Product details
Overview
P6SMB13CAHM3_B/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on signal or power lines. It features a 13 V standoff voltage (VWM), 18.2 V maximum clamping voltage at 33.0 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 μs waveform. It is halogen-free, RoHS-compliant, AEC-Q101 qualified, and used for protecting MOSFETs, ICs, and sensor signal lines in automotive and industrial electronics.
For engineers reviewing the P6SMB13CAHM3_B/I datasheet, P6SMB13CAHM3_B/I pinout, P6SMB13CAHM3_B/I application, or P6SMB13CAHM3_B/I equivalent, key selection criteria include bidirectional clamping performance, AEC-Q101 qualification status, SMB (DO-214AA) package compatibility, thermal resistance (RθJA = 100 °C/W), and compliance with IEC 61000-4-2/4-4/4-5 surge immunity standards.
Technical Context
This device operates as a bidirectional avalanche diode, symmetrically clamping both positive and negative transients above its breakdown voltage (VBR = 12.4–13.7 V at 1.0 mA). Its glass-passivated junction ensures stable leakage (<5.0 μA at VWM) and fast response time (<1.0 ns), enabling protection against ESD, lightning-induced surges, and inductive switching spikes.
Thermally, it supports operation from –65 °C to +150 °C junction temperature, with derated peak pulse power above 25 °C per Fig. 2. The SMB (DO-214AA) package provides low-profile mounting, meets UL 94 V-0 flammability rating, and is qualified for automated placement per J-STD-002 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 11.1 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown) | 12.4–13.7 V at 1.0 mA - Verified avalanche onset range; ensures predictable turn-on during transients. |
| VC (Clamping) | 18.2 V at 33.0 A - Peak voltage seen by protected circuit under 10/1000 μs surge; limits stress on downstream components. |
| PPPM | 600 W - Sustains 10/1000 μs transient energy without failure; enables robust protection in harsh environments. |
| IPPM | 33.0 A - Peak surge current handled at rated clamping voltage; determines minimum trace width and PCB layout margin. |
| TJ max. | +150 °C - Maximum junction temperature; supports under-hood automotive and high-ambient industrial use. |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient; informs heatsinking requirements for repetitive surge conditions. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); cathode/anode terminals are symmetrical and non-polarized.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional terminal pair | Either end serves as anode or cathode depending on transient polarity; no marking required per bidirectional design. |
Key Features
| Feature | Design Value |
|---|---|

| 600 W peak pulse power | Handles high-energy transients common in 12 V/24 V automotive systems and industrial motor drives without degradation. |
| Low clamping ratio (VC/VBR ≈ 1.4) | Minimizes overvoltage stress on protected ICs-critical for 3.3 V or 5 V logic interfaces exposed to fast transients. |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without preconditioning; eliminates moisture-related popcorning risk. |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Protection |
|---|---|

IC Role / Device Role / Timing Role: Low-capacitance bidirectional suppressor placed adjacent to ADC input to prevent ESD-induced offset drift. Use Value: Clamps ±15 kV contact ESD per IEC 61000-4-2 without altering sensor signal fidelity due to minimal leakage (<5 μA). |
Use Scenario: Protects RS-485 transceiver data lines in outdoor telecom cabinets exposed to lightning-induced ground potential rise. IC Role / Device Role / Timing Role: Primary line-level TVS mounted at board edge to divert surge energy away from transceiver ESD protection diodes. Use Value: Absorbs 600 W surge energy while maintaining <18.2 V clamping, preserving signal integrity and avoiding false data corruption. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13CA | Same VWM (11.1 V) and VC (18.2 V), but lower PPPM (400 W) and higher RθJA (130 °C/W); SMA package (smaller footprint, lower surge capacity). | Limited to lower-energy transients; unsuitable for automotive load dump or industrial motor drive scenarios requiring 600 W rating. | Select only when space constraints dominate and surge energy remains below 400 W. |
| 1.5KE13CA | Higher PPPM (1500 W), axial-leaded TO-204AE package; VC = 21.2 V at 71.5 A; not surface-mountable. | Requires through-hole assembly and larger board area; incompatible with automated SMT lines and compact PCB layouts. | Choose only for legacy through-hole designs where higher surge margin justifies manual assembly and layout overhead. |
Compared with SMAJ13CA and 1.5KE13CA, P6SMB13CAHM3_B/I uniquely delivers AEC-Q101 qualification, halogen-free compliance, and 600 W surge handling in an automated-placement-ready SMB package-making it the optimal choice for new automotive and industrial SMT designs requiring certified reliability and regulatory alignment.

FAQ
What is the clamping voltage of P6SMB13CAHM3_B/I under a 10/1000 μs surge?
The P6SMB13CAHM3_B/I has a maximum clamping voltage (VC) of 18.2 V when subjected to its rated peak pulse current of 33.0 A using a 10/1000 μs waveform. This value is measured per standard test conditions (TA = 25 °C) and defines the upper voltage limit imposed on protected circuitry during surge events. The P6SMB13CAHM3_B/I maintains this clamping performance across its full operating temperature range.
Is P6SMB13CAHM3_B/I suitable for automotive applications?
Yes, P6SMB13CAHM3_B/I is AEC-Q101 qualified and specifically designated for automotive use with the "HM3_B" suffix indicating halogen-free, RoHS-compliant, and AEC-Q101-qualified construction. It meets stringent automotive reliability requirements including temperature cycling, mechanical shock, and humidity bias testing. The P6SMB13CAHM3_B/I is commonly deployed in body control modules, infotainment power supplies, and sensor interface protection.
What does the "CA" suffix mean in P6SMB13CAHM3_B/I?
The "CA" suffix in P6SMB13CAHM3_B/I denotes a bidirectional configuration-meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., P6SMB13A), the CA version has no polarity marking and functions identically regardless of voltage polarity applied across its terminals. This makes the P6SMB13CAHM3_B/I ideal for AC-coupled lines or differential signal protection.
What is the standoff voltage (VWM) of P6SMB13CAHM3_B/I?
The standoff voltage (VWM) of P6SMB13CAHM3_B/I is 11.1 V-this is the maximum DC or continuous reverse working voltage the device can withstand without entering avalanche conduction. It provides a safety margin below the minimum breakdown voltage (12.4 V) and ensures stable operation during normal system conditions. The P6SMB13CAHM3_B/I remains non-conductive until transients exceed this threshold.
Does P6SMB13CAHM3_B/I require a heatsink for standard operation?
No, P6SMB13CAHM3_B/I does not require an external heatsink for single-event transient suppression under typical conditions. Its RθJA of 100 °C/W and 5.0 W steady-state power dissipation rating are sufficient for intermittent surge duty cycles (e.g., 0.01 % duty cycle per datasheet). However, for repetitive surges or high ambient temperatures (>70 °C), PCB copper pad area should follow Vishay's recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) layout to maintain thermal performance. The P6SMB13CAHM3_B/I relies on PCB thermal mass-not external heatsinks-for thermal management.
