Product details
Overview
SMBJ160CAHE3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 160 V stand-off voltage (VWM), 178–197 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 µs), and clamps to ≤259 V at 2.3 A peak surge current - deployed in industrial motor drives and telecom power supplies.
For engineers reviewing the SMBJ160CAHE3/52 datasheet, SMBJ160CAHE3/52 pinout, SMBJ160CAHE3/52 application, or SMBJ160CAHE3/52 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), and compliance with UL 497B for surge protection systems.
Technical Context
This device operates as a voltage-clamping protector using an avalanche junction structure. Its bidirectional symmetry enables suppression of both positive and negative transients without polarity sensitivity, and it maintains stable clamping performance across -55 °C to +150 °C junction temperature range.
It delivers 600 W peak pulse power under standardized 10/1000 µs waveform conditions with 0.01 % duty cycle, and exhibits low incremental surge resistance for minimal voltage overshoot during fast-rising ESD or lightning-induced surges up to 2.3 A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 160 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 178 V / 197 V at 1 mA - guaranteed breakdown onset range defining transient detection threshold |
| VC @ IPPM | ≤259 V at 2.3 A - clamped voltage level limiting downstream component stress during surge events |
| PPPM | 600 W - peak transient energy absorption capacity under 10/1000 µs waveform |
| ID @ VWM | ≤1.0 µA - ultra-low leakage ensuring minimal standby power loss in high-impedance circuits |
| TJ max | +150 °C - maximum junction temperature enabling operation in under-hood automotive and industrial environments |
| RθJA | 100 °C/W - thermal resistance indicating required PCB copper area (0.2" × 0.2") for safe power dissipation |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry point (negative half-cycle) | Accepts reverse surge current during negative voltage excursions; symmetric with cathode for bidirectional operation |
| Cathode | Transient current entry point (positive half-cycle) | Accepts forward surge current during positive voltage excursions; electrically identical to anode in bidirectional mode |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness per JESD22 standards |
| 600 W peak pulse power | Enables single-device protection against IEC 61000-4-5 Level 4 (4 kV surge) on 24–48 V DC bus lines |
| UL 497B recognized | Meets Underwriters Laboratories requirements for telecom and data line protectors (File E136766) |
| MSL Level 1 | Zero moisture sensitivity - supports lead-free reflow up to 260 °C peak without preconditioning |
| Glass passivated junction | Ensures long-term stability of VBR and leakage under humidity and thermal stress in industrial deployments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160CA-M3/52 | Halogen-free, RoHS-compliant variant; identical electrical specs and AEC-Q101 qualification | No difference in circuit behavior or layout; differs only in material composition per environmental compliance requirements | Select when halogen-free manufacturing or IPC-1752 reporting is mandated |
| SMCJ160CAHE3/52 | Same VWM/VBR/VC but in larger SMC (DO-214AB) package; 1500 W PPPM rating vs. 600 W | Higher surge handling requires larger PCB footprint; not drop-in due to different pad layout and thermal mass | Choose only when system-level surge testing exceeds 600 W - e.g., outdoor telecom cabinets per ITU-T K.20 |
Compared with SMBJ160CAHE3/52, the M3 variant offers identical protection performance with halogen-free construction, while the SMCJ160CAHE3/52 provides higher surge margin at the cost of board space and thermal design changes - neither is pin-compatible, but both serve overlapping protection roles in industrial and automotive systems.

FAQ
What does the "CA" suffix indicate in SMBJ160CAHE3/52?
The "CA" suffix denotes a bidirectional configuration: SMBJ160CAHE3/52 suppresses transients of either polarity symmetrically, unlike unidirectional variants (e.g., SMBJ160AHE3/52) that protect only one voltage polarity. This makes SMBJ160CAHE3/52 ideal for AC-coupled lines, differential buses, or any application where voltage reversals occur.
Is SMBJ160CAHE3/52 qualified for automotive use?
Yes, SMBJ160CAHE3/52 carries the HE3 suffix, confirming AEC-Q101 qualification per Vishay's ordering nomenclature. It has undergone stress testing including temperature cycling, high-temperature reverse bias, and ESD per JESD22 standards - making SMBJ160CAHE3/52 suitable for under-hood and chassis-mounted automotive ECUs.
What is the maximum clamping voltage of SMBJ160CAHE3/52 during a surge event?
The maximum clamping voltage (VC) of SMBJ160CAHE3/52 is 259 V when subjected to its rated peak pulse current of 2.3 A (10/1000 µs waveform). This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during transient suppression - critical for ensuring downstream ICs remain within absolute maximum ratings.
How does the SMB (DO-214AA) package of SMBJ160CAHE3/52 compare thermally to larger packages?
SMBJ160CAHE3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads. While larger packages like SMC (DO-214AB) offer lower RθJA (~50 °C/W), the SMB footprint enables high-density placement near connectors or ICs - requiring careful thermal relief design but preserving board space for SMBJ160CAHE3/52 in space-constrained modules.
Does SMBJ160CAHE3/52 meet UL safety standards?
Yes, SMBJ160CAHE3/52 is UL 497B recognized (File E136766) for use in telecommunications and signal line protectors. This certification validates its ability to safely interrupt and clamp surges without fire hazard or insulation failure - a mandatory requirement for SMBJ160CAHE3/52 in telecom central office equipment and industrial Ethernet interfaces.
