Product details
Overview
SMBJ160A-E3/5B from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power rails and signal lines. It features a 160 V standoff voltage (VWM), 178–197 V breakdown range (VBR at 1 mA), 259 V clamping voltage (VC) at 2.3 A peak pulse current, and 600 W peak pulse power rating per 10/1000 µs waveform - deployed in industrial motor drives, telecom power supplies, and automotive body control modules.
For engineers reviewing the SMBJ160A-E3/5B datasheet, SMBJ160A-E3/5B pinout, SMBJ160A-E3/5B application, or SMBJ160A-E3/5B equivalent, key selection criteria include clamping performance under 2.3 A surge, thermal resistance (RθJA = 100 °C/W), RoHS-compliant matte tin terminations, and compatibility with automated SMT placement on SMB (DO-214AA) footprint.
Technical Context
This unidirectional TVS diode operates as a fast-acting shunt clamp, activating when reverse voltage exceeds its VBR threshold to divert transient energy away from downstream ICs or MOSFETs. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and repeatable breakdown behavior across temperature.
Designed for single-polarity transients, SMBJ160A-E3/5B exhibits 150 °C maximum junction temperature, 100 A non-repetitive forward surge rating (IFSM), and meets J-STD-020 MSL Level 1 - enabling reflow compatibility up to 260 °C peak without preconditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 160 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR (Breakdown Voltage) | 178–197 V at 1 mA - precise conduction onset window ensuring reliable overvoltage detection |
| VC (Clamping Voltage) | 259 V at IPPM = 2.3 A - limits downstream voltage stress during 10/1000 µs surge events |
| PPPM (Peak Pulse Power) | 600 W - sustains high-energy transients without failure under defined waveform conditions |
| IPPM (Peak Pulse Current) | 2.3 A - maximum surge current it can safely clamp per 10/1000 µs waveform |
| RθJA (Junction-to-Ambient) | 100 °C/W - defines thermal derating slope; requires copper pad area ≥5.0 mm × 5.0 mm for full power rating |
| TJmax | 150 °C - sets upper limit for thermal design margin in enclosed or high-ambient environments |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with cathode band marking. Matte tin-plated leads meet J-STD-002 solderability and JESD22-B102 whisker resistance Class 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional configuration |
| Cathode | Reverse-biased clamping terminal | Connected to protected line (e.g., 160 V rail); band denotes cathode end per polarity convention |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Enables protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) on 160 V systems |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients, improving clamping fidelity |
| Glass passivated junction | Ensures long-term parameter stability and low leakage (<1.0 µA) across temperature and life cycle |
| MSL Level 1, 260 °C peak reflow | Supports standard lead-free SMT assembly without moisture sensitivity handling |
| RoHS-compliant, commercial grade (E3 suffix) | Meets global environmental compliance requirements without halogen restrictions |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A-M3/5B | Halogen-free, RoHS-compliant variant with identical electrical specs and SMB package | Required where halogen-free material declaration is mandated (e.g., EU public infrastructure projects) | Select M3 suffix when halogen-free compliance is contractually required; otherwise E3 offers standard commercial qualification. |
| SMBJ160AHM3_B/I | AEC-Q101 qualified, halogen-free, 13" tape-and-reel packaging; same VWM/VC/PPPM | Qualified for automotive under-hood use (e.g., engine control units) requiring extended temperature and reliability validation | Choose HM3_B/I only for AEC-Q101–mandated automotive designs; not necessary for industrial or telecom applications. |
Compared with SMBJ160A-E3/5B, the M3/5B alternative provides identical protection performance with halogen-free materials, while the HM3_B/I version adds automotive qualification and different packaging - neither is pin-compatible drop-in replacements but share identical SMB footprint and electrical interface.

FAQ
What is the clamping voltage of SMBJ160A-E3/5B at its rated peak pulse current?
The SMBJ160A-E3/5B has a maximum clamping voltage (VC) of 259 V when subjected to its rated peak pulse current of 2.3 A under the standard 10/1000 µs waveform. This value is measured per Figure 1 in Vishay document 88392 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBJ160A-E3/5B maintains this clamping performance across its specified operating temperature range.
Is SMBJ160A-E3/5B suitable for bidirectional transient protection?
No, SMBJ160A-E3/5B is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. For bidirectional protection, Vishay specifies the "CA" suffix (e.g., SMBJ160CA). Using SMBJ160A-E3/5B in bidirectional applications would result in forward conduction during negative transients, potentially damaging the device or failing to protect the circuit. Always verify polarity alignment before integrating SMBJ160A-E3/5B.
What is the thermal resistance and recommended PCB layout for SMBJ160A-E3/5B?
The SMBJ160A-E3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as defined in the Vishay SMBJ datasheet. To achieve rated 600 W pulse power, designers must implement minimum pad dimensions and consider thermal vias beneath the terminals. Derating is required above 25 °C ambient per Figure 2 in document 88392. The SMBJ160A-E3/5B thermal performance is validated only with this layout.
Does SMBJ160A-E3/5B meet automotive qualification standards?
No, SMBJ160A-E3/5B is a commercial-grade part (E3 suffix) and is not AEC-Q101 qualified. Vishay offers automotive variants under the HE3 or HM3 suffixes (e.g., SMBJ160AHM3_B/I), which undergo additional stress testing and process controls for automotive under-hood applications. SMBJ160A-E3/5B is intended for industrial, telecom, and consumer applications where AEC-Q101 is not mandated. Always confirm qualification status via the full ordering code before automotive deployment.
What does the "/5B" in SMBJ160A-E3/5B indicate?
"/5B" denotes the preferred package code specifying 13-inch diameter plastic tape-and-reel delivery with a base quantity of 3200 units per reel, per Vishay's ordering information table. It is distinct from "/52", which indicates 7-inch reels of 750 units. The "E3" suffix confirms RoHS-compliant, commercial-grade construction with matte tin terminations. Together, SMBJ160A-E3/5B identifies both compliance level and logistics format - critical for procurement and SMT line setup.
