Product details
Overview
BZG04-13TR from Vishay Semiconductors is a glass-passivated Zener diode designed for transient voltage suppression in power rails and signal lines, with a nominal standoff voltage of 13 V, 22.9 V clamping voltage at 13.1 A peak pulse current, 300 W non-repetitive surge power rating, and DO-214AC (SMA) package for surface-mount reliability in industrial power supplies.
For engineers reviewing the BZG04-13TR datasheet, BZG04-13TR pinout, BZG04-13TR application, or BZG04-13TR 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 BZG04-13TR operates as a unidirectional voltage-clamping device with precise Zener breakdown at 15.3 V ±5 % (IZT = 25 mA), delivering fast response time ≤1 ps and low junction capacitance (785 pF at 0 V). Its glass-passivated junction ensures stable leakage current (IR ≤ 5 µA at VR = 13 V) and high reliability under repetitive transients.
Thermal design relies on defined mounting configurations: RthJA = 125 K/W when mounted per Fig. 1b on epoxy-glass hard tissue, and RthJL = 25 K/W for junction-to-lead conduction. Power derating follows linear reduction above Tamb = 50 °C, with Pdiss = 1.25 W at 50 °C and 3 W at 100 °C under specified thermal conditions.
Key Specifications

|---|---|
Use Scenario: Suppresses load-dump spikes (up to 120 V, 100 ms) and alternator ripple on 12 V rail feeding microcontrollers and sensors. IC Role / Device Role / Timing Role: Unidirectional transient voltage suppressor placed across input capacitor, clamping surges before they reach LDOs or MCU power pins. Use Value: Maintains 13 V standoff while limiting clamped voltage to 22.9 V, preserving 30 V-rated downstream components without derating. |
Use Scenario: Protects CAN transceiver supply lines against ISO 7637-2 Pulse 1 (−150 V, 2 Ω source) and Pulse 2a (25 V, 10 mΩ) transients. IC Role / Device Role / Timing Role: Standoff diode in parallel with supply rail, activated only during overvoltage events to divert surge current away from interface ICs. Use Value: 785 pF junction capacitance avoids signal integrity degradation on 500 kbps CAN bus, unlike higher-capacitance TVS alternatives. |
| Programmable Logic Controller (PLC) I/O Module | Telecom AC-DC Adapter Input Stage |
Use Scenario: Shields 24 V digital input circuits from field-wiring induced inductive kickback and ESD events per IEC 61000-4-2 Level 4. IC Role / Device Role / Timing Role: Primary clamping element on channel input, coordinated with series current-limiting resistor and optional RC filter. Use Value: 13.1 A peak surge current rating enables reliable handling of 1 kV/500 Ω EFT bursts without degradation after repeated stress. |
Use Scenario: Guards bridge rectifier output against line-switching transients and lightning-induced surges entering via AC mains. IC Role / Device Role / Timing Role: Secondary-side clamp on bulk capacitor node, complementing primary-side MOV and X/Y capacitors. Use Value: 300 W surge rating allows absorption of 6 kV/3 kA surges (per IEC 61643-11) without thermal runaway, supported by 150 °C max junction temperature. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener-based transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | Higher clamping voltage (21.5 V @ 13.3 A), lower Cj (550 pF), same DO-214AA package | Better suited for high-speed data lines due to lower capacitance; less margin for 24 V systems | Select SMBJ13A when lower parasitic capacitance is prioritized over tighter clamping voltage |
| P6SMB13A | Same clamping (21.5 V @ 13.3 A), higher PZSM (600 W), identical DO-214AA footprint | Higher surge endurance for infrequent but extreme transients (e.g., outdoor telecom); larger thermal mass | Choose P6SMB13A for mission-critical infrastructure where single-event survivability exceeds 300 W |
Compared with SMBJ13A and P6SMB13A, the BZG04-13TR offers tighter clamping (22.9 V vs. 21.5 V) and lower cost for general-purpose industrial use, while its DO-214AC package provides slightly better thermal resistance than DO-214AA variants under identical board layouts.

FAQ
What is the maximum clamping voltage of the BZG04-13TR under standard surge conditions?
The BZG04-13TR has a maximum clamping voltage of 22.9 V when subjected to a 10/1000 µs surge waveform at a peak current of 13.1 A. This value is measured per the Electrical Characteristics table in Vishay Document 85594 Rev. 2.2 and defines the upper voltage limit imposed on protected circuits during transient events. The BZG04-13TR maintains this clamping performance across its rated operating temperature range.
Is the BZG04-13TR suitable for bidirectional transient suppression?
No, the BZG04-13TR is a unidirectional Zener diode intended for reverse-biased operation only. It does not provide symmetrical clamping for both positive and negative transients. For bidirectional protection, a pair of BZG04-13TR devices in series opposition or a dedicated bidirectional TVS like SMAJ13CA would be required. The BZG04-13TR datasheet specifies parameters exclusively for unidirectional operation.
What is the thermal resistance from junction to ambient for the BZG04-13TR on a standard PCB layout?
The BZG04-13TR exhibits a junction-to-ambient thermal resistance (RthJA) of 125 K/W when mounted on epoxy-glass hard tissue per Figure 1b in the Vishay datasheet. This value assumes a specific copper pad layout and is critical for calculating junction temperature rise under sustained power dissipation. The BZG04-13TR's RthJA increases to 150 K/W on less thermally optimized boards (Fig. 1a).
Does the BZG04-13TR meet RoHS and lead-free requirements?
Yes, the BZG04-13TR is explicitly certified as lead (Pb)-free and compliant with RoHS Directive 2002/95/EC and WEEE Directive 2002/96/EC, as stated in the Vishay BZG04-Series datasheet (Document 85594 Rev. 2.2). The BZG04-13TR uses fully RoHS-compliant materials and plating, supporting environmentally regulated manufacturing without exemption requests.
What is the typical junction capacitance of the BZG04-13TR and how does it affect signal-line protection?
The BZG04-13TR has a typical junction capacitance of 785 pF at 0 V and 1 MHz, as specified in the Electrical Characteristics table. This capacitance limits its suitability for high-speed data lines (e.g., USB 2.0 or HDMI), where sub-100 pF is preferred, but remains appropriate for lower-frequency analog or power-rail protection. The BZG04-13TR's capacitance is confirmed at zero bias and decreases with increasing reverse voltage.
