Product details
Overview
SMBJ60CAHE3/5B 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 60 V stand-off voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 96.8 V maximum clamping voltage (VC) at 6.2 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies and telecom line cards.
For engineers reviewing the SMBJ60CAHE3/5B datasheet, SMBJ60CAHE3/5B pinout, SMBJ60CAHE3/5B application, or SMBJ60CAHE3/5B equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification status, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ leakage at VWM), then rapidly switches to low-impedance conduction when transient voltage exceeds VBR. Its glass-passivated junction ensures stable breakdown behavior and fast response time (<1 ns).
The SMBJ60CAHE3/5B is rated for repetitive 10/1000 µs surges at 0.01% duty cycle, derated above 25 °C per Fig. 2, with thermal resistance RθJA = 100 °C/W and RθJL = 20 °C/W - enabling reliable operation in compact PCB layouts without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 60 V - maximum continuous reverse operating voltage before significant leakage; defines safe operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 66.7–73.7 V at 1 mA - precise voltage threshold where device transitions from high- to low-impedance state |
| VC (Clamping Voltage) | 96.8 V at IPPM = 6.2 A - maximum voltage seen by protected circuit during 10/1000 µs transient; determines stress on downstream components |
| PPPM (Peak Pulse Power) | 600 W - energy-handling capacity for standardized 10/1000 µs surge; supports protection against IEC 61000-4-5 Level 3/4 transients |
| IPPM (Peak Pulse Current) | 6.2 A - maximum non-repetitive surge current the device can safely divert without degradation |
| TJmax | 150 °C - maximum junction temperature; enables use in high-ambient environments like motor drives and base stations |
| Package | SMB (DO-214AA) - industry-standard surface-mount outline with 0.220" × 0.155" footprint; compatible with J-STD-020 MSL level 1 reflow profile (260 °C peak) |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads; polarity-unmarked for bidirectional configuration; meets UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (bidirectional) | One terminal of symmetrical PN junction; conducts surge current in either direction when voltage exceeds |VBR| |
| Cathode | Transient current exit (bidirectional) | Second terminal of symmetrical structure; no band marking distinguishes polarity due to bidirectional symmetry |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns |
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness - suitable for under-hood ECUs |
| 600 W peak pulse power | Supports immunity to high-energy transients such as ISO 7637-2 pulse 5a/b and IEC 61000-4-5 combination wave surges |
| Low clamping ratio (VC/VBR ≈ 1.4) | Minimizes overvoltage stress on protected ICs - critical for 3.3 V/5 V logic and low-voltage gate drivers |
| MSL level 1 moisture sensitivity | Allows unlimited floor life and standard reflow without baking; reduces manufacturing overhead in high-volume SMT lines |
Applications
| Industrial Motor Drives | Automotive Body Control Modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60CA-M3/5B | Halogen-free, RoHS-compliant variant; identical electrical specs and AEC-Q101 qualification; same SMB package | No functional difference; selected when halogen-free material compliance is required for end-product environmental certification | Choose SMBJ60CA-M3/5B if EU EcoDesign or specific customer green-material mandates apply |
| SMAJ60CAHE3/A | Lower power rating (400 W vs. 600 W); SMA (DO-214AC) package with smaller footprint and higher thermal resistance (RθJA = 140 °C/W) | Not suitable for high-energy transients; limited to lower-duty-cycle or space-constrained designs where 600 W headroom is unnecessary | Choose SMAJ60CAHE3/A only when board area is critical and surge threat level is ≤IEC 61000-4-5 Level 2 |
Compared with SMBJ60CAHE3/5B, the M3 variant offers identical protection performance with halogen-free construction, while the SMAJ60CAHE3/A trades 33% peak power and thermal margin for 30% smaller PCB area - making SMBJ60CAHE3/5B the optimal choice for industrial and automotive applications demanding full 600 W surge resilience.

FAQ
What is the clamping voltage of SMBJ60CAHE3/5B at its rated peak pulse current?
The SMBJ60CAHE3/5B has a maximum clamping voltage (VC) of 96.8 V at IPPM = 6.2 A with a 10/1000 µs waveform. This value is measured under standardized test conditions per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuits during surge events. The SMBJ60CAHE3/5B maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C).
Is SMBJ60CAHE3/5B suitable for automotive applications?
Yes, SMBJ60CAHE3/5B is AEC-Q101 qualified and explicitly listed in Vishay's automotive ordering codes (HE3 suffix). It undergoes stress testing for temperature cycling, highly accelerated life testing (HALT), and ESD robustness per AEC-Q101 Rev D. The SMBJ60CAHE3/5B is deployed in body control modules, infotainment power rails, and LIN/CAN node protection where transient immunity and long-term reliability are critical.
How does the bidirectional design of SMBJ60CAHE3/5B affect its layout and usage?
The SMBJ60CAHE3/5B has no polarity marking and functions identically in both directions - simplifying PCB layout by eliminating orientation constraints during automated placement. This makes it ideal for protecting AC-coupled signals, floating grounds, or differential buses like RS-485 or CAN where voltage transients may swing positive or negative relative to reference. The SMBJ60CAHE3/5B requires no external biasing or directional routing.
What is the thermal resistance and power derating behavior of SMBJ60CAHE3/5B?
The SMBJ60CAHE3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W on 0.2" × 0.2" copper pads, and junction-to-lead resistance (RθJL) of 20 °C/W. Its peak pulse power must be derated linearly above 25 °C ambient per Figure 2 in the datasheet - e.g., at 85 °C TA, PPPM is reduced to ~420 W. Continuous power dissipation (PD) remains 5.0 W up to 50 °C with infinite heatsink.
Does SMBJ60CAHE3/5B meet moisture sensitivity and reflow requirements for automated assembly?
Yes, SMBJ60CAHE3/5B is rated MSL level 1 per J-STD-020, with a maximum reflow peak temperature of 260 °C. It has unlimited floor life and requires no pre-baking prior to soldering. The matte tin-plated leads comply with J-STD-002 and JESD 22-B102 for solderability, and the device passes JESD 201 class 2 whisker testing - ensuring robust manufacturability in high-throughput SMT lines.
