limited airflow.
Does BZW04P53-E3/73 have a specified junction capacitance?
No junction capacitance (CJ) value is specified for BZW04P53-E3/73 in the official Vishay datasheet (Document Number: 88316). While Figure 4 shows typical CJ curves for the broader BZW04P family, no discrete point is given for the 53 V variant. For high-speed data line protection (e.g., USB, HDMI), designers should verify signal integrity via simulation or measurement, as the BZW04P53-E3/73's primary role remains high-energy transient suppression rather than RF filtering. The BZW04P53-E3/73 remains optimal for DC and low-frequency power/signal rails where capacitance impact is negligible.
