Product details
Overview
BZW04-213 from Taiwan Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for high-energy surge protection in automotive and industrial power rails. It features a 213 V working stand-off voltage (VWM), 237–263 V breakdown voltage (VBR) at 1 mA, 344 A peak pulse current (IPP), 400 W peak pulse power (PPK) at 10/1000 µs, and 0.110 %/°C temperature coefficient - deployed to safeguard microcontrollers and power ICs against EFT and load-dump transients.
For engineers reviewing the BZW04-213 datasheet, BZW04-213 pinout, BZW04-213 application, or BZW04-213 equivalent, key selection criteria include clamping voltage (VC = 344 V @ IPP), low leakage (<1 µA @ VWM), DO-41 package thermal performance (RθJA = 100 °C/W), and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
The BZW04-213 operates as a silicon avalanche diode with unidirectional polarity, triggered when reverse voltage exceeds its specified VBR range. Its clamping action limits transient-induced overvoltage to ≤344 V during 10/1000 µs surges, enabling robust protection of downstream 200–240 V DC systems without sacrificing response time.
Designed for non-repetitive surge events, it sustains 400 W peak power only at TA = 25°C and derates linearly above that ambient - requiring thermal design consideration for PCB copper pad area (5 × 5 mm per lead) and junction-to-lead resistance (RθJL = 60 °C/W) in high-reliability applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 213 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR @ IT=1 mA | 237–263 V - precise avalanche onset range defining turn-on threshold tolerance |
| VC @ IPP | 344 V - clamped voltage under 344 A surge, limiting stress on protected ICs |
| PPK | 400 W - peak transient energy absorption capability at 10/1000 µs waveform |
| ID @ VWM | <1 µA - negligible standby leakage, critical for low-power system battery drain control |
| TJ max | +175 °C - extended junction temperature rating supporting under-hood automotive deployment |
| Temperature Coefficient | 0.110 %/°C - predictable VBR drift over temperature, enabling accurate margining in thermal design |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ210A | Same DO-41 package, 210 V VWM, 233–258 V VBR, 337 V VC @ 342 A - slightly lower clamping voltage but no AEC-Q101 option | Used in commercial-grade telecom and industrial SMPS where automotive qualification is not required | Select when cost sensitivity outweighs AEC-Q101 compliance needs and tighter clamping is prioritized |
| Vishay 1.5KE220A | Higher PPK (1500 W), larger DO-201 package (not DO-41), 220 V VWM, 244–269 V VBR, 360 V VC @ 417 A - greater surge capacity but incompatible footprint | Deployed in high-energy UPS and motor drive systems where board space allows larger packages | Choose only if layout revision permits DO-201 replacement and 1500 W surge headroom is mandatory |
Compared with SMAJ210A and 1.5KE220A, the BZW04-213 uniquely balances AEC-Q101 qualification, DO-41 form factor, and precise 213 V standoff - making it optimal for space-constrained automotive ECUs requiring validated reliability without footprint change.

FAQ
What is the clamping voltage of the BZW04-213 under standard surge conditions?
The BZW04-213 exhibits a maximum clamping voltage (VC) of 344 V when subjected to its rated peak pulse current (IPP) of 344 A under the 10/1000 µs waveform. This value is measured at TA = 25°C and defines the upper voltage limit imposed on protected circuitry during surge events. The BZW04-213 maintains this clamping performance consistently across its operational junction temperature range of –55 °C to +175 °C, with minor variation governed by its 0.110 %/°C VBR temperature coefficient.
Is the BZW04-213 suitable for bidirectional surge protection applications?
No, the BZW04-213 is a unidirectional TVS diode and is not rated for bidirectional operation. Its datasheet specifies parameters only for unidirectional configuration - including polarity marking (cathode band), forward surge current rating (IFSM = 40 A), and reverse-biased clamping behavior. For bidirectional protection, the designated variant is BZW04-213B, which has identical VWM and VBR ratings but symmetrical breakdown in both polarities. Using BZW04-213 in place of BZW04-213B may result in forward conduction failure during positive transients.
Does the BZW04-213 meet AEC-Q101 qualification requirements?
Yes, the BZW04-213 is explicitly listed as AEC-Q101 qualified in the official Taiwan Semiconductor documentation. This qualification covers stress tests including high-temperature operating life (HTOL), temperature cycling (TCT), electrostatic discharge (HBM/MM), and mechanical shock - confirming suitability for automotive electronic control units (ECUs). Note that AEC-Q101 compliance applies only to parts ordered with the "H" suffix (e.g., BZW04-213H); standard BZW04-213 parts without the suffix are not certified.
What is the maximum steady-state power dissipation for the BZW04-213?
The BZW04-213 has a steady-state power dissipation (PD) rating of 1 W when mounted on 5 × 5 mm copper pads per lead at TL = 75°C. This value reflects continuous DC or low-frequency power handling capability - distinct from its 400 W peak pulse rating. Exceeding 1 W in sustained operation risks thermal runaway due to the device's RθJA of 100 °C/W; therefore, the BZW04-213 must be used exclusively for transient suppression, not for continuous voltage regulation or power dissipation tasks.
How does the junction-to-ambient thermal resistance affect PCB layout for the BZW04-213?
The BZW04-213 has a junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on a standard PCB with 10 mm lead length - meaning each watt of dissipated power raises the junction temperature by 100 °C above ambient. To maintain safe operation below its +175 °C TJ max, PCB layout must incorporate minimum 5 × 5 mm copper pads per terminal (as specified) and avoid thermal isolation. Reducing pad size or using thin traces increases RθJA, potentially causing premature thermal shutdown or parametric shift during repeated surge events.
