Product details
Overview
HZS36-1LTD-E from Renesas Electronics is a silicon planar Zener diode optimized for low-noise voltage regulation in precision analog and stabilized power supply circuits, with a nominal zener voltage of 34.2–35.7 V, 400 mW power dissipation, and dynamic resistance of 33.0 Ω at 0.5 mA test current. It features low leakage, low zener impedance, and is qualified for industrial-grade applications including test equipment and office electronics.
For engineers reviewing the HZS36-1LTD-E datasheet, HZS36-1LTD-E pinout, HZS36-1LTD-E application, or HZS36-1LTD-E equivalent, key selection criteria include its 34.2–35.7 V zener voltage range, 33.0 Ω dynamic resistance at 0.5 mA, −55 to +175 °C storage temperature rating, 200 °C junction temperature limit, and suitability for 5 mm-pitch high-speed automatic insertion in PCB assembly.
Technical Context
This device operates as a two-terminal voltage reference using silicon planar Zener breakdown, delivering stable regulation under reverse bias with minimal noise-approximately 1/3–1/10 lower than the legacy HZ series. Its low dynamic resistance (33.0 Ω) and tight zener voltage tolerance support accurate voltage clamping in feedback loops and reference circuits.
The HZS36-1LTD-E is designed for DC operation only, with absolute maximum ratings defined at Ta = 25 °C. Its thermal performance is characterized up to 200 °C junction temperature, and it complies with Renesas' Standard quality grade for non-safety-critical industrial applications such as office equipment and test instrumentation.

Use Scenario: Stabilizing +36 V rail in programmable logic controller (PLC) I/O modules. IC Role / Device Role / Timing Role: Zener diode provides fixed reference voltage for op-amp-based current sensing and DAC output buffering. Use Value: 34.2–35.7 V zener range matches nominal 36 V supply with margin for ripple rejection; 33.0 Ω rd ensures <±10 mV regulation error over 1–10 mA load swing. |
Use Scenario: Generating stable reference for 16-bit SAR ADC in automated test equipment. IC Role / Device Role / Timing Role: Low-noise Zener establishes clean 35 V reference for ADC driver stage and gain calibration circuitry. Use Value: Noise reduction vs. HZ series improves effective resolution by ≥1 LSB; ≤1 μA leakage avoids reference node loading errors. |
| DC-DC Converter Feedback | Overvoltage Protection Clamp |
|
Use Scenario: Voltage-setting element in isolated flyback converter feedback loop. IC Role / Device Role / Timing Role: Zener diode sets output voltage threshold via optocoupler bias network. Use Value: Tight 34.2–35.7 V tolerance enables ±1.5% output accuracy; 400 mW Pd handles transient energy during startup overshoot. |
Use Scenario: Clamping transient spikes on 36 V CAN bus power line in automotive diagnostic tools. IC Role / Device Role / Timing Role: Fast-acting Zener shunts overvoltage events above 36 V to protect downstream LDOs and microcontrollers. Use Value: 200 °C Tj rating withstands repeated surge stress; low rd limits clamping voltage rise to <37 V at 100 mA surge. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5365BRLG | Zener voltage 36 V (nominal), 5 W power rating, DO-201AD package, 35 Ω rd at 100 mA | Higher power handling but larger footprint and higher leakage (>5 μA); suited for high-current clamp, not low-noise reference | Select when surge energy absorption >1 J is required; avoid where low noise or space-constrained layout is critical |
| BZX85C36-TR | Zener voltage 36 V (34.2–37.8 V), 1.3 W, DO-41 package, 60 Ω rd at 5 mA | Higher dynamic resistance and wider voltage tolerance reduce regulation precision; lower cost but no low-noise optimization | Acceptable for basic voltage limiting; not recommended for precision analog or noise-sensitive signal chains |
Compared with HZS36-1LTD-E, the 1N5365BRLG offers greater surge robustness but sacrifices PCB area and noise performance, while the BZX85C36-TR trades regulation accuracy and noise for cost and availability-making HZS36-1LTD-E the optimal choice for industrial-grade low-noise reference design.

FAQ
What is the exact zener voltage range specified for HZS36-1LTD-E?
The HZS36-1LTD-E has a guaranteed zener voltage range of 34.2 V to 35.7 V when tested at IZ = 0.5 mA and Ta = 25 °C. This range reflects the "-1L" variant designation within the HZS-L Series and is confirmed in the Renesas REJ03G0166-0300 datasheet, page 3. The HZS36-1LTD-E is not rated for 36.0 V nominal; design margins must accommodate this min/max spread.
Does HZS36-1LTD-E support surface-mount assembly?
No, the HZS36-1LTD-E uses the MHD axial-leaded package (JEITA code GRZZ0002ZC-A) with 2.0 mm body diameter and 26.0 mm length, designed exclusively for through-hole mounting and 5 mm-pitch high-speed automatic insertion. It is not compatible with reflow or pick-and-place SMT processes. For SMT alternatives, consult Renesas' HZS-L SMD variants or equivalent Zener arrays.
What is the maximum reverse leakage current for HZS36-1LTD-E?
The maximum reverse leakage current (IR) for HZS36-1LTD-E is 1 μA, measured at VR = 2.0 V and Ta = 25 °C. This low leakage is critical for high-impedance reference nodes and battery-powered systems where standby current must be minimized. The value is explicitly listed in the Electrical Characteristics table on page 2 of the REJ03G0166-0300 datasheet.
Is HZS36-1LTD-E qualified for automotive applications?
No, the HZS36-1LTD-E is classified as Renesas "Standard" quality grade, intended for computers, office equipment, test instruments, and industrial robots-not transportation or safety-critical systems. It lacks AEC-Q200 qualification or automotive temperature range certification. For automotive-grade Zeners, consider Renesas' HZS-A series or equivalents qualified to AEC-Q200 Grade 2 (−40 to +105 °C).
How does the noise performance of HZS36-1LTD-E compare to standard Zener diodes?
The HZS36-1LTD-E delivers approximately 1/3 to 1/10 the noise level of the legacy HZ series Zeners, as stated in the Features section of the REJ03G0166-0300 datasheet. This low-noise characteristic results from optimized silicon planar structure and process control, making it suitable for precision analog circuits such as ADC references and low-distortion audio power supplies where voltage reference noise directly impacts SNR.
