Product details
Overview
HZS36-1TD-E from Renesas Electronics is a silicon planar Zener diode designed for precision voltage regulation in stabilized power supplies, featuring a nominal zener voltage of 36.4–38.0 V at 2 mA test current, 400 mW maximum power dissipation, and low dynamic resistance of 140 Ω, commonly deployed in industrial power rail clamping and reference circuits.
For engineers reviewing the HZS36-1TD-E datasheet, HZS36-1TD-E pinout, HZS36-1TD-E application, or HZS36-1TD-E equivalent, key selection criteria include zener voltage tolerance (±2.7% at 36.4–38.0 V), temperature coefficient (−0.06 %/°C), junction temperature rating (200°C), and MHD package compatibility with 5 mm-pitch automated insertion.
Technical Context
This device operates as a two-terminal voltage reference using avalanche breakdown in a planar-diffused silicon junction, optimized for DC-stabilized supply rails where tight voltage tolerance and low dynamic impedance are required. It exhibits a negative temperature coefficient of −0.06 %/°C and maintains stable regulation across ambient temperatures up to 125°C before derating begins.
The HZS36-1TD-E is rated for 2 mA zener test current and supports reverse leakage ≤1 µA at VR = 0.5×VZ, enabling low-power biasing in precision analog circuits. Its 400 mW power rating is thermally limited by junction-to-ambient thermal resistance inherent to the MHD package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 36.4–38.0 V at IZ = 2 mA - defines regulated output voltage range under nominal bias |
| Dynamic Resistance (rd) | 140 Ω max at IZ = 2 mA - determines load regulation sensitivity and ripple rejection |
| Power Dissipation (Pd) | 400 mW max at Ta = 25°C - sets maximum continuous DC power handling before thermal derating |
| Junction Temperature (Tj) | 200°C - enables operation in high-temperature industrial environments with appropriate PCB copper area |
| Reverse Leakage (IR) | ≤1 µA at VR = 18.2 V - ensures minimal quiescent current in standby or low-power modes |
| Temperature Coefficient (γZ) | −0.06 %/°C - quantifies voltage drift over temperature; critical for stable references across −55°C to +125°C |
Pinout & Package
Package: MHD (JEITA code GRZZ0002ZC-A), molded plastic case with axial leads, 2.0 mm diameter, 26.0 mm body length, 5 mm lead pitch, 0.4 mm lead diameter, 0.084 g typical mass. Designed for high-speed automatic insertion on 5 mm-pitch PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener cathode terminal | Connected to higher potential node; marked with lake-blue band; carries regulated output voltage |
| 2 (Anode) | Zener anode terminal | Connected to lower potential (typically ground or return); completes reverse-biased conduction path |
Key Features
| Feature | Design Value |
|---|---|
| Low dynamic impedance | 140 Ω max ensures <1% output voltage shift under ±1 mA load variation at 36–38 V |
| Wide zener voltage range coverage | Part of HZS Series spanning 1.6–38 V enables single-supplier sourcing across multiple rail voltages |
| High junction temperature rating | 200°C Tj allows reliable operation in enclosed industrial enclosures without forced cooling |
| Low leakage current | ≤1 µA at half-rated voltage minimizes standby power loss in battery-backed or energy-sensitive systems |
| Automated insertion compatibility | MHD package with 5 mm pitch supports high-throughput SMT-compatible through-hole assembly lines |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4749A (ON Semiconductor) | Zener voltage 24 V, Pd = 1 W, DO-41 package, rd = 10 Ω - higher power but lower voltage grade | Not suitable for 36 V rail clamping; requires redesign for voltage level and thermal layout | Select only if 24 V regulation and higher power margin are required; not drop-in for HZS36-1TD-E |
| BZX85C36 (Nexperia) | Zener voltage 36 V ±5%, Pd = 1.3 W, DO-41, rd = 60 Ω - wider tolerance, lower impedance, larger package | Acceptable for non-critical 36 V references but lacks −0.06 %/°C tempco and MHD insertion compatibility | Prefer for cost-sensitive, non-automated assembly where tighter voltage tolerance is not required |
Compared with 1N4749A and BZX85C36, the HZS36-1TD-E offers superior voltage tolerance (±2.7% vs. ±5%), MHD package optimization for automated insertion, and a documented −0.06 %/°C temperature coefficient-making it preferred for industrial-grade 36–38 V reference and clamping where precision and manufacturability are jointly prioritized.

FAQ
What is the exact zener voltage range specified for HZS36-1TD-E?
The HZS36-1TD-E has a guaranteed zener voltage range of 36.4 V to 38.0 V when tested at IZ = 2 mA and Ta = 25°C, corresponding to Grade "-3" in the HZS36 family per Renesas datasheet REJ03G0184-0500 Rev.5.00. This ±2.7% tolerance supports precise regulation in 36 V-class power rails without external trimming.
Does HZS36-1TD-E support automated PCB assembly?
Yes, the HZS36-1TD-E uses the MHD package (JEITA code GRZZ0002ZC-A) explicitly designed for 5 mm-pitch high-speed automatic insertion, as confirmed in the "Ordering Information" section of the Renesas datasheet. Its axial lead geometry and standardized dimensions ensure compatibility with standard pick-and-place and wave soldering equipment.
What is the maximum allowable reverse leakage current for HZS36-1TD-E?
The HZS36-1TD-E specifies a maximum reverse leakage current (IR) of 1 µA at VR = 18.2 V (0.5 × VZ min), measured at Ta = 25°C. This low leakage supports energy-efficient designs in standby or battery-operated applications where quiescent current must remain below microampere thresholds.
Can HZS36-1TD-E be used in high-temperature environments?
Yes, the HZS36-1TD-E is rated for a junction temperature (Tj) up to 200°C and storage temperature from −55°C to +175°C. When mounted on PCBs with adequate copper pour, it sustains stable regulation in industrial enclosures exceeding 100°C ambient-provided power dissipation remains within the derated curve shown in Figure 3 of the datasheet.
Is HZS36-1TD-E compliant with RoHS and environmental regulations?
Yes, HZS36-1TD-E complies with the EU RoHS Directive, as confirmed by Renesas Electronics' environmental compliance statements.
