Product details
Overview
BZG04-110TR from Vishay Semiconductors is a glass-passivated, surface-mount Zener diode designed for high-energy transient voltage suppression in power supply and interface protection circuits. It features a 110 V standoff voltage, 124 V minimum breakdown voltage at 5 mA, 185 V clamping voltage at 1.6 A surge current, 300 W non-repetitive peak surge power rating, and DO-214AC (SMC) package with RoHS-compliant lead-free construction.
For engineers reviewing the BZG04-110TR datasheet, BZG04-110TR pinout, BZG04-110TR application, or BZG04-110TR equivalent, key selection criteria include clamping voltage margin relative to protected IC rails, thermal resistance under PCB layout constraints, surge current capability for IEC 61000-4-5 compliance, and junction capacitance impact on high-speed signal integrity.
Technical Context
The BZG04-110TR operates as a unidirectional voltage clamp in reverse-biased configuration, leveraging avalanche breakdown to divert transient energy away from sensitive downstream circuitry. Its fast response time (≤1 ps) ensures effective suppression of nanosecond-scale transients such as ESD and lightning-induced surges.
Thermal performance is defined by junction-to-lead resistance of 25 K/W and junction-to-ambient resistance ranging from 100 K/W (on Al₂O₃ ceramic) to 150 K/W (on epoxy-glass PCB), directly impacting sustained power handling and reliability under repeated surge events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VR) | 110 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold |
| Breakdown Voltage (V(BR)) | 124 V min @ 5 mA - Ensures reliable conduction onset during overvoltage events without premature triggering |
| Clamping Voltage (VCL) | 185 V @ 1.6 A - Peak voltage seen by protected circuit during 10/1000 µs surge; critical for IC survivability |
| Surge Power (PZSM) | 300 W - Non-repetitive energy absorption capacity for transient immunity per IEC 61000-4-5 Level 4 |
| Junction Capacitance | 153 pF @ 0 V - Limits use in >10 MHz signal paths due to capacitive loading and bandwidth reduction |
| Package | DO-214AC (SMC) - Standardized SMD outline enabling automated placement and thermal pad compatibility |
Pinout & Package
DO-214AC (SMC) package: molded plastic body with two coplanar J-bend leads; cathode indicated by band; typical weight 77 mg; recommended footprint per Vishay Fig. 1b on epoxy-glass PCB.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A | Higher clamping voltage (187 V vs. 185 V), same DO-214AA package, 600 W PPK rating | Designed for higher-energy surges but exhibits greater voltage overshoot during fast transients | Select when system-level surge test margin requires >300 W headroom and layout allows larger footprint |
| P6SMB110A | Same clamping voltage (185 V), DO-214AA package, 600 W PPK, higher IR (1 µA vs. 5 µA) | Lower leakage enables use in ultra-low-power standby circuits where BZG04-110TR's 5 µA may cause drift | Prefer for battery-backed systems requiring sub-µA standby leakage; verify thermal derating on same PCB |
Compared with SMBJ110A and P6SMB110A, the BZG04-110TR offers tighter clamping tolerance and lower leakage at 110 V standoff, making it optimal for precision power rail protection where voltage margin and quiescent current are critical design constraints.

FAQ
What is the maximum clamping voltage of the BZG04-110TR under standard IEC 61000-4-5 test conditions?
The BZG04-110TR has a maximum clamping voltage of 185 V when subjected to a 10/1000 µs surge pulse at 1.6 A peak current, as specified in the Vishay BZG04-Series datasheet (Doc. #85594, Rev. 2.2). This value is measured at Tj = 25 °C and defines the upper voltage limit imposed on protected circuitry during standardized surge testing. The BZG04-110TR maintains this clamping performance consistently across its rated temperature range.
Does the BZG04-110TR meet RoHS and lead-free requirements?
Yes, the BZG04-110TR is a lead (Pb)-free component and complies with the EU RoHS Directive 2002/95/EC and WEEE Directive 2002/96/EC, as confirmed in the official Vishay BZG04-Series datasheet. All materials and plating processes used in the BZG04-110TR manufacturing meet the maximum concentration limits for restricted substances, including cadmium, mercury, hexavalent chromium, polybrominated biphenyls (PBB), and polybrominated diphenyl ethers (PBDE).
What is the thermal resistance from junction to ambient for the BZG04-110TR when mounted on an epoxy-glass PCB?
When mounted on an epoxy-glass hard tissue PCB per Vishay Figure 1b, the BZG04-110TR exhibits a junction-to-ambient thermal resistance (RthJA) of 125 K/W. This value assumes standard land pattern and copper area; actual RthJA will increase with smaller pads or reduced copper pour. For thermal design, the BZG04-110TR's junction-to-lead resistance remains fixed at 25 K/W regardless of board layout.
Can the BZG04-110TR be used in bidirectional transient protection configurations?
No, the BZG04-110TR is a unidirectional Zener diode intended for reverse-biased clamping only. It lacks symmetrical breakdown characteristics required for bidirectional protection. For AC or dual-polarity signal lines, a pair of BZG04-110TR devices in series opposition or a dedicated bidirectional TVS like SMAJ110A would be required. Using a single BZG04-110TR in forward bias provides only 1.2 V clamping, insufficient for most transient scenarios.
What is the typical junction capacitance of the BZG04-110TR and how does it affect high-frequency signal lines?
The BZG04-110TR has a typical junction capacitance of 153 pF measured at 0 V and 1 MHz, as stated in the Vishay BZG04-Series datasheet. This capacitance introduces signal attenuation and phase shift above ~1 MHz, making the BZG04-110TR unsuitable for protecting high-speed digital buses (e.g., USB 2.0, HDMI) or RF front-ends. For such applications, low-capacitance TVS devices (<5 pF) or specialized ESD arrays should be selected instead of the BZG04-110TR.
