Product details
Overview
BZG04-110TR3 from Vishay Semiconductors is a glass-passivated, high-reliability Zener diode designed for transient voltage suppression in power rails and signal lines. 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 (SMA) package. It is used in industrial power supply overvoltage protection circuits.
For engineers reviewing the BZG04-110TR3 datasheet, BZG04-110TR3 pinout, BZG04-110TR3 application, or BZG04-110TR3 equivalent, key selection criteria include clamping voltage under 10/1000 µs surge, thermal resistance to ambient (125 K/W on epoxy-glass hard tissue), junction temperature limit (150 °C), and RoHS-compliant lead-free construction.
Technical Context
The BZG04-110TR3 operates as a unidirectional voltage clamp with fast response time (≤1 ps), leveraging a glass-passivated PN junction for stable Zener characteristics and high surge tolerance. Its thermal design relies on low junction-to-lead resistance (25 K/W) and supports mounting on epoxy-glass or Al₂O₃ substrates for optimized RthJA.
It delivers precise voltage regulation across a wide operating temperature range (–65 °C to +150 °C), with tight breakdown voltage tolerance (min 124 V, typ 139 V at IZT = 5 mA) and low temperature coefficient (0.09 %/K). The device sustains 50 A peak forward surge current and maintains ≤153 pF junction capacitance at 0 V bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VR) | 110 V - Maximum reverse voltage before significant conduction begins; defines operating margin below clamping threshold. |
| Breakdown Voltage (V(BR)) | 124 V min at 5 mA - Ensures reliable turn-on during overvoltage events without premature triggering. |
| Clamping Voltage (VCL) | 185 V at 1.6 A (10/1000 µs) - Limits transient energy delivered to downstream circuitry during surge events. |
| Peak Surge Power (PZSM) | 300 W - Supports high-energy transients common in industrial AC line and motor drive applications. |
| Junction Capacitance (Cj) | 153 pF at 0 V, 1 MHz - Low enough to avoid signal integrity degradation in moderate-speed data lines. |
| Thermal Resistance (RthJA) | 125 K/W on epoxy-glass hard tissue - Determines safe power derating and PCB copper area requirements. |
| Junction Temperature Limit | 150 °C - Sets maximum allowable operating temperature for long-term reliability under sustained stress. |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, molded plastic case with axial leads trimmed and formed for reflow soldering. Approximate weight: 77 mg.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | High-impedance reference node | Connected to protected line; conducts when voltage exceeds V(BR); requires low-inductance trace routing. |
| Anode | Reference return path | Typically tied to system ground or lower-potential rail; must maintain low impedance to sustain clamping performance. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable Zener voltage over lifetime and improved moisture resistance vs. epoxy-passivated alternatives. |
| Fast response time ≤1 ps | Minimizes voltage overshoot during nanosecond-scale ESD or lightning-induced transients. |
| 300 W non-repetitive surge rating | Supports IEC 61000-4-5 Level 4 (4 kV) surge testing without degradation when properly heatsinked. |
| RoHS-compliant & lead-free | Meets EU Directive 2002/95/EC and WEEE 2002/96/EC; suitable for environmentally regulated industrial deployments. |

Applications
| Industrial Power Supply Protection | DC Motor Drive Snubbing |
|---|---|
Use Scenario: Protecting 110 V DC bus rails against switching transients generated by contactor bounce or relay de-energization. IC Role / Device Role / Timing Role: Unidirectional voltage clamp absorbing inductive kickback energy before it damages MOSFETs or controllers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener transient 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 PZSM, bidirectional configuration. | Designed for symmetric AC-line protection; requires external polarity handling for DC-only use. | Select SMBJ110A only if bidirectional surge immunity (e.g., telecom AC input) is required; BZG04-110TR3 offers tighter VZ tolerance and lower Cj for DC precision clamping. |
| P6SMB110A | Same DO-214AA package, 600 W PZSM, 187 V clamping, ±5% VZ tolerance vs. BZG04-110TR3's typical 139 V (no tolerance band stated). | Broader VZ distribution increases risk of inconsistent clamping onset across production units. | Choose BZG04-110TR3 where consistent breakdown voltage and low temperature coefficient (0.09 %/K) are critical for thermal-stable protection in variable-temperature environments. |
Compared with SMBJ110A and P6SMB110A, the BZG04-110TR3 provides superior voltage stability (0.09 %/K TC), lower junction capacitance (153 pF), and tighter typical breakdown (139 V), making it preferable for DC bus protection where clamping predictability and signal integrity matter more than peak surge rating.

FAQ
What is the maximum clamping voltage of the BZG04-110TR3 under standard surge conditions?
The BZG04-110TR3 has a maximum clamping voltage of 185 V when subjected to a 10/1000 µs surge waveform at 1.6 A peak current. This value is measured per the test condition specified in Vishay's Document Number 85594 Rev. 2.2 and reflects the device's ability to limit transient overvoltage to protect downstream components. The BZG04-110TR3 achieves this while maintaining low thermal resistance and stable Zener characteristics across its operating temperature range.
Is the BZG04-110TR3 suitable for bidirectional transient suppression?
No, the BZG04-110TR3 is a unidirectional Zener diode intended for DC or single-polarity transient suppression. Its electrical characteristics-including breakdown voltage, clamping behavior, and forward voltage-are defined only for reverse-biased operation. For bidirectional protection, a dedicated bidirectional TVS like SMBJ110A would be required. The BZG04-110TR3 must be oriented with cathode toward the protected line to function correctly.
What is the thermal resistance from junction to ambient for the BZG04-110TR3 on standard FR-4 PCB?
When mounted on epoxy-glass hard tissue (standard FR-4 PCB per Figure 1b in the datasheet), the BZG04-110TR3 exhibits a junction-to-ambient thermal resistance (RthJA) of 125 K/W. This value assumes recommended pad layout and no additional heatsinking. Derating curves in the datasheet show that power dissipation must be reduced above 50 °C ambient to stay within the 150 °C junction temperature limit. The BZG04-110TR3's RthJL of 25 K/W further supports effective heat transfer through the leads.
Does the BZG04-110TR3 meet RoHS and lead-free requirements?
Yes, the BZG04-110TR3 is explicitly certified as lead (Pb)-free and compliant with RoHS Directive 2002/95/EC and WEEE Directive 2002/96/EC, as confirmed in Vishay's datasheet Document Number 85594 Rev. 2.2. The device uses glass passivation instead of lead-based solder glass, and all materials are verified ozone-depleting-substance-free per Vishay's environmental policy. This makes the BZG04-110TR3 suitable for export-controlled and environmentally regulated industrial designs.
How does the BZG04-110TR3 compare to the BZG04-100TR3 in terms of clamping performance?
The BZG04-110TR3 clamps at 185 V (1.6 A, 10/1000 µs), whereas the BZG04-100TR3 clamps at 167 V (1.8 A, 10/1000 µs). The higher standoff voltage of the BZG04-110TR3 allows it to remain non-conductive at higher normal operating voltages-e.g., protecting a 110 V DC bus-while still limiting transients to a safe level. Both share identical DO-214AC packaging, thermal specs, and surge ratings, but the BZG04-110TR3's higher VR and V(BR) make it appropriate for systems with elevated nominal rail voltages.
