Product details
Overview
HZM36NB-JTR-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for voltage stabilization in low-power analog and digital supply rails, featuring a nominal zener voltage of 36 V (34–38 V range), 2 mW reverse current test condition, 27 Ω dynamic resistance at 2 mA, 200 mW power dissipation, and MPAK surface-mount package. It serves as a precision reference in power supply feedback loops, overvoltage protection circuits, and sensor biasing networks.
For engineers reviewing the HZM36NB-JTR-E datasheet, HZM36NB-JTR-E pinout, HZM36NB-JTR-E application, or HZM36NB-JTR-E equivalent, key selection criteria include its ±5.6% zener voltage tolerance (Grade B), temperature coefficient of +0.09 mV/°C near 36 V, junction temperature limit of 150°C, and suitability for high-density PCB layouts requiring SC-59A-compatible footprint.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled VZ characteristics across ambient temperatures. Its epitaxial planar structure ensures stable breakdown behavior and low noise, while the MPAK package enables thermal performance consistent with JEITA PLSP0003ZC-A standards.
Electrical validation is performed using 40 ms pulse testing to minimize self-heating effects. The device exhibits a positive temperature coefficient (+0.09 mV/°C) at 36 V, indicating increasing VZ with rising junction temperature - critical for thermal drift compensation in reference designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 34.0–38.0 V at IZ = 2 mA - defines stable regulation window for 36 V nominal rail clamping |
| Dynamic Resistance (rd) | 90 Ω max at IZ = 2 mA - determines output impedance and load regulation sensitivity |
| Reverse Current (IR) | 2 μA max at VR = 27 V - specifies leakage below breakdown, critical for low-power standby circuits |
| Power Dissipation (Pd) | 200 mW at Ta = 25°C - sets maximum continuous DC power handling before thermal derating |
| Junction Temperature (Tj) | 150°C maximum - constrains operating ambient and PCB copper area requirements for thermal management |
| Temperature Coefficient (γZ) | +0.09 mV/°C at VZ ≈ 36 V - quantifies VZ drift per degree, enabling thermal error budgeting |
Pinout & Package
Package: MPAK (JEITA code PLSP0003ZC-A), equivalent to SC-59A footprint; 3-terminal surface-mount package with 1.0 mm × 1.3 mm body, 0.35–0.5 mm lead width, and 2.7–3.1 mm overall length.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally unconnected terminal - must remain floating; no routing or soldering required |
| 2 | Anode | Cathode-side reference connection point - tied to lower-potential node in reverse-bias configuration |
| 3 | Cathode | High-side terminal - connected to regulated voltage node or feedback input in shunt regulator topologies |
Key Features
| Feature | Design Value |
|---|---|
| Grade-B Zener tolerance | ±5.6% VZ (34–38 V) - enables cost-effective stabilization without tight-bin sorting |
| MPAK surface-mount package | SC-59A-compatible footprint - supports automated placement and reflow, ideal for space-constrained boards |
| Pulse-tested VZ specification | Validated under 40 ms pulses - ensures parameter accuracy independent of thermal runaway during test |
| Low leakage at rated VR | ≤2 μA at 27 V - minimizes quiescent current in battery-powered or always-on monitoring circuits |
| Positive temperature coefficient | +0.09 mV/°C near 36 V - allows predictable drift modeling for temperature-compensated references |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C36LT1G | 36 V nominal, ±5% tolerance, SOT-23 package, 350 mW Pd, rd = 90 Ω @ 5 mA | Higher power rating but larger footprint; requires different pad layout and thermal relief | Select when higher surge energy handling or legacy SOT-23 compatibility is required |
| MMSZ5245B-TP | 36 V nominal, ±5% tolerance, SOD-123 package, 500 mW Pd, rd = 130 Ω @ 20 mA | Higher power and current capability but degraded dynamic resistance and looser tempco (±0.02%/°C) | Select when board-level transient immunity exceeds 200 mW but zener stability is secondary to robustness |
Compared with HZM36NB-JTR-E, BZX84-C36LT1G offers higher power margin in same functional role but demands PCB redesign, while MMSZ5245B-TP trades tighter VZ control for ruggedness - making HZM36NB-JTR-E optimal for space-constrained, thermally stable 36 V reference applications.

FAQ
What is the exact zener voltage range specified for HZM36NB-JTR-E?
The HZM36NB-JTR-E has a guaranteed zener voltage range of 34.0 V to 38.0 V at a test current of 2 mA, corresponding to Grade B tolerance per Renesas datasheet R07DS0358EJ0600. This 4 V span reflects ±5.6% deviation from the nominal 36 V rating and is validated under pulsed conditions to avoid thermal artifacts. The HZM36NB-JTR-E maintains this specification across its qualified operating temperature range.
Does HZM36NB-JTR-E have a pin 1 connection, and how should it be handled on the PCB?
No - pin 1 of the HZM36NB-JTR-E is designated NC (No Connect) and is internally unconnected. Per the official pin arrangement diagram, only pins 2 (Anode) and 3 (Cathode) are electrically active. Pin 1 must remain unconnected on the PCB: no trace, pad, or solder joint should be assigned to it. This avoids unintended parasitic coupling or mechanical stress on the die bond wire.
What is the maximum allowable reverse current for HZM36NB-JTR-E before entering breakdown?
The maximum reverse current (IR) for HZM36NB-JTR-E is 2 μA at a reverse voltage (VR) of 27 V, as specified in the Electrical Characteristics table. This leakage value is measured well below the minimum zener voltage (34 V), confirming minimal conduction in pre-breakdown region. Exceeding 27 V risks initiating uncontrolled breakdown, so HZM36NB-JTR-E must be operated above 34 V only in intentional reverse-bias regulation mode.
How does the temperature coefficient of HZM36NB-JTR-E affect its performance in a 36 V reference circuit?
The HZM36NB-JTR-E exhibits a temperature coefficient of +0.09 mV/°C near 36 V, meaning its zener voltage increases linearly with junction temperature. Over a 100°C rise (e.g., from 25°C to 125°C), VZ shifts by +9 mV - a +0.025% change relative to 36 V. This predictable drift allows designers to compensate in firmware or analog trimming, distinguishing HZM36NB-JTR-E from less stable alternatives where tempco is unspecified or nonlinear.
Is HZM36NB-JTR-E suitable for use in automotive applications, and what quality grade does it carry?
HZM36NB-JTR-E is classified as a "Standard" quality grade device per Renesas' product grading policy, intended for computers, office equipment, communications gear, and industrial robots - not for automotive safety-critical systems. It lacks AEC-Q101 qualification and is not approved for under-hood or chassis-control use. For automotive applications, Renesas recommends verified AEC-Q101 Zener diodes such as the RZM series; HZM36NB-JTR-E should only be used in non-safety automotive infotainment or accessory modules with explicit customer approval.
