Product details
Overview
HZM22NB1TL-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for precision voltage stabilization in low-power analog and reference circuits. It delivers a nominal zener voltage of 22.93 V to 23.96 V at 5 mA test current, with dynamic resistance of 55 Ω, power dissipation rating of 200 mW, and operates within –55°C to +150°C storage temperature range. It is commonly used in voltage regulation for sensor biasing and power supply feedback networks.
For engineers reviewing the HZM22NB1TL-E datasheet, HZM22NB1TL-E pinout, HZM22NB1TL-E application, or HZM22NB1TL-E equivalent, key selection criteria include its B1-grade zener voltage tolerance (±2.2%), MPAK surface-mount package compatibility with high-density PCB layouts, thermal performance under ambient conditions up to 75°C, and suitability for stable reference generation in industrial control modules.
Technical Context
The HZM22NB1TL-E employs a silicon epitaxial planar junction structure optimized for low-noise, stable reverse breakdown behavior. Its zener voltage exhibits a positive temperature coefficient of approximately +0.06 mV/°C near 22 V, enabling predictable drift compensation in multi-device references.
It operates exclusively in reverse-bias mode with no forward conduction role; terminal 1 is NC (no internal connection), terminals 2 and 3 serve as anode and cathode respectively. The device is rated for 2 mA maximum reverse leakage at VR = 17.0 V and requires strict thermal management due to its 200 mW power limit and 150°C max junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 22.93 V to 23.96 V at IZ = 5 mA - defines stable regulation point for feedback loops |
| Dynamic Resistance (rd) | 55 Ω at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Power Dissipation (Pd) | 200 mW at Ta = 25°C - sets maximum continuous power before thermal derating begins |
| Reverse Current (IR) | ≤2 μA at VR = 17.0 V - ensures minimal quiescent current in standby regulation |
| Junction Temperature (Tj) | 150°C maximum - constrains PCB copper area and airflow requirements for reliability |
| Temperature Coefficient (γZ) | +0.06 mV/°C - enables predictable voltage drift over operating temperature range |
| Package | MPAK (PLSP0003ZC-A) - 3-pin surface-mount package with 1.0 mm × 1.3 mm footprint |
Pinout & Package
Package: MPAK (JEITA code PLSP0003ZC-A), 3-terminal surface-mount plastic package with 1.0 mm × 1.3 mm body size, 0.35–0.5 mm lead width, and 0.1–0.26 mm thickness. Terminal 1 is unconnected (NC); terminals 2 and 3 form the anode–cathode pair.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage stabilization applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5255BTR | Zener voltage 22.8–23.7 V at 9.5 mA; TO-92 package; 500 mW Pd; rd ≈ 35 Ω | Through-hole mounting; higher power handling but larger footprint and slower thermal response | Select when legacy through-hole assembly or higher pulse power margin is required; not drop-in for MPAK layout |
| BZX84-C24LT1G | Zener voltage 22.8–25.2 V at 5 mA; SOT-23 package; 300 mW Pd; rd ≈ 80 Ω | Same surface-mount format but wider VZ tolerance (±5%); higher dynamic resistance degrades load regulation | Choose for cost-sensitive designs where ±5% reference accuracy is acceptable and 80 Ω rd meets stability requirements |
Compared with HZM22NB1TL-E, the 1N5255BTR offers higher power margin but requires PCB rework for through-hole insertion, while the BZX84-C24LT1G matches MPAK's SMT compatibility but trades 2.2% VZ tolerance and 55 Ω rd for broader availability and lower unit cost at volume.

FAQ
What is the exact zener voltage range for HZM22NB1TL-E at 5 mA test current?
The HZM22NB1TL-E has a guaranteed zener voltage range of 22.93 V to 23.96 V when tested at IZ = 5 mA and Ta = 25°C. This B1-grade specification reflects ±2.2% tolerance around the nominal 22 V point and is verified per Renesas preliminary datasheet R07DS0358EJ0600 Rev.6.00. Designers should use the full min/max range - not just the center value - for worst-case analysis of HZM22NB1TL-E in feedback networks.
Is terminal 1 of HZM22NB1TL-E electrically connected internally?
No, terminal 1 of the HZM22NB1TL-E is designated NC (No Connection) and is not bonded to any internal semiconductor structure. Per the official pin arrangement diagram in the Renesas datasheet, only terminals 2 (anode) and 3 (cathode) carry functional current. Leaving terminal 1 unconnected or grounding it per PCB layout best practices does not affect HZM22NB1TL-E electrical performance, but floating it avoids unintended parasitic coupling.
What is the maximum allowable reverse voltage before significant leakage occurs in HZM22NB1TL-E?
The HZM22NB1TL-E specifies a maximum reverse current IR ≤ 2 μA at VR = 17.0 V. This means that below 17.0 V, leakage remains negligible for most precision applications. Operation above this voltage approaches the zener knee region, where current rises exponentially. For reliable shunt regulation, HZM22NB1TL-E must be biased above its minimum zener voltage (22.93 V) - so 17.0 V is a sub-threshold test condition, not an operational limit.
Can HZM22NB1TL-E be used in place of older HZM22N variants?
Yes, HZM22NB1TL-E replaces earlier HZM22N grade-B versions with tighter voltage tolerance (B1 vs. B grade) and identical MPAK packaging and pinout. The B1 grade narrows the VZ range from 22.23–23.17 V (B grade) to 22.93–23.96 V, improving reference accuracy without layout changes. All absolute maximum ratings, thermal characteristics, and dynamic resistance values remain unchanged - making HZM22NB1TL-E a direct upgrade for existing HZM22N designs requiring improved regulation stability.
What is the thermal resistance from junction to ambient for HZM22NB1TL-E in standard FR-4 PCB layout?
The datasheet does not specify a numerical junction-to-ambient thermal resistance (θJA) for HZM22NB1TL-E. Instead, Figure 3 provides the derating curve: power dissipation drops linearly from 200 mW at 25°C ambient to 0 mW at ~125°C ambient on a standard 1.6 mm FR-4 board with 1.0 mm × 0.8 mm copper pads. From this, effective θJA is approximately 475°C/W - meaning a 100 mW power dissipation raises junction temperature by ~47.5°C above ambient. This value assumes minimal copper pour; adding thermal vias reduces θJA significantly for HZM22NB1TL-E in thermally demanding applications.
