Product details
Overview
HZS36-3LTA-E from Renesas Electronics is a silicon planar Zener diode optimized for low-noise voltage reference and stabilization in precision analog circuits, featuring a nominal zener voltage of 36.4–38.0 V at 0.5 mA test current, 300 Ω dynamic impedance, 400 mW power dissipation, and −55 to +175 °C storage temperature range. It is used in high-stability power supplies, instrumentation references, and sensor biasing where low noise and tight voltage tolerance are critical.
For engineers reviewing the HZS36-3LTA-E datasheet, HZS36-3LTA-E pinout, HZS36-3LTA-E application, or HZS36-3LTA-E equivalent, key selection criteria include zener voltage tolerance (±1.6 V), low noise performance (~1/3–1/10 of HZ series), thermal coefficient behavior near 36 V, and compatibility with 5 mm-pitch automated insertion processes.
Technical Context
This device operates as a two-terminal voltage reference using silicon planar junction technology, with zener breakdown mechanism dominant in its 36–38 V range. Its low leakage (<1 μA at VR = 27 V) and low dynamic impedance (300 Ω max at IZ = 0.5 mA) support stable regulation under light-load conditions.
The HZS36-3LTA-E exhibits a negative temperature coefficient near 36 V (≈ −0.06 %/°C per Fig.2), requiring thermal design consideration in high-precision references. It is rated for junction temperatures up to 200 °C and conforms to Renesas' Standard quality grade for industrial and office equipment applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 36.4–38.0 V at IZ = 0.5 mA - defines stable reference point for feedback loops and bias networks |
| Dynamic Impedance (rd) | ≤300 Ω at IZ = 0.5 mA - ensures minimal output voltage variation under load transients |
| Power Dissipation (Pd) | 400 mW at Ta = 25 °C - sets maximum continuous DC power handling on standard PCBs |
| Reverse Leakage (IR) | ≤1 μA at VR = 27 V - enables low-error operation in high-impedance reference dividers |
| Junction Temperature (Tj) | 200 °C maximum - supports reliable operation in thermally constrained enclosures |
| Storage Temperature | −55 to +175 °C - allows use in wide-environment industrial deployments without preconditioning |
| Noise Performance | ~1/3–1/10 of HZ-series diodes - reduces RMS noise contribution in audio, measurement, and ADC reference paths |
Pinout & Package
Package: MHD (JEITA code GRZZ0002ZC-A), axial-leaded, 2.0 mm diameter body, 26.0 mm length, 5 mm pitch compatible, mass ≈ 0.084 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener cathode terminal | Connected to higher potential node; reverse-biased operation requires positive voltage applied here relative to anode |
| 2 (Anode) | Zener anode terminal | Connected to circuit ground or lower potential; completes reverse-bias path for zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise zener structure | Diode noise reduced to ~1/3–1/10 of legacy HZ series - directly improves SNR in precision analog front-ends |

| High-power density package | 400 mW rating in compact MHD axial package - enables space-constrained board layouts without derating penalties |
| Automated assembly compatibility | 5 mm pitch lead spacing - supports high-throughput placement on SMT-compatible through-hole lines |
| Wide operating temperature margin | −55 to +175 °C storage range - ensures reliability across automotive under-hood, industrial control, and outdoor equipment |
Applications
| Industrial Power Supply Reference | Precision Sensor Biasing |
|---|---|

Use Scenario: Stabilizing feedback voltage in isolated DC-DC converters for PLC I/O modules. IC Role / Device Role / Timing Role: Two-terminal voltage reference providing fixed 36.4–38.0 V reference for error amplifier input. Use Value: Low dynamic impedance (≤300 Ω) minimizes loop gain variation; low noise prevents corruption of 16-bit ADC measurements downstream. |

IC Role / Device Role / Timing Role: Passive voltage reference establishing common-mode level for ratiometric bridge excitation. Use Value: Tight VZ tolerance (±1.6 V) and low leakage (<1 μA) ensure sub-0.1% full-scale error over temperature and time. |

Use Scenario: Providing clean reference for op-amp offset nulling and DAC output buffering in studio-grade preamps. IC Role / Device Role / Timing Role: Low-noise DC reference source decoupled from noisy power rails. Use Value: Noise reduction vs. HZ series directly lowers audible hiss floor; 400 mW rating supports robust thermal stability during long-duration recording sessions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor 1N4749A | Zener voltage 24 V (fixed), 200 mW rating, 20 Ω impedance - lower voltage, lower power, higher impedance than HZS36-3LTA-E | Suitable for 24 V systems only; not interchangeable in 36 V reference designs without circuit redesign | Select only if target voltage is 24 V and noise/impedance requirements are less stringent |
| Vishay BZX85C36 | Zener voltage 36 V (±5%), 1.3 W rating, 50 Ω impedance - wider tolerance, higher power, lower impedance, TO-226AA package | Requires larger PCB footprint; better for high-current shunt regulation but lacks HZS36-3LTA-E's low-noise optimization | Prefer when thermal headroom >400 mW is needed and noise is secondary to power handling |
Compared with 1N4749A and BZX85C36, the HZS36-3LTA-E delivers uniquely low noise and tighter voltage tolerance within its 36–38 V range while maintaining compatibility with high-speed automated insertion - making it optimal for precision analog systems where signal integrity outweighs raw power capacity.

FAQ
What is the exact zener voltage range specified for HZS36-3LTA-E?
The HZS36-3LTA-E has a guaranteed zener voltage range of 36.4 V to 38.0 V when tested at IZ = 0.5 mA and Ta = 25 °C, as confirmed in the Renesas REJ03G0166-0300 datasheet, page 3. This 1.6 V window reflects its precision grading for low-drift reference use, and the value is measured with DC test conditions per Note 1.
Does HZS36-3LTA-E support automated PCB assembly?
Yes, the HZS36-3LTA-E uses the MHD package with 5 mm lead pitch, explicitly stated in the "Ordering Information" section of the Renesas datasheet as suitable for high-speed automatic insertion. Its axial-leaded form factor and standardized dimensions (φD = 2.0 mm, L = 26.0 mm) comply with industry-standard pick-and-place and wave-solder tooling.
What is the maximum allowable reverse current before breakdown in HZS36-3LTA-E?
The HZS36-3LTA-E specifies a maximum reverse leakage current (IR) of 1 μA at VR = 27 V and Ta = 25 °C. This value is defined in the "Electrical Characteristics" table on page 3 of the Renesas datasheet and represents the upper limit of off-state conduction prior to entering zener breakdown region.
How does the noise performance of HZS36-3LTA-E compare to standard Zener diodes?
The HZS36-3LTA-E achieves approximately 1/3 to 1/10 the noise level of the legacy HZ series, as stated in the "Features" section on page 1 of the Renesas datasheet. This improvement stems from its silicon planar construction and process optimization - directly reducing broadband RMS noise in voltage reference paths without external filtering.
Is HZS36-3LTA-E rated for automotive applications?
No, the HZS36-3LTA-E is classified as a Standard quality grade device per Renesas' quality grading system (page 1, Note 7), intended for computers, office equipment, industrial robots, and test equipment - not for automotive or safety-critical systems. It lacks AEC-Q200 qualification and is not recommended for under-hood or chassis-control use without additional validation.
