Product details
Overview
HZM2.7NB1TL 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 2.7 V (min 2.80 V, max 3.05 V at IZ = 5 mA), with dynamic resistance of 110 Ω, power dissipation of 200 mW, and operates within –55 °C to +150 °C storage range - commonly used in voltage reference buffers for ADCs and sensor signal conditioning.
For engineers reviewing the HZM2.7NB1TL datasheet, HZM2.7NB1TL pinout, HZM2.7NB1TL application, or HZM2.7NB1TL equivalent, key selection criteria include its B1-grade zener tolerance (±4.6% at 25 °C), MPAK surface-mount package compatibility with high-density PCB layouts, low-temperature coefficient (–0.035 mV/°C near 2.7 V), and suitability for stable biasing in portable instrumentation and automotive body electronics.
Technical Context
The HZM2.7NB1TL employs a silicon epitaxial planar junction structure optimized for tight zener voltage control and low dynamic impedance. Its electrical behavior is characterized under pulsed test conditions (Pw = 40 ms) to minimize self-heating effects during measurement.
This device functions exclusively as a two-terminal shunt regulator, requiring an external current-limiting resistor. It exhibits no active control logic, temperature compensation circuitry, or integrated thermal shutdown - operation relies entirely on intrinsic semiconductor physics and specified test conditions at Ta = 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.80 V to 3.05 V at IZ = 5 mA - defines stable regulation point for low-voltage references. |
| Dynamic Resistance (rd) | 110 Ω max at IZ = 5 mA - determines output impedance and load regulation sensitivity. |
| 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 thermal design margin in enclosed or high-ambient environments. |
| Reverse Current (IR) | 120 µA max at VR = 1.0 V - specifies leakage level below breakdown, critical for standby power budgets. |
| Temperature Coefficient (γZ) | –0.035 mV/°C (typ.) near 2.7 V - quantifies drift magnitude over operating temperature range. |
Pinout & Package
Package: MPAK (JEITA code PLSP0003ZC-A), surface-mount, 3-pin, 1.0 mm × 1.3 mm footprint, 0.95 mm height, 0.011 g mass.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally unconnected terminal - must remain floating; no routing or soldering required. |
| 2 | Anode | Current entry point during forward bias; connected to lower-potential node in zener configuration. |
| 3 | Cathode | Current exit point during reverse breakdown; connected to regulated output node and current-limiting resistor. |
Key Features
| Feature | Design Value |
|---|---|
| Grade-B1 Zener Tolerance | ±4.6% (2.80–3.05 V at 5 mA) - enables tighter reference accuracy than standard-grade Zeners. |
| MPAK Surface-Mount Package | 0.95 mm height, 1.0 mm × 1.3 mm footprint - supports automated placement and high board density in space-constrained designs. |
| Pulsed Test Validation | Specified with Pw = 40 ms pulses - ensures parameter stability under transient measurement conditions without thermal error. |
| Low Leakage Performance | IR ≤ 120 µA at VR = 1.0 V - minimizes quiescent current draw in battery-powered reference circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C2V7LT1G | Zener voltage 2.5–2.9 V (±5%), 350 mW Pd, SOT-23 package, rd = 90 Ω typical | Higher power rating but larger footprint; less tight VZ tolerance than HZM2.7NB1TL's B1 grade | Preferred where higher surge energy handling is needed, but requires layout change due to SOT-23 vs. MPAK. |
| MMSZ4678T1G | Zener voltage 2.7 V (±5%), 500 mW Pd, SOD-123 package, rd = 100 Ω typical | Higher power and different thermal profile; lacks NC pin - all three terminals functional | Used when board-level thermal management allows larger package and higher dissipation, but not pin-compatible. |
Compared with BZX84-C2V7LT1G and MMSZ4678T1G, the HZM2.7NB1TL offers superior voltage tolerance (B1 grade ±4.6% vs. ±5%) and a dedicated NC pin enabling simplified routing in ultra-dense layouts, though at lower absolute power rating - making it optimal for compact, precision-referenced analog subsystems.

FAQ
What is the exact zener voltage range for HZM2.7NB1TL at 5 mA test current?
The HZM2.7NB1TL has a guaranteed zener voltage range of 2.80 V to 3.05 V when tested at IZ = 5 mA and Ta = 25 °C. This B1-grade specification reflects ±4.6% tolerance around the nominal 2.7 V rating, confirmed in Renesas' R07DS0358EJ0600 datasheet Table on page 2. The HZM2.7NB1TL achieves tighter regulation than standard-grade variants in the same family.
Does HZM2.7NB1TL require external current limiting, and what is the recommended value?
Yes, the HZM2.7NB1TL requires an external series current-limiting resistor to operate safely in reverse breakdown. For operation at IZ = 5 mA with a 5 V supply, a 460 Ω resistor (standard 1% value) delivers 4.8 mA - within spec and well below the 200 mW power limit. Derating is required above 25 °C per Figure 3 in the HZM2.7NB1TL datasheet.
What does the "NC" pin (Pin 1) on HZM2.7NB1TL signify, and how should it be handled on the PCB?
Pin 1 of the HZM2.7NB1TL is a No Connect terminal - internally unconnected and electrically isolated. It must remain unconnected on the PCB: no trace, pad, or solder mask opening is required. Routing or grounding Pin 1 may cause mechanical stress or unintended coupling; Renesas explicitly defines it as NC in the "Pin Arrangement" diagram on page 1 of the HZM2.7NB1TL datasheet.
How does the temperature coefficient of HZM2.7NB1TL affect long-term reference stability?
The HZM2.7NB1TL exhibits a typical temperature coefficient (γZ) of –0.035 mV/°C near 2.7 V, as shown in Figure 2 of the datasheet. Over a 0–70 °C ambient range, this results in ~2.5 mV total drift - approximately ±0.09% of nominal VZ. For high-stability applications, this drift must be compensated in system calibration; the HZM2.7NB1TL itself provides no active temperature correction.
Is HZM2.7NB1TL suitable for use in automotive applications, and which AEC-Q200 stress tests does it pass?
The HZM2.7NB1TL is rated for "Standard" quality grade per Renesas' internal classification (page 6, Note 7), covering automotive body electronics such as door modules and lighting controls - but not safety-critical or powertrain systems. It is not AEC-Q200 qualified; users requiring automotive qualification must select Renesas' designated AEC-Q200 Zener series or perform independent stress validation per their OEM requirements. The HZM2.7NB1TL datasheet does not list AEC-Q200 test results.
