Product details
Overview
BZG04-36TR from Vishay Semiconductors is a glass-passivated Zener diode designed for transient voltage suppression in power supply and signal line protection circuits. It features a 36 V standoff voltage, 40 V nominal breakdown voltage at 10 mA, 60.7 V clamping voltage at 4.9 A peak pulse current, 300 W non-repetitive surge power rating, and DO-214AC (SMA) package with 77 mg mass.
For engineers reviewing the BZG04-36TR datasheet, BZG04-36TR pinout, BZG04-36TR application, or BZG04-36TR equivalent, key selection criteria include clamping voltage margin versus protected IC VDD, surge current capability under 10/1000 µs waveform, thermal resistance to PCB copper area, junction temperature limit of 150 °C, and RoHS-compliant lead-free construction.
Technical Context
The BZG04-36TR operates as a unidirectional voltage clamp, leveraging avalanche breakdown to divert transient energy away from sensitive downstream circuitry. Its fast response time (≤1 ps) ensures effective suppression of ESD and lightning-induced surges before system damage occurs.
Thermal performance is defined by junction-to-lead resistance of 25 K/W and junction-to-ambient resistance ranging from 100–150 K/W depending on PCB mounting configuration (Al2O3 ceramic vs. epoxy-glass). Power derating follows linear reduction above 50 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VR) | 36 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold. |
| Breakdown Voltage (VBR) | 40 V min @ 10 mA - Precise Zener reference point used for tolerance-based design margining. |
| Clamping Voltage (VCL) | 60.7 V max @ 4.9 A - Peak voltage seen by protected circuit during 10/1000 µs surge; critical for IC overvoltage immunity. |
| Surge Power (PZSM) | 300 W - Non-repetitive peak power handling capability under standard lightning surge waveform. |
| Junction Temp Limit | 150 °C - Absolute maximum operating temperature; requires thermal design to avoid sustained exceedance. |
| Package | DO-214AC (SMA) - Surface-mount outline with 2.5 mm lead spacing; compatible with standard reflow profiles. |
| RoHS Compliance | Lead-free per 2002/95/EC - Meets EU directive; no exemption required for Pb content. |
Pinout & Package
DO-214AC (SMA) package: molded plastic body with axial leads trimmed and formed for surface mounting; cathode band marked on body; mechanical dimensions per Vishay Doc. 85594 Rev. 2.2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry during forward conduction | Connected to lower-potential node (e.g., GND or return path); enables bidirectional clamping when paired with another diode. |
| Cathode | Current exit during reverse breakdown | Connected to protected line (e.g., 36 V rail); conducts surge current to ground when transient exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable Zener voltage and low leakage (<5 µA at 36 V) across temperature and lifetime. |
| Fast response time ≤1 ps | Ensures clamping activation before nanosecond-scale ESD events propagate into IC inputs. |
| 300 W surge power rating | Supports IEC 61000-4-5 Level 4 (4 kV/2 Ω) surge testing without failure when properly heatsinked. |
| DO-214AC package | Provides 2.5 mm creepage/clearance and 1.5 kW/m·K thermal conductivity for reliable board-level integration. |
| 150 °C junction rating | Allows operation in high-temperature environments (e.g., automotive under-hood, industrial motor drives) with appropriate layout. |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A | Higher clamping voltage (64.8 V), larger SMB package (DO-214AA), 600 W surge rating | Better suited for higher-energy surges but less precise voltage control due to wider VBR tolerance | Select when surge energy exceeds 300 W and PCB space allows larger footprint |
| P6SMB36A | Same DO-214AA package, identical 36 V standoff, but 600 W PZSM and 5.8 A IPP | Lower thermal resistance (RthJA = 85 K/W typical) enables higher duty-cycle operation | Prefer when repeated surge exposure is expected and thermal management is constrained |
Compared with SMBJ36A and P6SMB36A, the BZG04-36TR offers tighter voltage tolerance (±2.5 % vs. ±5 %), lower clamping voltage (60.7 V vs. ≥64.8 V), and smaller DO-214AC footprint-making it optimal for space-constrained, precision-clamping designs where single-event surge energy stays within 300 W.

FAQ
What is the maximum clamping voltage of the BZG04-36TR under standard surge conditions?
The BZG04-36TR has a maximum clamping voltage of 60.7 V when subjected to a 10/1000 µs surge waveform at 4.9 A peak current. This value is measured per IEC 61000-4-5 test conditions and represents the highest voltage the protected circuit will experience during transient suppression. The BZG04-36TR maintains this clamping performance consistently due to its glass-passivated junction and low dynamic impedance.
Is the BZG04-36TR suitable for bidirectional transient protection?
No-the BZG04-36TR is a unidirectional Zener diode optimized for reverse-bias clamping only. For bidirectional protection, two BZG04-36TR devices must be connected in series opposition (anode-to-anode), or a dedicated TVS array like the SMAJ36CA should be selected. The BZG04-36TR's forward voltage is 1.2 V at 0.5 A, confirming its asymmetrical conduction behavior.
What is the thermal resistance from junction to ambient for the BZG04-36TR on a standard PCB?
When mounted on epoxy-glass hard tissue per Figure 1b in Vishay Doc. 85594, the BZG04-36TR exhibits a junction-to-ambient thermal resistance (RthJA) of 125 K/W. On Al2O3 ceramic substrate, RthJA improves to 100 K/W. These values directly impact power derating curves and must be applied when calculating safe operating area for repetitive surge conditions.
Does the BZG04-36TR meet automotive qualification standards?
The BZG04-36TR is not AEC-Q200 qualified, though it is widely used in automotive body electronics such as BCMs and lighting modules. Its 150 °C junction rating, lead-free construction, and robust surge capability align with many automotive subsystem requirements-but formal qualification requires additional stress testing per AEC-Q200. For AEC-Q200-compliant alternatives, consider the Automotive Grade SMBJ36A.
How does the BZG04-36TR's leakage current compare to other Zener diodes in its voltage class?
At its 36 V standoff voltage and 25 °C ambient, the BZG04-36TR specifies a maximum reverse leakage current (IR) of 5 µA-significantly lower than typical industry-standard Zeners (often 10–50 µA at same VR). This low leakage is enabled by glass passivation and supports high-impedance sensing nodes and battery-powered systems where quiescent current matters. The BZG04-36TR maintains this performance across its full operating temperature range.
