Product details
Overview
1N5364BG from onsemi is a 5 W axial-lead Zener diode with nominal zener voltage of 33 V, ±5% tolerance, 40 Ω maximum zener impedance at 10 mA test current, and 0.5 mA maximum leakage current at 25.1 V. It operates across −65 °C to +200 °C and delivers stable voltage regulation in DC power supply reference and overvoltage protection circuits.
For engineers reviewing the 1N5364BG datasheet, pinout, applications, or equivalent options, this device is selected for precision low-power voltage clamping, analog circuit biasing, and industrial sensor excitation where tight zener tolerance and high surge robustness (144 A peak @ 8.3 ms) are required.
Technical Context
The 1N5364BG uses a silicon-oxide passivated junction for stable breakdown characteristics and low thermal drift. Its zener voltage is specified at IZT = 10 mA with guaranteed min/typ/max values of 31.35 V / 33 V / 34.65 V under JEDEC-standard test conditions.
It features Class 3 ESD immunity (>16 kV HBM), 180 W non-repetitive surge capability, and a junction-to-lead thermal resistance of 25 °C/W at 3/8″ lead length - enabling reliable operation without heatsinking in moderate ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 33 V nominal, ±5% tolerance - ensures predictable clamping within ±1.65 V across production lots |
| Power Dissipation (PD) | 5 W at TL = 25 °C - supports continuous regulation in compact PCB layouts with minimal derating up to 65 °C |
| Zener Impedance (ZZT) | 40 Ω max @ IZT = 10 mA - maintains low dynamic resistance for stable output under varying load currents |
| Leakage Current (IR) | 0.5 mA max @ VR = 25.1 V - minimizes standby power loss in high-impedance reference nodes |
| Surge Current (IRM) | 144 A peak @ 8.3 ms - withstands transient overvoltages from inductive switching or lightning-induced surges |
| Operating Temperature | −65 °C to +200 °C - suitable for under-hood automotive, downhole, and industrial environments |
| ESD Rating | Class 3 (>16 kV HBM) - survives handling and board-level electrostatic events without parameter shift |
Pinout & Package
1N5364BG is housed in an axial-lead, transfer-molded plastic package (Case 017AA, SURMETIC 40), with cathode identified by a band. Leads are solderable per J-STD-020, rated for 260 °C for 10 seconds at 1/16″ from case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference node | Connected to lower-potential side of regulated circuit; defines reverse-bias polarity for clamping |
| Cathode | Zener breakdown terminal / Regulation reference point | Connected to higher-potential rail; provides stable 33 V reference when reverse-biased above VZ |
Key Features
| Feature | Design Value |
|---|---|
| Pb-Free construction | RoHS-compliant packaging with verified solderability and corrosion resistance per JESD22-A112 |
| Tight zener tolerance | ±5% VZ guarantee eliminates need for post-assembly trimming in fixed-reference designs |
| High surge robustness | 180 W surge rating enables use as primary overvoltage clamp without external TVS staging |
| Low thermal resistance | 25 °C/W θJL allows direct lead-mounting to copper pours for passive thermal management |
| Wide temperature range | Full electrical specification maintained from −65 °C to +150 °C (DC), supporting extreme-environment deployments |
Applications
| Industrial Power Supply Reference | Automotive Sensor Biasing |
|---|---|
Use Scenario: Providing stable 33 V reference for op-amp comparators and ADC voltage dividers in programmable logic controllers. IC Role / Device Role / Timing Role: Zener diode operating in reverse breakdown to establish fixed reference potential independent of input ripple. Use Value: ±5% VZ tolerance and 40 Ω ZZT ensure <10 mV reference drift across 0–10 mA load variation and −40 °C to +85 °C ambient. |
Use Scenario: Biasing resistive temperature detectors (RTDs) and pressure transducers in engine control units. IC Role / Device Role / Timing Role: Precision voltage clamp regulating excitation current source against battery voltage fluctuations (9–16 V). Use Value: 144 A surge rating absorbs load-dump transients up to ISO 7637-2 Pulse 5a without degradation, eliminating need for secondary protection. |
| Overvoltage Protection Clamp | Programmable Current Source Reference |
Use Scenario: Protecting microcontroller I/O pins and analog front-ends from ESD and inductive kickback in motor drive boards. IC Role / Device Role / Timing Role: Shunt regulator conducting excess energy to ground when line voltage exceeds 33 V threshold. Use Value: Class 3 ESD rating (>16 kV HBM) and 180 W surge capacity enable single-device protection without series impedance or timing delays. |
Use Scenario: Setting reference voltage for constant-current LED drivers and laser diode bias circuits. IC Role / Device Role / Timing Role: Stable 33 V node defining feedback voltage for current-sense amplifier gain calibration. Use Value: Low 0.5 mA leakage at 25.1 V prevents error injection into high-impedance current-sense paths, preserving <0.5% accuracy. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5364B | Same electrical specs but SnPb lead finish; not RoHS-compliant | Restricted to legacy industrial or military programs exempt from Pb-free mandates | Select only if Pb-free compliance is waived and existing solder process requires SnPb wetting |
| BZX85C33 | 1.3 W rating, 30 Ω ZZT, 100 mA IZM; TO-204AA package | Lower power handling limits use to signal-level clamping, not power rail regulation | Choose for space-constrained PCBs where 5 W dissipation is unnecessary and axial leads are acceptable |
Compared with 1N5364B, the 1N5364BG offers identical regulation performance with Pb-free compliance; compared with BZX85C33, it delivers 3.8× higher power handling and superior surge robustness, making it suitable for primary rail protection rather than auxiliary signal conditioning.

FAQ
What is the zener voltage tolerance of the 1N5364BG?
The 1N5364BG has a zener voltage tolerance of ±5%, with minimum, nominal, and maximum values of 31.35 V, 33 V, and 34.65 V respectively at IZT = 10 mA and TA = 25 °C. This tolerance is guaranteed per JEDEC standard and applies to all units bearing the "B" suffix.
Can the 1N5364BG be used in surface-mount designs?
No, the 1N5364BG is an axial-lead device in Case 017AA (SURMETIC 40) and is not compatible with SMT reflow processes. It requires through-hole mounting with leads trimmed and formed per IPC-7351 guidelines. For SMT alternatives, consider the MMBZ52xx series or SMAZ33.
What is the maximum steady-state current the 1N5364BG can handle?
The maximum DC zener current (IZM) for the 1N5364BG is 150 mA, calculated as PD/VZ(min) = 5 W / 31.35 V. This value is confirmed in the Electrical Characteristics table on page 3 of the onsemi datasheet.
Does the 1N5364BG require a heatsink for 5 W operation?
No heatsink is required for 5 W operation at TL = 25 °C, as the 1N5364BG's junction-to-lead thermal resistance is 25 °C/W. With 3/8″ lead length to a copper plane, junction temperature remains within 150 °C limit. Derating begins above 25 °C at 40 mW/°C.
How does the 1N5364BG perform under transient surge conditions?
The 1N5364BG sustains up to 144 A peak surge current for 8.3 ms (180 W) without parametric shift or failure. This is validated per Figure 5 in the datasheet and enables direct use in ISO 7637-2 Pulse 5a-compliant automotive protection circuits.
